Installation Guide CF-MC Master Controller
6.2 Relays for Pump and Boiler Control
Activate Relay mode on CF-MC Master Controller ( g. 20):
• U se the menu selection button
•
Activate Relay mode by pressing OK
Select the Relay con guration ( g. 20/22):
•
Press the output selection button
the output LEDs will be ON – indicated below:
•
NO LEDs: The relays are not used.
•
1 LED: Pump control.
•
2 LEDs: Boiler control.
•
3 LEDs: Pump and boiler control.
•
4 LEDs: Pump control with 2 min. start/stop delay.
•
5 LEDs: Pump and boiler control, with 2 min. start/stop delay on pump (default).
•
Activate selected relay con guration by pressing OK .
Note! If the pump relay is active, the CF-MC Master Controller will run a pump motion program every 3rd
day and it will last for one minute.
More relay con gurations can be made via the CF-RC Remote Controller (see separate instruction).
6.3 Input for Away Function and Heating and Cooling
Activate Input mode on CF-MC Master Controller ( g. 20):
•
Use the menu selection button
•
Activate Input mode by pressing OK . Input LED
Select the Input con guration ( g. 20/21/22):
•
Press the output selection button
- the output LEDs will be ON – indicated below:
•
1 LED: The input ports are not used.
• 2 LEDs: The CF-MC Master Controller will switch to cooling mode when the input for heating/
cooling is activated ( g. 2 - ).
•
3 LEDs: The CF-MC Master Controller will switch to a xed set room temperature at 8 °C for
all Room Thermostats when the input for away function is activated ( g. 2 -
•
4 LEDs: The CF-MC Master Controller will switch to cooling mode when the input for
heating/cooling is activated ( g. 2 - ). In heating mode the CF-MC Master Controller will
switch to a xed set room temperature at 8 °C for all Room Thermostats when the input for
away unction is activated ( g. 2 -
• A ctivate selected input con guration by pressing OK .

6.4 Heating/Cooling

A 2-pipe system can be con gured for automatic heating/cooling change-over.
•
A PT-1000 pipe sensor must be connected to the PT-1000 input ( g. 2 -
•
Con guration is only possible via CF-RC Remote Controller (see separate instruction).
6.5 Relays on more (2 to 3) CF-MC Master Controllers
If more CF-MC Master Controllers are connected to CF-MC Master Controller 1 in one system, their
relays for pump and boiler control should be con gured separately!
Activate Relay mode on CF-MC Master Controller 2/3 ( g. 20):
•
Use the menu selection button
•
Activate Relay mode by pressing OK . Relay LED
Select the Relay con guration ( g. 20/22):
• P ress the output selection button
the output LEDs will be ON – indicated below:
Uses pump and boiler connected to CF-MC Master Controller 1:
•
NO LEDs: The relays are not used (default).
If local manifold and pump are separate:
•
1 LED: Pump control.
• 4 LEDs: Pump control with 2 min. start/stop delay.
•
Activate selected relay con guration by pressing OK .

6.6 Wireless relay

CF-WR Wireless Relay can be connected to the CF-MC Master Controller and con gured by the CF-RC
Remote Controller (see separate instruction).
