Uponor Smatrix Base Pulse system description

Uponor Smatrix Base is a management system for underfloor heating and cooling installations. Comfort, user friendliness and temperature control for each individual room of a home can be combined through the various components.

System overview

Uponor Smatrix Base consists of a room controller, a communication module (optional), thermostats, and actuators. The room controller manages the operation of the actuators when the thermostats detect a demand for heating or cooling.

System optimization and settings (for up to four room controllers) is facilitated via the Uponor Smatrix Pulse app (connected via the communication module). The system can function without the communication module, but with reduced functionality.

Uponor Smatrix Base is controlled by different types of thermostats. Designed for maximum comfort, the thermostats communicate with the room controller by a wired communication protocol. It is possible to mix the different types of Uponor Smatrix Base thermostats in the same installation.

Example of a system

The illustration below shows Uponor Smatrix Base with several installation options and thermostats.

Error

The floor sensor can be connected to a thermostat (except the T-141, T-144, or T-145). Which can be used for floor temperature limitation.

For example, the maximum limitation can protect a sensitive floor covering from exposure of too high temperatures when there is a high heating demand. The minimum limitation can keep a tiled floor warm even when there is a no general heating demand for the room.

Uponor actuators

Uponor actuators are mounted on top of the manifold valves and is operated using either on/off signals or pulse width modulation (PWM) signals.

AActuator has closed the valve – empty indicator

On/off control

When installing a system with on/off control, manual balancing of the system is required.

As soon as the temperature measured at a thermostat is lower (heating mode) or higher (cooling mode) than the setpoint temperature, a demand to change the room temperature is created and sent to the room controller. The room controller will open the actuators according to current operating mode and other settings. Once the set temperature is reached, this information is sent and the actuators are closed. The indicator on the actuator shows, with a white bar, how much it is opened. If indicator (white) is fully shown it is fully opened, no white bar shown means that the actuator is closed.

Time to open and close an actuator may take a couple of minutes.

PWM control

Error

Autobalancing can be used in combination with hydronic balancing.

PWM control is used when the Autobalancing function is active.

When installing a system with PWM control, all balancing valves can be fully opened, the system is balanced automatically.

Functions

Error

Setting up a system with a communication module requires a mobile device (smart phone/tablet).

The Uponor Smatrix room controler is used to operate an underfloor heating and/or cooling system in a house.

The room controller can also control heating via electrical underfloor heating using an external relay.

The thermostats registered to the room controller is used to control the actuators mounted on top of the manifold valves.

As soon as the temperature measured at a thermostat is lower (heating mode) or higher (cooling mode) than the setpoint temperature, a demand to change the room temperature is created and sent to the room controller. The room controller will operate the actuators according to current control mode and settings. This will manage the flow to the floor loops in the room and adjust the room temperature. Once the set temperature is reached, this information is sent to the room controller and the demand is met.

Actuator management

Actuator management prevents too many actuators to be open at the same time in order to reduce the peak power need. Peak current can be reduced by delaying the opening of some actuators, as they use most current while being opened.

Up to eight actuators in up to six rooms can be opened at the same time. Additional actuators are queued and opened in order.

Autobalancing

Error

Autobalancing can be used in combination with hydronic balancing.

The room controller can operate the actuator outputs by either on/off signals or by Autobalancing (on by default), using pulse width modulation (PWM) signals.

Autobalancing is a function which ensures that the required amount of energy is used to maintain the defined room temperatures (setpoint) without the need of manual balancing.

The function calculates the timing of the actuators and cyclically adapts to changing conditions. That way, it is ensured at all times that the necessary amount of energy is made available to the rooms and thermal adjustment of the rooms takes place.

This results in more even floor temperatures and faster system reaction times with lower energy consumption than any standard on/off system.

Comfort and ECO modes

Error

Use only one Comfort/ECO switch in the system.

  • Connecting external Comfort/ECO switch to the system (public thermostat system device, or GPI), disables Forced ECO in the Uponor Smatrix Pulse app.

  • Connecting the external Comfort/ECO switch via the public thermostat system device, disables the Comfort/ECO option in the GPI.

Using the communication module and Uponor Smatrix Pulse app, or an external switch (connected to the GPI or public thermostat), it is possible to regulate the temperature setpoint modes between two different temperatures. Available modes are Comfort and ECO (economy).

Switching between the Comfort/ECO modes can automatically be scheduled by connecting the communication module to Uponor cloud services. Scheduling in systems without a communication module requires a programmable thermostat, but it can only schedule Comfort/ECO in the room where it is registered.

