11 Trouble shooting
The table below shows problems and alarms that can occur with the Climate Controller C-46 and descibes solutions.
Alarms are indicated by a flashing alarm indicator and a warinig sign on the display.
Problem Cause Actions
Alarm: Missing sensor Sensor not defined in controller 1. Check in quick menu that the sensor is defined.
Rerun the installation wizard if the sensor is missing.
Wired sensor is not correctly connected
to controller
1. Check the sensor connection.
Radio thermostat is not linked 1. Check the link with the View link function.
2. If link is missing, then connect the thermostat with
the Add link function.
Radio thermostat connected through
Controller C-56 Radio missing
1. Check the ID of the thermostat in the Zones menu.
2. Check the cable connection between Climate
Controller C-46 and Controller C-56 Radio.
3. Check the thermostat linking in Controller C-56
Radio.
4. Check software version of Controller C-56 Radio. It
must be version 5.0.3 or
Mixer valve does not open Actuator is not correctly connected to
controller
1. Check the actuator connection.
Wrong actuator type 1. Thermal actuator: Check that actuator is 24 V DC,
NC.
Motorized actuator is not correctly
configurated
1. Check the external power to the actuator.
2. Check that the rotation setting is correct, clockwise
or counterclockwise.
Other problem 1. Check if mixing valve and source are OK by
removing the actuator and opening the valve
manually.
2. Check all pumps in the system.
Climate Controller C-46 does not
connect with Controller C-56 Radio
Old software version in Controller C-56
Radio
1. Update the Controller C-56 Radio software to
version 5.0.3 or later.
Controller C-56 Radio is not correctly
connected to Climate Controller C-46
1. Check the connection.
Unreasonable readings from wired
sensor
Wrong sensor type connected 1. Check sensor type, only Uponor sensors work with
the controller.
The control is erratic and the
actuator works too often.
Parameter setting is not ideal 1. Decrease the Proportional coeff. parameter, see
section 8.9.2
Control response, page 32.
2. If a motorised actuator is used, increase the Dead
zone parameter, see section 8.6.7
Dehumidifier
control, page 29.
The room temperature is adjusted
slowly when weather conditions
change.
The control system is slow. 1. Increase the Proportional coeff. parameter, see
section 8.9.2
Control response, page 32.
The last couple of degrees takes a
long time to adjust in the room.
Parameter setting is not ideal 1. Decrease the Integration time parameter, see
section 8.9.2
Control response, page 32.
2. If a motorised actuator is used, decrease the Dead
zone parameter, see section 8.6.7
Dehumidifier
control, page 29.
