Relay Wiring

1(NC),2(COM),3(NO)

Heating: connect the two connection wires of the device to be controlled to terminals No. 3 (NO) and No. 2 (COM), i.e. to the normally open terminals of the relay

Cooling: the two connection wires of the cooling equipment should be connected to terminals No. 2 (COM) and No. 1 (NC), i.e. to the normally closed terminals of the relay.

• To prevent electric shock, replace the inner cover removed for the connection of wires after the assembling process has been completed.

The device must be installed and connected by a qualified professional. Always follow the manufacturer's instructions when connecting the thermostat to any heating or cooling appliance.

The voltage appearing at terminal No. 1, No. 2 or No. 3 depends only on the system being controlled, therefore the dimensions of the wire are determined by the type of the device to be controlled. The length of the wire is of no significance.