The diagram shows that the system delivers heating in comfort mode in the morning and afternoon, but the system enters ECO mode during night and in the middle of the day, when the house normally is empty.

Cooling function

The room controller operates the underfloor cooling installation according to customer needs. Temperatures can be adjusted with thermostats located in each room, or if installed with the Uponor Smatrix Pulse app (requires communication module).

As soon as the temperature measured at a thermostat is higher than the setpoint temperature, a demand to change the room temperature is created and sent to the room controller. The room controller will open the actuators according to current operating mode and other settings. If autobalancing is disabled, the actuators will open before the setpoint is reached. Once the set temperature is reached, this information is sent and the actuators are closed.

Uponor Smatrix Pulse app (requires communication module)

The system supports different types of cooling methods and is setup in the Uponor Smatrix Pulse app.

Available cooling methods in the Uponor Smatrix Pulse app.

  • Underfloor cooling (UC)

    Cooling in the system is achieved using underfloor loops.

  • Ceiling cooling (CC)

    Cooling in the system is achieved using ceiling cooling (2-pipe or 4-pipe system).

    Select if the system utilizes a 2-pipe or 4-pipe delivery solution for heating/cooling.

    • 2-pipe means one supply temperature to the system at a time (heating or cooling).

      Autoblancing disabled:In rooms where underfloor heating/cooling is allowed. Underfloor cooling and ceiling cooling is both started when the room termperature is about 1 degree below setpoint.

      Autobalancing enabled: Ceiling cooling and underfloor cooling will follow the current cooling demand.

    • 4-pipe means separate independent heating/cooling sources.

      In heating mode:

      The underfloor loops are used when there is a heating demand.

      In cooling mode:

      Underfloor loops and ceiling cooling are used at the same time when there is a cooling demand.

See Uponor Smatrix Pulse app for more information about the individual functions.

Electrical underfloor heating

The Uponor Smatrix room controller can operate electrical underfloor heating (Uponor Comfort-E) using the actuator outputs.

The electrical underfloor heating mat/wire must be connected to the controller via a relay (dimensioned for the correct load), because of 24V AC controller output.

Heating/cooling offset

Uponor uses an offset temperature to adjust the setpoints when switching between heating and cooling. This improves the performance of the system and reduces the need of manual setpoint adjustments when switching between heating and cooling.

The offset is 2 °C and is used to increase the setpoints when switching to cooling. When switching back to heating, the value is used to reduce the setpoint.

Heating fallback

If the connection to a thermostat is lost, the corresponding loop cannot be regulated using the room temperature. The room controller then activates a fallback function for the affected loop and the actuators are operated with a set interval.

The function is activated until the thermostat is reconnected.

Low hysteresis temperature

Uponor uses a low hysteresis temperature for best performance of the system. It is used for high control accuracy by deciding when to start and stop heating and cooling, based on information from sensors and setpoint values.

Pump management (requires communication module)

Error, enter correct language code

Changing status of the pump management and/or cooling allowed (in the Uponor Smatrix app, requires communication module) will set all relays to Not configured. Which will have to be configured again.

Error

In systems with multiple room controllers (master/sub configuration), all relays are initially set to Not configured. Which will have to be configured during installation.

Each room controller has a pump relay, to which one circulation pump can be connected. Default operating mode of the circulation pump is set to Individual mode. Use the Uponor Smatrix Pulse app (requires communication module) to change the setting if needed. Available settings are Not configured, Common and Individual.

Common mode:

Relay function is set on a system wide basis. One circulation pump per system is connected (to the master room controller only). When there is a demand somewhere in the system, the main pump is started.

Individual mode:

Relay function is set on a room controller basis. One circulation pump per room controller is connected. When there is a demand to a specific room controller, only the circulation pump connected to that room controller is started.

Relative humidity function

Error

RH control is activated in the Uponor Smatrix Pulse app (requires communication module).

To avoid condensation when having a cooling system, it is recommended measuring the relative humidity (RH) in the rooms. The relative humidity is measured with one or more thermostats (with RH sensor).

Cooling is shut off on a per room basis when the relative humidity limit is reached (set in the Uponor Smatrix Pulse app, default 75%). If a dehumidifier is installed, one per room controller, it will be activated when the dehumidifier start limit is reached.

Cooling will start again and the dehumidifier is deactivated when the relative humidity falls below a hysteresis set in the Uponor Smatrix Pulse app (“Deadzone”, default 5%).

