Note! The thermostat regulates the floor heating system according to room temperature set point, within
the maximum and minimum limitations defined for the floor surface temperature.
Room temperature limitation:

• Press and hold the push button
• Press the up/down selector
• Press the push button

IMPORTANT!
As heat emission from the floor may vary slightly depending on floor covering - and thereby cause inaccu-
rate temperature measurement - it may be necessary to adjust the setting of max. and min. floor surface
temperatures accordingly. It is important always to follow recommendations from the floor manufacturer
regarding max. floor surface temperature. It is recommended to include mixing shunt for floor heating
circuits in order to ensure optimal flow temperature. - In addition to minimised energy consumption, cor-
rect setting of the flow temperature will eliminate the risk of excessive heat transfer to the floor.

6. Configuration

6.1 Actuator Outputs

Activate Output mode on CF-MC Master Controller (fig. 20/22):
• Use the menu selection button
• Activate Output mode by pressing OK
Select the output configuration:
• Press the output selection button
- the output LEDs will be ON – indicated below:
•
1 LED: The outputs are configured to NC actuators with ON/OFF regulation.
• 2 LEDs: The outputs are configured to NO actuators with ON/OFF regulation.
• 3 LEDs: The outputs are configured to NC actuators with Pulse Width Modulation (PWM)
regulation for floor heating (default).
• 4 LEDs: The outputs are configured to NO actuators with Pulse Width Modulation (PWM)
regulation for floor 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 configuration 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 configuration is possible with
the CF-RC Remote Controller, see separate instruction.
