Instruction CF-MC Master Controller
5.4 Input for Heating & Cooling
• Connect the two wires from an external switch (ON/OFF) to the two
terminals for the heating and cooling input. (fig. 15)
When this switch is closed (ON) the system will switch from heating to
cooling mode.
• Fix the cable. (fig. 16)
Note #1: When the system is in cooling mode the actuator output will be
activated (ON when NC actuators / OFF when NO actuators) when the
temperature in a room exceeds the set point.
Note #2: When the system is in cooling mode an independent dew-point
alarm function should be installed.
Danfoss offers the below listed components (see example fig. 17)
EDA-4V: Electronic dew-point alarm - 088H001
EDA-S: Dew-point sensor - 088H011
