17 Troubleshooting
17.1 General
This section describes general problems and alarms that can occur
with the Uponor Smatrix system and describes solutions. A common
cause of a problem though may be due to wrongly installed loops or
mixed up thermostats.
Fluctuating floor temperature
Floor temperature is changing abnormally between
hot and cold in heating mode
• Supply water temperature is too high
-
Check boiler or shunt
-
Run supply diagnostic test in the Uponor Smatrix PULSE
app (requires communication module)
Room temperature does not match setpoint on
thermostat, and actuators shut on/off on a fixed
interval
• Heating fallback function is activated due to lost communication
with thermostat
-
Check the connection of the room thermostat
-
Check batteries in room thermostat
-
Check the Uponor Smatrix PULSE app (requires
communication module) for an error indicating that a
thermostat has lost connection
-
Reconnect if the connection is lost
Room temperature does not match setpoint on
thermostat
• The thermostat is placed in direct sunlight or close to other heat
sources
-
Check placement of the thermostat according to
installation instructions and change location if needed
• The thermostat is placed in the wrong room.
-
Check the placement of the thermostats and change
rooms if needed.
The room is too cold (or too warm in cooling
mode)
Thermostat setpoint is too low
• The thermostat setting is too low
-
Change the temperature setpoint
-
Use maximum and minimum settings in the Uponor
Smatrix PULSE app (requires communication module) to
protect the system from consequences of unreasonable
temperature settings
The temperature displayed on the thermostat
changes after the thermostat is moved
• The thermostat may be influenced by an external heat source
-
Change location of the thermostat
Installation report and room controller/channel
numbering on the thermostat label doesn't match
• The thermostats of individual rooms are incorrectly registered
-
Place the thermostat in the correct room or change the
thermostat registration in the room controller
Installation report and room controller/channel
numbering on the thermostatic head label doesn't
match
• The thermostatic heads of individual rooms are incorrectly
registered/installed
-
Place the thermostatic head in the correct room or change
its registration on the room controller
White indicator cannot be seen in window of an
actuator
• An actuator does not open
-
Replace the actuator
-
Contact the installer
Setpoint temperature displayed in the room
information menu is lower than the temperature set
on the thermostat
• Incorrect minimum/maximum limitation
-
Change the minimum/maximum limitation in the Uponor
Smatrix PULSE app (requires communication module)
ECO mode
• ECO in room information menu
-
Change ECO profile or assign another profile to the room
in the Uponor Smatrix PULSE app (requires
communication module)
-
Reduce the ECO setback value for the thermostat
The room is too warm (or too cold in cooling
mode)
Corresponding loop is warm even after a long
period without heat call
• An actuator does not close
-
Contact the installer
-
Check that the actuator is correctly installed
-
Replace the actuator
• The actuator may still be in its initial factory default position
(open).
-
Adjust setpoint temporarily to maximum setting so the
acutators fully open (channel LED is red), to deactivate the
default position.
The floor is cold
The room temperature OK but the floor is cold
• No heat demand from the underfloor heating system
• The room is heated by another heat source
