Chapter 3:

System Description

Smatrix Pulse is a wireless zoning control system designed for radiant heating and cooling installations with the ability to integrate forced-air heating and cooling.

System Overview

The Smatrix Pulse hardware consists of one or multiple controllers, an optional Communication Module, thermostats, actuators, and wireless relays. The Controller manages the operation of the actuators when the thermostats detect a demand for heating and/or cooling.

System optimization and settings (for up to four controllers) is completed through the Smatrix Pulse App (connected via the Communication Module). The system can function without the Communication Module but will reduce the level of system functionality.

Different models of thermostats control heating and cooling operation. Designed for maximum comfort, the thermostats communicate with the controller by radio link. It is possible to mix the different types of Smatrix Pulse thermostats in the same installation.

Wireless relays provide installation flexibility when needing to control other heating and cooling devices when running additional wiring is a challenge.

Actuator Management

Actuator management prevents too many actuators from being open at the same time. This reduces the peak power needs. Reduce peak current by delaying the opening of some actuators (as they use most current while being opened). Up to eight (8) actuators can be opened at the same time. Additional actuators are queued and opened in order.

Autobalancing

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

Smart Home

P P P P P P P

P P P P

Autobalancing is a function where the system calculates the actual energy need of single rooms or zones and adapts the output power of each loop to its length. This means a short loop might get 20% on time while a long loop might get about 60%. The autobalancing continues through the seasons and throughout the changing conditions and usage patterns of the household, removing the need for manual balancing. This gives more even floor temperatures and faster system reaction times with lower energy consumption than standard control systems.

Note

Default for Autobalancing is set to On. Setting this value to Off requires the Communication Module.

Note

Autobalancing can be used in combination with hydronic balancing.

Smart Home Connectivity

Note

Smart home connectivity requires the use of the Communication Module (R-208) and the Uponor Smatrix Pulse App.

Cloud Services

Use the Communication Module to connect to the Uponor Cloud to access system information and settings, including:

• Viewing and adjusting room temperatures

• Setting Home or Away status

• Changing mode of operation (heating/cooling)

• Viewing alarms

• Viewing weather forecast

• Viewing room temperature data (trends)

• Setting up Comfort/ECO profiles and assigning to rooms

• Setting low temperature limits (average)

Comfort and Economy (ECO) Modes

Using the Communication Module and Smatrix Pulse App, it is possible to change the temperature setpoints between two different temperatures. The available modes are Comfort and ECO (economy). Use the Smatrix Pulse App to switch between Comfort and ECO modes and also create a schedule and apply it to one or multiple zones.

Figure 4-1: Comfort and ECO mode examples

Figure 4-1 shows the system delivers heating in Comfort

mode in the morning and late afternoon but enters ECO mode at night and in the middle of the day when the house is normally unoccupied and energy can be conserved.

Caution!

Connecting an external Comfort/ECO switch to the GPI terminals on the Controller will override the time schedules in the Smatrix Pulse App when the switch is closed. This feature will require setup in the app.

Note

Use only one Comfort/ECO switch in the system.

Cooling Operation

The controller can operate underfloor cooling installation based on customer needs. Adjust temperatures with thermostats or by using the Smatrix Pulse App.

As soon as the temperature measured at a thermostat is higher than the setpoint temperature, a demand to cool the room or zone is created and sent to the Controller. The Controller will open the actuators or turn on the cooling terminals on the relay according to the current operating mode and settings. Once the set temperature is reached, the actuators will close, or the air cooling will turn off.

Cooling Options

Use the Smatrix Pulse App to set up the following two cooling methods.

• Underfloor cooling (delivered via hydronic loops in the floor)

• Air cooling (delivered via conventional air conditioning or fan coil units connected to a relay module registered to a room thermostat)

Note

If selecting air cooling as the primary method to cool the room or zone, it is important to turn off the Autobalancing feature.

Cooling – Second Stage

The Smatrix Pulse system can control a second stage of cooling. In rooms where underfloor cooling is installed and a fan coil is also available, underfloor cooling is started when the room temperature rises above setpoint (first stage), and the fan-coil cooling is started or activated depending on how fast the room temperature is increasing. Second-stage cooling will end once the room temperature is at or below the set temperature.

