RECEIVER WIRING DIAGRAM
The operation of connecting the receiver unit with 230 V power supply and central heating system must be
performed only by qualified personnel and only after consulting the thermostat and boiler documentation.
The receiver unit has two relay type controls (COM-NO-NC/Normal Open and Normal Closed) without potential
(non-energized). Each relay executes the closing/openingo f 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.
