Changing default display temperature:
•The actual room temperature is shown in the display as default.
•To change default display from actual room temperature to actual oor surface temperature,
press and hold the push button until SET MAX is shown in the display.
•Press the button
shortly and repeatedly until or is ashing in the display.
•Press the up/down selector to select the new default display temperature:
Room temperature Floor surface temperature.
Setting of room temperature:
•Make sure actual room temperature is shown in the display.
•Press the up/down selector to set the desired room temperature value. SET is shown in the
display.
•When releasing the up/down selector the display returns to actual temperature.
Note! The thermostat regulates the oor heating system according to room temperature set point, within
the maximum and minimum limitations dened for the oor surface temperature.
Room temperature limitation:
•Make sure actual room temperature is shown in the display.
•Press the push button until SET MAX is shown in the display.
•Press the up/down selector to set the maximum room temperature limitation.
•Press the push button shortly, SET MIN is shown in the display.
•Press the up/down selector to set the minimum room temperature limitation.
•Press the push button shortly and the actual oor surface temperature is shown in the
display.
Floor surface temperature limitation (only valid for CF-RF):
•Ensure actual oor surface temperature is shown in the display illustrated by
.
•Press and hold the push button until SET MAX is also shown in the display.
•Press the up/down selector to set the maximum oor surface temperature limitation.
•Press the push button shortly, SET MIN is also shown in the display.
•Press the up/down selector to set the minimum oor surface temperature limitation.
IMPORTANT!
As heat emission from the oor may vary slightly depending on oor covering - and thereby cause inaccu-
rate temperature measurement - it may be necessary to adjust the setting of max. and min. oor surface
temperatures accordingly. It is important always to follow recommendations from the oor manufacturer
regarding max. oor surface temperature. It is recommended to include mixing shunt for oor heating
circuits in order to ensure optimal ow temperature. - In addition to minimised energy consumption, cor-
rect setting of the ow temperature will eliminate the risk of excessive heat transfer to the oor.
6. Conguration
6.1 Actuator Outputs
Activate Output mode on CF-MC Master Controller (g. 20/22):
•Use the menu selection button
to select the Output mode. Output LED ashes.
•Activate Output mode by pressing OK . Output LED goes ON.
Select the output conguration:
•Press the output selection button and toggle between the possible output congurations
- the output LEDs will be ON – indicated below:
•1 LED: The outputs are congured to NC actuators with ON/OFF regulation.
•2 LEDs: The outputs are congured to NO actuators with ON/OFF regulation.
•3 LEDs: The outputs are congured to NC actuators with Pulse Width Modulation (PWM)
regulation for oor heating (default).
•4 LEDs: The outputs are congured to NO actuators with Pulse Width Modulation (PWM)
regulation for oor heating.
•5 LEDs: A Remote Controller is installed, and it is not possible to change settings from the
CF-MC Master Controller.
•Activate selected output conguration by pressing OK .
Note! During periods with no output activations the CF-MC Master Controller will run a valve motion
program every 2 weeks and it will last for up to 12 minutes. Individual output conguration is possible with
the CF-RC Remote Controller, see separate instruction.