Room bypass (requires communication module)

The system can use up to two rooms (per room controller), when in heating mode, as bypass to maintain minimum flow in the system.

Rooms can be selected manually or by using the Time limit room bypass function.

Time limit room bypass

The time limit room bypass function prevents shorter run times than 30 minutes in the system. The room controller analyzes available system data such as current and future demands, setpoints, and room temperatures etc. Depending on the result of the analysis, suitable rooms are chosen to use as bypass.

System clock

To facilitate accurate log data, scheduling and different timer settings, the room controller receives the correct time and date from one of the input devices (communication module connected to Uponor cloud services, programmable thermostat etc). The clock can be set to automatically switch between summer and winter time (communication module connected to Uponor cloud services only).

Uponor Smatrix Base Pulse system

Error

Setting up a system with a communication module requires a mobile device (smart phone/tablet).

A connection example of Uponor Smatrix Base Pulse room rontroller (six channels) with optional Uponor Smatrix Base Pulse Slave Module (six extra channels and three extra bus connectors), and Uponor Smatrix Base Pulse Star Module (eight extra bus connectors), using system devices (S) and thermostats (T) as shown in figure.

The installation will work in a standard way with the thermostats regulating each room according to their set temperatures.

Connections

The system is based on a bus communications protocol (requires the thermostats unique ID to be registered to the controller), utilising daisy chain, direct or star topology connections. This allows serial and parallel connections, making wiring and connection of thermostats and system devices much easier than connecting one thermostat per connection terminal.

The wide array of connection possibilities presented with this communications protocol can be combined in any way best suited for the current system.

Thermostats and actuators

  • Thermostat #01 controls actuator channels 01a, 01b, 02a and 02b with the help of an option.

  • Thermostat #03 controls actuator channels 03 to 05 with the help of an option.

  • Thermostat #06 controls actuator channels 06 and 07.

  • Thermostat #08 controls actuator channels 08 to 10 with the help of an option.

  • Thermostat #11 controls actuator channels 11 and 12.

System devices

Error

If registering a public thermostat with various functions as a system device, the thermostat only acts as a remote unit. It does not control the room temperature in the room where it is placed.

Error

System devices can only be registered to the master room controller.

Error

The room controller will time out after about 10 minutes of inactivity and revert to normal operation. The timer will be reset when a button is pressed or if a device has been registered to it.

Error

Sub room controllers can only be registered to the master room controller.

Error

If a room controller previously connected to a communication module is to be used as a sub room controller (or in a system without a communication module), restore it to sub room controller state by factory reset.

Existing sub room controllers in the system must then either, reset system device channel 01, or register to another master room controller.

  • Multiple room controllers

    Multiple Uponor Smatrix room controllers can be linked together by assigning one room controller to be master and the rest to be sub room controllers.

    The master room controller is assigned by connecting it to the communication module (only one room controller can be master in the system), and it can control up to three sub room controllers. Sub room controllers are assigned when registered (in order) to the master room controller.

  • Public thermostat T-143 with various functions (options B and C).

Option A

  • External temperature sensor.

  • Floor temperature sensor.

Option B

  • Outdoor temperature sensor.

Option C

  • External temperature sensor for heating/cooling switch.

  • Comfort/ECO mode switch.This option disables the Comfort/ECO option in the GPI.

Schedules

Programmable schedules can, during heating and/or cooling, switch between Comfort and ECO mode. See example below.

Schedule 1

Other rooms can, depending on system setup, simultaneously switch between Comfort and ECO mode according to their own programmed schedules.

This requires one or more of the following:

  • Uponor Smatrix Pulse app (requires communication module connected to Uponor cloud services)

    The app allows for system wide, or individually programmed, schedules for the rooms in the system. Any other devices with its own programmed schedules are overridden and its menus hidden.

  • Uponor Smatrix Base T-148

    The thermostat is in control of its own room, with restrictions stated above, regarding the Uponor Smatrix Pulse.

Schedule 2

Even if programmed schedules exist in the system, some rooms may still operate without any scheduling. These rooms will operate in constant Comfort mode and is not affected by the programming of other rooms.

Room sensor T-141:

  • Set the value using the Uponor Smatrix Pulse app (requires communication module).

Public thermostat T-143:

  • Set the switch on its back to comfort mode only.

Flush thermostat T-144:

  • Set the switch behind the dial to comfort mode only.

Standard thermostat T-145:

  • Set the switch on its back to comfort mode only.

Digital thermostats T-146 and T-149:

  • Set the ECO setback value in menu 03 to 0.

