Installation Guide CF-MC Master ControllerDanfoss Heating Solutions VIUHK902 01/201696.2 Relays for Pump and Boiler ControlActivate 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 3rdday 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 CoolingActivate 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 forall 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 forheating/cooling is activated (fig. 2 - ). In heating mode the CF-MC Master Controller willswitch to a fixed set room temperature at 8 °C for all Room Thermostats when the input foraway unction is activated (fig. 2 - ) (default).• Activate selected input configuration by pressing OK .6.4 Heating/CoolingA 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 ControllersIf more CF-MC Master Controllers are connected to CF-MC Master Controller 1 in one system, theirrelays 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 relayCF-WR Wireless Relay can be connected to the CF-MC Master Controller and configured by the CF-RCRemote Controller (see separate instruction).GB