The relay must be registered to a thermostat directly for operation of air-system control. See page 28 for additional information about registering the thermostat to a relay.

Forced Air/Fan Coils

Use the Relay Module (M-263) (part number A3801263) to control air heating and cooling. The air heating and cooling equipment is wired to a relay module and registered (linked) to a thermostat. The operation is dependent on the settings in the Smatrix Pulse App.

Caution!

Limit of four (4) Relay Modules for forced air systems/fan coils per Controller to ensure system performance.

Caution!

When connecting a Relay Module to control air heating or cooling, make sure an actuator is not connected to the first channel the thermostat is assigned to.

12 l Smatrix Pulse | Installation and Operation Manual

Page 14

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 for manual setpoint adjustments when switching between heating and cooling. The offset is 4°F (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 Protection

If the connection to one thermostat or multiple thermostats is lost (i.e., no longer communicating to a Controller), the Controller activates a safety feature for the affected loop(s) and the actuators are run with a set interval to deliver heating to the room or zone. This function deactivates when the thermostat(s) reconnect or unregister from the Controller.

Pump Management

Each controller includes a pump relay to connect a circulation pump. Default operating mode of the circulation pump is set to Individual mode. Use the 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 Primary Controller only or Controller that is connected to the Communication Module. When there is a demand anywhere in the system, the pump wired to the Primary Controller is started.

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

• Relay module (optional): When using the relay module to control a pump, the mode of the pump control is set through in the Smatrix Pulse App.

Relative Humidity/Condensation Control

To avoid condensation when operating underfloor cooling, Uponor recommends measuring the relative humidity (RH) in the rooms. The relative humidity is measured with one or more thermostats.

Cooling is shut off on a per-room or zone basis when the RH limit is reached (set in the Smatrix Pulse App, default 75%). If a dehumidifier is installed, one per 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 Smatrix Pulse App (“dead zone”, default 5%) and has run for a minimum of 30 minutes.

Room Bypass

The system can use up to two rooms (per controller), when in heating mode, as bypass to maintain minimum flow in the system. Rooms can be selected manually or by using the Room Bypass Time Limit function.

Room Bypass Time Limit

The Room Bypass Time Limit function prevents run times shorter than 30 minutes in the system. It does this by analyzing system data (if a room is close to a demand, setpoints, room temperatures, etc.) and chooses suitable rooms to use as bypass.

System Clock

To facilitate accurate log data, scheduling and different timer settings, the Controller receives the correct time and date from Uponor Cloud services. The clock can be set to automatically switch between summer and winter time.

Caution!

Changing operation of the pump control (and/or cooling allowed) in the Smatrix Pulse App will set all relays to Not Configured, and they will need to be reconfigured.

Note

In systems with multiple Controllers (Primary/ sub-configuration), all relays are initially set to Not Configured and require configuration during the installation.

• The Main Floor is registered to Channel 1 but has no actuator(s). This is due to the system controlling forcedair heating and cooling but no radiant. In instances like this, the thermostat needs to be assigned to a channel (in this case, 1) and registered to the relay.

• Bedrooms thermostat is assigned to Channels 2 and 3 and will control actuators connected to 2A, 2B, and 3.

• Family Room heating will open actuators connected to 4 through 6.

• Master Bath heating will open actuators connected to 7.

• Garage thermostat is assigned to Channel 8, but no actuator is connected. The Garage thermostat is also linked to a relay module to operate a zone pump on a call for heating.

Caution!

All thermostats need to be registered to a controller for it to appear in the app

Hardware Handling

• The Primary Controller is the device that is connected to the Communication Module. All others are sub-Controllers.

• A system does not require a Primary Controller, however, system functionality will be limited.

• Sub-Controllers can only be registered to the Primary Controller.

• Relay modules can be registered to both Primary and sub-Controllers.

• The Digital Thermostat (T-169) (part number A3800169) is the only thermostat that can connect to a Relay Module.

• A thermostat can only be linked to one Controller.

• The Controller will time out after 10 minutes of inactivity and revert to normal operation. The timer is reset when a button has been pressed.

• If programmed schedules exist, individual rooms may operate without following a schedule.

• Setting up a system for remote access and connectivity will require a mobile device (e.g., smartphone, tablet, etc.).

