relay. If you would like to operate an old boiler or any other
device that has no connection points for thermostats, then
the
1
(NO) and
2
(COM) connection points of the thermostat
should be connected to the mains cable of the device, simi-
larly as a switch would be connected.
To avoid electric shocks, replace the inner cover
removed to connect the wires after installation.
ATTENTION!
Always consider the loadability of the receiver
unit and follow the manufacturer’s instructions of the heating
or cooling equipment. The device must be installed and connected by a
qualified professional! The voltage appearing at terminals 1 (NO) and 2 (COM)
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.
