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 floor 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 flashing 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 floor heating system according to room temperature set point, within
the maximum and minimum limitations defined for the floor 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 floor surface temperature is shown in the
display.
Floor surface temperature limitation (only valid for CF-RF):
• Ensure actual floor 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 floor 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 floor surface temperature limitation.
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 to select the Output mode. Output LED flashes.
• Activate Output mode by pressing OK . Output LED goes ON.
Select the output configuration:
• Press the output selection button and toggle between the possible output configurations
- 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.