A380265C/A380265A Controllers

Controllers are designed for modular installation, meaning the individual parts (Transformer, Controller, Expansion Module, and end cap) easily snap together. However, should the installation require it, the power supply, or Transformer (part number A3850050), can be mounted separately.

Caution!

The Transformer is heavy and might detach if the Controller is held in a vertical position (or upside down) without the cover on.

Caution!

The Expansion Module must be attached by snapping it into place due to connection pins used for connecting to the Controller.

Note

Wires between the Transformer and the Controller must be disconnected prior to detaching the Transformer.

The components can snap on or off without needing to remove the covers or by sliding them into place when the covers are removed.

Thermostats

V1.0

Smatrix Pulse thermostats provide information that is transmitted via wireless signal to Controllers and/or Relay Modules. This information is used to determine whether heating or cooling is needed for the individual zones and operate the appropriate devices.

Use the following instructions for both the Digital Thermostat (T-169) (part number A3800169) and the Mini Sensor (T-161) (part number A3800161).

Placing the Thermostats

• Make sure the thermostat is placed within the room or area(s) it will control.

• Select an indoor wall and a position 5 ft. (1.5 m) above the floor or at eye level.

• Ensure the thermostat is away from direct sunlight and unaffected by solar gain.

• Ensure the thermostat is away from any source of heat (television set, electronic equipment, fireplace, spotlights, etc.).

• Ensure the thermostat is away from any sources of water or excessive humidity.

• Ensure the thermostat is positioned at least 16" (40 cm) away from the Controller to avoid interference.

Labeling the Thermostats

Due to the nature of a completely wireless thermostat, it is easy for thermostats to get placed in the wrong room or zone. Uponor recommends labeling the thermostat during installation to alleviate any confusion. If installing multiple Controllers, include a number reference or location for the specific Controller. This will help once it is time to begin the registration process of linking the thermostats to the correct devices.

Figure 5-8: Breakout tab

Attaching the Thermostat to a Wall

The thermostat packaging includes hardware for the following three attachment options:

• Wall bracket and anchors

• Wall bracket and adhesive strips

• Directly mounting

Figure 5-9: Attach thermostat

Once all the mounting brackets are in place and mounted to the wall, make sure each thermostat is labeled for identification. Be sure to take the thermostats with you. This will make registering them to the Controller(s) an easier process.

Powering Up the Thermostats

Remove the plastic transportation strip from the battery to start the thermostat.

The thermostat uses a single CR2032 3V button cell lithium battery which provides about two (2) years of battery life if it is positioned within radio range of the controller. Ensure that the battery is correctly inserted in the thermostat.

• The Mini Sensor (T-161) (part number A3800161) will perform a self-test for approximately 10 seconds when starting

The Relay Module can be wired to a furnace/air conditioning system or fan coil unit as shown in Figure 6-5 and will require the Communication Module to set up this functionality. The Relay Module outputs provide the following operation:

Heating: The output will turn on (close) for forced air heating in Heating mode when the room temperature linked to the Relay Module falls below its set temperature. Activation will depend on the rate that the temperature is falling. The Relay Module will open once the room temperature reaches the desired set

temperature.

Cooling: The output will close for forcedair cooling in Cooling mode when the room temperature linked to the Relay Module rises above its set temperature. Activation will depend on the rate that the temperature is rising. The Relay Module will open once the room temperature reaches the desired set temperature.

Fan: This output will close when a need for heating or cooling is active on the Relay Module and open when the active function has ended. If recirculation is needed, the fan operation can be set manually through the Smatrix Pulse App.

When the relay module is successfully powered up, the LED will flash red and then turn solid green to indicate normal run mode. The relay LED will turn red when there is an active call for heating and blue for cooling.

Thermostats

The external temperature sensor input can be used to connect a floor temperature sensor on the Digital Thermostat (T-169) (part number A3800169) and Mini Sensor (T-161) (part number A3800161). This sensor can be used to maintain minimum floor temperatures and protect wood flooring. Minimum and maximum values can be set or modified through the Smatrix Pulse App or on the Digital Thermostat if no Communication Module is installed in the system.

Wiring the Floor Sensor (optional)

Caution!

