Installation and Operation Manual

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:
-
The system device thermostat is out of range. T
ry to find a
new position for the system device thermostat and/or the
antenna, or, if possible, move any shielding objects
-
New installations in building shield radio signals (for
example, metal door safe). Try to find a new position for
the system device thermostat and/or the antenna, or, if
possible, move the shielding object
-
Low radio signal detected (sporadic communication with
the connected unit). The transmitter is working with
reduced signal intensity
-
The transmitter in the system device thermostat is faulty.
Replace the thermostat
General systems alarm
• Check the external source connected to the GPI and investigate
why the general systems alarm has tripped.
High supply temperature
This alarm is only shown if Supply diagnostics is running (the function
requires connection to Uponor cloud services).
• The supply temperature is too high.
Check the heat source, or supply temperature controller, to lower
the supply temperature. Contact the installer if the problem
persists.
Low supply temperature
This alarm is only shown if Supply diagnostics is running (the function
requires connection to Uponor cloud services).
• The supply temperature is too low.
Check the heat source, or supply temperature controller, to
increase the supply temperature. Other possible causes may be
too low flow on the supply line, or a malfunctioning circulation
pump. Contact the installer if the problem persists.
Low average temperature
• Average temperature in the system is lower than set limit (se
Installer settings).
The average temperature is calculated using selected rooms
(activated in room settings).
This may be due to one of the following probable causes:
-
Thermostat setpoints are too low. Increase the setpoints
on the thermostats in the rooms where the average
temperature is calculated
-
The supply temperature is too low. Check the heat source,
or supply temperature controller, to increase the supply
temperature. Other possible causes may be too low flow
on the supply line, or a malfunctioning circulation pump.
Contact the installer if the problem persists
-
The average temperature limit is too low. Increase the
average temperature limit
-
Other factors, such as opened windows/doors etc. Close
doors/windows which might af
fect the measured
temperature
Relay module lost
• Communication failure with the relay module.
-
Make sure the relay module is powered on.
-
Register the relay module again to the master room
controller
.
Otherwise contact the installer.
The communication module does not start
• There is not power to the communication module.
1. Check the communication cable between the room
controller and communication module, make sure it is
connected properly.
2. Replace the communication cable if needed.
3. Contact the installer or replace the communication module
Bad Wi-Fi connection
• The communication module looses connection with the Wi-Fi
network.
-
Connect the communication module to the local network
using an Ethernet cable.
For more information see, 5. Connect the optional ethernet
cable, Page 25.
14.6 Room controller alarms/
problems
See Controller LEDs, Page 76, for more information about the room
controller LED status.
The power LED and channel LED on the room
controller flashes
• The antenna is out of position or a wire is disconnected
-
Install the antenna in a correct position with the cable
correctly connected
