•The output relay of the thermostat has three potential-free
connection points, i.e. No. 1 (NO); No. 2 (COM) and No. 3 (NC),
which are located under an inner cover on the inner side of the rear
panel. To control heating, connect the two connection wires of the
device to be controlled to terminals No. 1 (NO) and No. 2 (COM), i.e.
to the normally open terminals of the relay, while the two connection
wires of the cooling equipment should be connected to terminals
No. 2 (COM) and No. 3 (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.
ATTENTION! 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.