Digital thermostat T-148:

  • Set the ECO setback value in menu 03 to 0 and menu 00 to Off.

Heating/cooling switch

The heating/cooling switch is manually controlled through the Uponor Smatrix Pulse app (which controls the whole system), an external signal, the supply temperature, or depending on the indoor/outdoor temperature. It is used to switch the operation of the room controller between heating and cooling modes.

A single external signal (if used) can be connected to up to four Base room controllers at the same time, working in parallel. Reducing the number of heating/cooling switches needed in the system.

Install another Uponor Smatrix room controller in the system

Preparation

Error

The room controller will time out after about 10 minutes of inactivity and revert to normal operation. The timer will be reset when a button is pressed or if a device has been registered to it.

Error

Sub room controllers can only be registered to the master room controller.

Error

If a room controller previously connected to a communication module is to be used as a sub room controller (or in a system without a communication module), restore it to sub room controller state by factory reset.

Existing sub room controllers in the system must then either, reset system device channel 01, or register to another master room controller.

Multiple Uponor Smatrix room controllers can be linked together by assigning one room controller to be master and the rest to be sub room controllers.

The master room controller is assigned by connecting it to the communication module (only one room controller can be master in the system), and it can control up to three sub room controllers. Sub room controllers are assigned when registered (in order) to the master room controller.

  • Ensure that all room controllers are powered and that at least one thermostat is registered to each one.

  • Ensure access to all room controllers before starting the registration process.

  • Assign master/sub roles to the room controllers by connecting the communication module to the master room controller.

  • Ensure the sub room controllers are placed witin radio range of the master room controller.

Connect another room controller

Error, enter correct language code

Make sure the room controller is connected to a system bus connector (one of the rightmost connectors) on the room controller. Otherwise the room controllers will be unable to communicate with each other.

Error

Up to four Uponor Smatrix room controllers can be connected in the same system.

Uponor Smatrix room controllers can be connected to each other using daisy chain, direct connection, or using star topology (the star module can be used). A star module can only be used for one bus type at a time. That is, a thermostat cannot be connected to a star module connected to the system bus and vice versa.

Daisy chain connection

The thermostats in the example are connected in series and only one cable needs to be routed from the room controller and slave module (if available).

This method reduces the total length of cable needed in the system.

Direct connection to room controller and slave module

Every thermostat in the example is connected to the room controller and slave module (if available) with its own cable.

Connection to attached star module

The star module is attached to the room controller and slave module (if available) adding extra connection terminals to the system. Each thermostat in the example is connected direct to the room controller, slave module (if available) and star module.

Connection to cable connected star module

The star module is connected to the room controller and/or slave module (if available) with a cable, using two of the extra connection points. Each thermostat in the example is connected direct to the star module, except one that is connected with daisy chain.

Connect communication cable

Connect the communication cable to either the room controller, slave module, and/or star module.

Connect communication cable to room controller system bus

Error, enter correct language code

Make sure the room controller is connected to a system bus connector (one of the rightmost connectors) on the room controller. Otherwise the room controllers will be unable to communicate with each other.

  1. Lead the cables through cable entries on the top of the room controller frame.

  2. Insert two wires (A,B), the - wire is optional and only used in some cases, into a free system connector (one of the rightmost connectors) on the room controller.

  3. Tighten the screws fixing the wires in the connector.

  4. Cut and stow away unused wires.

  2. Set thermostats to the defined operating settings.

  3. Close the covers of the room controller.

  4. Attach thermostats to the wall.

  5. Print and fill in the “Installation report” (separate downloadable document).

  6. Give the printed manuals and all information about the system to the user.

Operate Uponor Smatrix Base Pulse room controller

Principle of operation

The room controller operates the underfloor heating/cooling system according to customer needs. Temperatures can be adjusted with thermostats located in each room, or if installed with the Uponor Smatrix Pulse app (requires communication module).

As soon as the temperature measured at a thermostat is lower (heating mode) or higher (cooling mode) than the setpoint temperature, a demand to change the room temperature is created and sent to the room controller. The room controller will open the actuators according to current operating mode and other settings. Once the set temperature is reached, this information is sent and the actuators are closed.

The system supports different types of cooling methods and is setup in the Uponor Smatrix Pulse app.

Available cooling methods in the Uponor Smatrix Pulse app.

  • Underfloor cooling (UC)

    Cooling in the system is achieved using underfloor loops.

  • Ceiling cooling (CC)

    Cooling in the system is achieved using ceiling cooling (2-pipe or 4-pipe system).