If more than one hour has passed between startup of the thermostat, and the sensor wires are connected, remove the battery from the thermostat, wait 30 seconds, and reinsert the battery again. The thermostat will now be configured with a floor sensor.

• Remove the breakout plastic on the back of the thermostat.

• Press the push buttons on the connection terminals.

• While pressing the push buttons, insert the two wires from the sensor cable (non-polarized) into the connection terminal.

Powering Up the Thermostats

Connecting Wireless Devices

After mounting the hardware and wiring the devices, the next step in the installation is connecting the various devices wirelessly.

With the Smatrix Pulse system, the true wireless features make the hardware more flexible and easier to install. This section will take the user through the various options to “link” the devices together given the following options:

• Linking a thermostat to a Controller

• Linking a thermostat to a Relay Module

• Linking a Controller to a Relay Module

• Linking a sub-Controller to a Primary Controller

LED Guide

LED is unlit and dark (no color)

LED is on solid

LED is alternating colors

Linking a Thermostat to a Controller

It is necessary to link a thermostat to a Controller so the thermostat can pass information to the Controller about room temperatures, set temperatures, etc. The Controller will process the information and make decisions based on the system configuration and mode to operate the various heating and cooling components.

Note

A thermostat can only be linked to a single Controller.

Note

Thermostats must be linked to a Controller for them to appear on the Smatrix Pulse App.

Use the following steps to link a thermostat to a Controller.

• Activate the registration mode by pressing the OK button

on the Controller for three (3) seconds. The Power LED changes from solid green to solid red.

• The Controller is in registration mode when the LED for Channel 1 flashes red. If a thermostat has already been linked, the first channel available will flash red. A previously linked channel will appear solid green.

• If the LED (or channel) flashing is not correct for the actuator the thermostat will control, used the < and > buttons to move the flashing red LED to the preferred channel.

Figure 7-2: Assigning a thermostat

• Press the OK button to enter or assign that thermostat. The link will be confirmed with LED turning solid green, and the next available channel LED will begin to flash red.

• If more than one channel will be assigned to a thermostat, select the next channels to be registered to the thermostat and press OK. Once all selected channel LEDs are solid green, go to the thermostat.

• Put the thermostat into “pairing” or registration mode:

• Digital Thermostat: Press and hold the ▲ and ▼ buttons

on the side of the thermostat until a symbol for an antenna appears in the display. A check will briefly appear when the registration is complete and then revert to current room temperature.

• Mini Sensor: Press the button and hold on the back of

the thermostat for five (5) seconds. The LED on the front of the stat will begin to flash. The LED will turn off when the registration is complete.

• Once the registration between the thermostat and the Controller is complete, the LED (or LEDs) set up previously will turn solid green, and the next available (or open) channel will flash red.

• Repeat these steps for additional thermostats.

Figure 7-3: Pairing the thermostats

Linking a Thermostat to a Relay Module

The A3800169 Digital Thermostat (T-169) can be linked directly to a Relay Module. This can be useful in installations when the thermostat will control a conventional forced-air system with air conditioning or a fan coil or in instances where getting wiring back to the mechanical room for a zone pump in a garage application is an issue. The Relay Module, depending on the system mode, will turn on the relays required for heating and cooling.

1. This will be used to place the Relay Module into pairing

mode or to clear a link or registration to a thermostat

2. This will show the status of the Relay Module based on

the various modes of operation. During power-up, this LED will flash red and green for a short duration. Once the Relay Module is ready for operation, this LED will turn green.

3. During normal operation, a solid red LED will indicate

active operation of the heating equipment and the appropriate Relay Module(s) close. A solid blue LED indicates active cooling.

4. This LED is used during the linking process of the

thermostat to the Relay Module (along with relay to the Controller). This LED has the following states:

• Dark or unlit – Relay Module is not in the linking

(or pairing) mode.

• Slow flashing red – Relay Module is in linking mode.

• Fast flashing red – Relay Module is completing the

linking process with the thermostat.

Note

To change the Relay Module operating mode, power down the Relay Module and wait for 10 seconds. Press and hold the button while restoring power and the LED will flash once (normal).

Note

The thermostat should be linked (or registered) to the Controller first, even though it will not control actuators. See the previous step for Linking a Thermostat to a Controller.

