6.2 Relays for Pump and Boiler Control
Activate Relay mode on CF-MC Master Controller (fig. 20):
• Use the menu selection button to select the Relay mode. Relay LED flashes.
• Activate Relay mode by pressing OK . Relay LED goes ON.
Select the Relay configuration (fig. 20/22):
• Press the output selection button and toggle between the possible Relay configurations -
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 configuration 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 configurations 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 (fig. 20):
• Use the menu selection button to select the Input mode. Input LED flashes.
• Activate Input mode by pressing OK . Input LED goes ON.
Select the Input configuration (fig. 20/21/22):
• Press the output selection button and toggle between the possible Input configurations
- 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 (fig. 2 - ).
• 3 LEDs: The CF-MC Master Controller will switch to a fixed set room temperature at 8 °C for
all Room Thermostats when the input for away function is activated (fig. 2 - ).
• 4 LEDs: The CF-MC Master Controller will switch to cooling mode when the input for
heating/cooling is activated (fig. 2 - ). In heating mode the CF-MC Master Controller will
switch to a fixed set room temperature at 8 °C for all Room Thermostats when the input for
away unction is activated (fig. 2 - ) (default).
• Activate selected input configuration by pressing OK .
6.4 Heating/Cooling
A 2-pipe system can be configured for automatic heating/cooling change-over.
• A PT-1000 pipe sensor must be connected to the PT-1000 input (fig. 2 - ).
• Configuration 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 configured separately!
Activate Relay mode on CF-MC Master Controller 2/3 (fig. 20):
• Use the menu selection button to select the Relay mode. Relay LED flashes.
• Activate Relay mode by pressing OK . Relay LED goes ON.
Select the Relay configuration (fig. 20/22):
• Press the output selection button and toggle between the possible Relay configurations -
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 configuration by pressing OK .
6.6 Wireless relay
CF-WR Wireless Relay can be connected to the CF-MC Master Controller and configured by the CF-RC
Remote Controller (see separate instruction).