    Select if the system utilizes a 2-pipe or 4-pipe delivery solution for heating/cooling.

    • 2-pipe means one supply temperature to the system at a time (heating or cooling).

      Autoblancing disabled:In rooms where underfloor heating/cooling is allowed. Underfloor cooling and ceiling cooling is both started when the room termperature is about 1 degree below setpoint.

      Autobalancing enabled: Ceiling cooling and underfloor cooling will follow the current cooling demand.

    • 4-pipe means separate independent heating/cooling sources.

      In heating mode:

      The underfloor loops are used when there is a heating demand.

      In cooling mode:

      Underfloor loops and ceiling cooling are used at the same time when there is a cooling demand.

See Uponor Smatrix Pulse app for more information about the individual functions.

Normal operation without optional scheduling ­programs

When the system is running in normal mode:

  • In Heating mode, the actuators are open when room temperatures are lower than the temperatures set on the thermostats.

  • In Cooling mode, the actuators are open when room temperatures are higher than the temperatures set on the thermostats.

    See Uponor Smatrix Pulse app for more information about different cooling configurations.

For more information see, Operate Uponor Smatrix Base thermostats.

Operation with scheduling ­programs

Scheduling programs provide an option to switch selected rooms between Comfort and ECO mode using a 7-day program. This optimises the installation and conserves energy.

The use of scheduling programs requires at least one of:

  • Uponor Smatrix Base T-148 (programmable thermostat)

  • Uponor Smatrix Pulse R-208 (required for mobile app access)

For more information see, Operate Uponor Smatrix Base thermostats.

For more information see, Operate Uponor Smatrix Pulse communication module.

Run mode

During normal operation the room controller is in run mode.

Exit to run mode

If the room controller is in registration or forced mode, exit to run mode by pressing the OK button until the LEDs turn off (about 3 seconds).

Room controller LEDs

If the Uponor Smatrix Pulse app (requires communication module) is not used, it is recommended to occasionally check the power LED on the room controller for alarms. The power LED flashes continuously for general alarms. Determine which thermostats are issuing alarms by removing the cover. If a channel LED is indicating an error, check the function of the registered thermostat.

The room controller power LED is on (green) during normal operation.

All the channel LEDs are off when there is no current or waiting actuator activity. The LEDs turn on when the corresponding actuators are activated or start flashing when they are awaiting activation.

Up to eight actuators in six rooms can be in the opening process at the same time. If a slave module is installed, the LEDs of the seventh and subsequent actuators flash while they are waiting for the previous actuators to be fully open.

Maintenance

Manual preventive maintenance

Error, enter correct language code

Do not use any detergents to clean the Uponor Smatrix components.

The Uponor Smatrix room controller requires no preventive maintenance except cleaning:

  1. Use a dry soft cloth to clean the components.

Automatic preventive maintenance

The Uponor Smatrix room controller is equipped with an automatic exercise function. This function consists of a test run designed to prevent the pump and actuators from seizing up due to inactivity.

This exercise is run every 6 days ±24 hours at random:

  • The pump exercise is only run if the pump has not been run since the last exercise. During the exercise the pump is activated for 3 minutes.

  • The actuator exercise is only run if the actuators have not been operated since the last exercise. The exercise periodically opens and closes the actuators.

If the system includes a communication module, the exercise function can be activated at any time using the Uponor Smatrix Pulse app.

Corrective maintenance

Fallback mode

If a thermostat is malfunctioning or not detected, the room controller executes the fallback mode to maintain the temperature in the room (heating mode only) until the problem is resolved.

Resetting the room controller

If the room controller does not work as expected, for example due to a hang-up, it can be reset to solve the problem:

  1. Disconnect and reconnect the room controller to AC power.

      Connect the communication module to the local network using an Ethernet cable.

      For more information see, 5. Connect the optional ethernet cable.

Room controller alarms/problems

See , for more information about the room controller LED status.

Contact the installer

For installer contact information, see the installation report in the end of this document. Prepare the following information before contacting an installer:

  • Installation report

  • Drawings of the underfloor heating system (if available)

  • List of all alarms, including time and date

Installer instructions

To determine if a problem is caused by the supply system or the control system, loosen the actuators from the manifold for the room concerned, wait a few minutes and check if the flow pipe of the underfloor heating loop becomes warm.

If the pipe does not become warm, the problem is in the heating system. If the loop becomes warm, the cause could be the room control system.

A supply system defect can be indicated by no warm water in the manifold. Check the boiler and circulation pump.