Before proceeding to linking the devices, familiarize yourself with the various items on the Relay Module and their status/operation:

Figure 7-4: Relay Module status items

28 l Smatrix Pulse | Installation and Operation Manual

Page 27

Use the following steps to link a thermostat to a Relay Module:

• Ensure the Relay Module is powered up and the LED is on.

• Activate the registration mode on the Relay Module by pressing the button for three (3) seconds. When done correctly, the linking LED will begin to slow flash red.

Caution!

If no button on the thermostat is pressed for about eight (8) seconds, while in a sub menu, the current values will be saved, and the software exits to the Settings Menu. After 60 seconds, the Relay Module will return to normal run mode.

• Enter the configuration mode on the Digital Thermostat by pressing and holding the middle button for about three (3) seconds.

Figure 7-5: Press and hold middle button for three (3) seconds

• Once the menu is activated, press the up (or top) button until 09 is shown in the top right corner.

seconds.

Linking a Relay Module to a Controller

A Relay Module can directly link to a Controller. Each Controller can only have one Relay Module linked to it to mirror or duplicate the pump and boiler outputs. This can be useful in installations when getting wiring back to the mechanical room for a zone pump and/or boiler is an issue in retrofit or remodel applications.

Caution!

When linking a Relay Module to a Controller and using the “second layer” of pairing, other Controllers will pair to Channel 1 and the Relay Module will pair to Channel 2.

Use the following steps to link or register a Relay Module to a Controller:

• Enter the pairing mode. Press and hold the OK button on the Controller until the LED for the first available channel begins to flash Red.

• Using the < or > buttons, move the flashing LED from the channels to the power LED on the Controller. The LED will begin to flash red. This secondary layer is for linking Relay Modules and other controls to Controllers.

• Press the OK button and the LED for Channel 1 will begin to flash red.

• If done correctly, the LED for Channel 1 will begin to flash red and the power LED will start flashing in a pattern (long flash, short unlit flash, long flash, etc.).

• Press the > button to move the flashing red LED to Channel 2.

Figure 7-9: Enter pairing mode

uponor.com l 29

Page 28

Note

The Relay Module will only link to Channel 2 on Controllers.

• Select (or lock) the channel by pressing the OK button.

The LED should begin to flash green.

• Make sure the Relay Module is powered up and the power LED (2) is on solid green.

• Activate the registration mode on the Relay Module by pressing the registration button (1) for three (3) seconds. When done correctly, the link LED (4) will begin to slow flash red.

• The link LED (4) on the Relay Module will begin to begin flashing faster, and the LED for Channel 2 on the Controller will turn to solid green. At this time, the Relay Module is paired with the Controller.

• Press and hold the OK button to exit pairing mode. When done correctly, the power LED will be solid green.

To link a sub-Controller to a Primary Controller, use the following steps:

• Enter the pairing mode on the Primary Controller (one connected to the Communication Module). Press and hold the OK button on the Controller until the LED for the first available channel begins to flash red.

• Using the < or > buttons, move the flashing LED from the channels to the power LED on the Controller and it will begin to flash red.

• Press the OK button.

• If done correctly, the LED for Channel 1 will begin to flash red, and the power LED will start flashing in a pattern (long flash, short flash, long flash, etc.).

• Repeat the steps for the sub-Controller to be paired with Primary Controller.

• Enter the pairing mode on the sub-Controller. Press and hold the OK button on the Controller until the LED for the first available channel begins to flash red.

• Using the < or > buttons, move the flashing LED from the channels to the power LED on the Controller, and it will begin to flash red.

Figure 7-10: Relay Module status items

Linking a Controller to a Sub-Controller

When multiple Controllers are installed in a system, only one can be connected to a Communication Module. This unit is considered the Primary Controller. All other Controllers will connect to Antennas and are considered sub-Controllers.

Caution!

For thermostat information to appear on the Smatrix Pulse App or for Over The Air (OTA) updates to be installed and updated, all subControllers will need to be linked to the Primary Controller.

Caution!

The 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.

Caution!

If a Controller has been connected to a Communication Module, disconnect the Communication Module, and restore it to the sub-Controller state by performing a factory reset. Existing sub-Controllers in the system must then either reset system device Channel 01 or register to another Primary Controller.

