Important note
The maximum permitted current associated with the supply voltage from the
HRC3.1/HRC3.2 room controller must not be exceeded.
(For further information, see data sheet CM2N6313 and CM2N6314.)
Addressing
The room temperature control algorithm is not in the room unit itself, but in the
controller application. To enable the room controller to communicate with the room unit,
the latter must be assigned with an address.
The addresses of the room operator units are set by DIP switch on the back of the
room comfort operator unit.
