RECEIVER WIRING DIAGRAM
The operation of connecting the receiver unit with 230 V power supply andcentral heating system must be
performed only by qualified personnel and only after consulting the thermostat andboiler documentation.
The receiver unit has two relay type controls (COM-NO-NC / Normal Open and Normal Closed) without
potential (non-energized). Each relayexecutes the closing/openingof a control circuit with a maximum current
of 10 A, and maximum voltage of 250 V AC / DC .
So if the heating system is designed with 2 hydraulically separated zones with 2 pumps / solenoid valves
or even 2 boilers, you can separately control the heating of each zone (pumps / solenoid valves / boilers)
separately with the help of this thermostat with 2 monitoring / control units. Find examples of connection
with pumps / solenoid valves or certain models of thermal power plants thermal power plants at the end of
the manual. Find examples of connections with certain models of Gas boiler Systems at the end of the user
manual.

* The installation must be done only by the authorized installer and only after consulting the manuals, and
checking the connections and their compatibility.