Page 31

Chapter 9:

System Operation

The Controller operates the underfloor heating/cooling installation according to customer needs. The user adjusts temperatures via thermostats located in each room, or if installed with the Smatrix Pulse App (which requires a Communication Module).

As soon as the temperature measured at a thermostat is lower (heating mode) or higher (cooling mode) than the setpoint temperature, it creates a demand to the Controller to change the room temperature. The Controller opens the actuators according to current operating mode and other settings. Once the thermostats signal that the set temperature is reached, this information is sent to the Controller, and the actuators are closed.

The system supports different types of cooling methods and is setup in the Smatrix Pulse App. Available cooling methods in the Smatrix Pulse App include:

• Underfloor cooling via hydronic radiant loops

• Fan coils or conventional forced-air heating and cooling equipment (connected to a relay module registered to a room thermostat)

Note

Be sure to disable Autobalancing (in Installer Settings) when air cooling or heating is installed and configured.

In rooms where radiant cooling is allowed and a fan coil is installed, radiant cooling is activated depending on the rate the temperature is rising in the room. Second-stage cooling (if installed) will activate based on the rate the room temperature is rising.

Refer to the Smatrix Pulse App for more information about these individual functions.

Operation with Schedules

Scheduling programs provide an option to switch selected rooms between Comfort and ECO mode using a 7-day program. This optimizes the installation and conserves energy. When in the comfort mode, the rooms / thermostats will control room temperature based on the user defined set temperature. When in ECO mode, all zones or thermostats that are attached or assigned to a schedule, the set temperature will change based on the offset value, or ECO setback.

For example, if the ECO setback is set to 5, and the Comfort set temperature is 68°F, the new room temperature the system will control to is 63°F (68 – 5 = 63°F). In cooling mode, the ECO setback would be added to the cooling room set temperature.

Note

The Communication Module is required to access the Smatrix Pulse App to create and adjust schedules.

Controller LED Status

If not using the Smatrix Pulse App, Uponor recommends occasionally checking the power LED on the Controller for system status and 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 and batteries of the registered thermostat.

Refer to the following information to determine the LED status of the power (A) and channel LEDs (B) depending on the mode of operation.

Normal Operation without using Schedules

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.

Note

If autobalancing is enabled, actuators could be closed during a demand.

Maintenance

Replacing Batteries

The Digital Thermostat (T-169) and Mini Sensor (T-161) both use a CR2032V battery to power the display, LED, and wireless communication. These batteries will need to be replaced throughout the life of the Smatrix Pulse system.

• The Digital Thermostat (T-169) will need a new battery when the low-battery icon appears on the display. This will also be displayed in the app.

• The Mini Sensor (T-161) will need a new battery when the LED flashes once every two hours. This will also be displayed in the app.

To replace the batteries:

1. Remove the thermostat from the wall.

2. On the back of the thermostat, there is a slot above

the battery compartment to use a pointed object (pen, screwdriver, etc.) to remove the battery.

3. Replace the battery. Insert the new battery with

the + side facing the back of the thermostat.

Software Updates

Users will be notified when an update is available through the Smatrix Pulse App. This may include system enhancements, app updates, or minor bug fixes. To ensure the highest level of operation, updates should be accepted and installed in a timely manner. History has shown that a high percentage of technical support calls could have been averted if the updates were accepted and installed. This only applies to systems that are connected to the Uponor Cloud, have internet access, and have an account created.

Caution!

It is important that all Controllers are operating with the same version of software. Open the Smatrix Pulse App and click the menu icon (three horizontal lines). Then, select System Settings, and then select System Information.

New versions of software will automatically download when available using Over The Air (OTA) updates. This file will download to the main controller (connected to the Communication Module) and distribute this to other controllers without interrupting system operation. Once the update is fully downloaded to all devices, the user/ owner will receive a prompt on the app asking to install the update. Once this is accepted, installing the update will interrupt system operation for 5-10 minutes. Once completed, the system will return to normal operation based on the last mode (heating or cooling).

Alarms

If an alarm is triggered, it will be shown as an alert in the Smatrix Pulse App. Information about the alarm and possible solutions are presented in the app. If connected to Uponor Cloud services, the mobile phone will also receive the alarm as a push notification. Also see Chapter 12: Troubleshooting for additional information.
