The communication module has re-established
communication with Uponor cloud services
This alarm will only be received as a push notification and/or SMS (if
activated) to the mobile phone number registered to the customer
account in Uponor cloud services.
• The communication between communication module and
Uponor cloud services is re-established, and the communication
module LED is fixed green.
Software update failed
• The room controller software update has failed.
1. Make sure all sub room controllers are connected to the
master room controller.
2. Restart the room controller (power off and on again).
Contact the installer if the problem persists.
Floor temperature limit reached
• The floor temperature is either too high or too low. This may be
due to:
-
The floor is heated by the sun, or another heat source.
Wait until the floor temperature is lowered.
-
The floor is cooled by a cool draft, or similar. Wait until the
floor temperature is higher.
-
Too high supply temperature to the room. Review the heat
source settings, if applicable.
-
Too low supply temperature to the room. Review the heat
source settings, if applicable.
-
Too high setpoint for the room. Reduce the setpoint.
-
Too low setpoint for the room. Increase the setpoint.
-
Floor temperature limit to low. Increase the limit.
Faulty temperature sensor
• An error has been detected with the internal temperature sensor
in the thermostat.
Replace the thermostat.
Faulty external temperature sensor
• An error has been detected with the external sensor connected
to the thermostat.
-
Make sure the correct thermostat control mode (settings
menu 4) is set in the digital thermostat
-
Check the connection of the external sensor.
-
Disconnect the external sensor and check it with an
ohmmeter. Make sure the value aligns with the
temperatuer sensor diagram.
If the error persists, replace the external sensor.
Faulty relative humidity sensor
Note
RH control is activated in the Uponor Smatrix PULSE
app (requires communication module).
• An error has been detected with the internal relative humidity
sensor in the thermostat.
Replace the thermostat.
Faulty Comfort/ECO switch
• The room controller is having problem communicating with the
system device configured as an external switch.
Force the thermostat to transmit by opening/closing the external
switch.
If the problem persists:
-
Make sure the cable between the room controller and
system device thermostat is connected, or that a wire is
not damaged
-
Replace the system device thermostat if nothing else
works, the system device thermostat is broken
Relative humidity sensor limit
Note
RH control is activated in the Uponor Smatrix PULSE
app (requires communication module).
• The relative humidity limit is reached.
Lower the humidity level by starting a dehumidifier or increasing
the supply temperature setpoint.
Faulty outdoor temperature sensor
• An error has been detected with the outdoor temperature sensor
connected to the public thermostat.
-
Check the connection of the outdoor temperature sensor.
-
Disconnect the external sensor and check it with an
ohmmeter. Make sure the value aligns with the
temperatuer sensor diagram.
If the error persists, replace the external sensor.
Faulty heating/cooling supply sensor
• An error has been detected with the heating/cooling supply
sensor connected to the public thermostat.
-
Check the connection of the heating/cooling supply
sensor.
-
Disconnect the external sensor and check it with an
ohmmeter. Make sure the value aligns with the
temperatuer sensor diagram.
If the error persists, replace the external sensor.
External heating/cooling switch lost
• The room controller is having problem communicating with the
system device configured as an external switch.
Force the thermostat to transmit by opening/closing the external
switch.
If the problem persists:
-
Make sure the cable between the room controller and
system device thermostat is connected, or that a wire is
not damaged
-
Replace the system device thermostat if nothing else
works, the system device thermostat is broken
General systems alarm
• Check the external source connected to the GPI and investigate
why the general systems alarm has tripped.
