Connection conditions
The connection of the optional PCB allows temperature control for two heating circuits. Mixing
valves, circulation pumps and temperature sensors for heating circuits 1 and 2 are to be connected
to the corresponding terminals of the optional PCB. The temperatures in the two heating circuits
are controlled mutually independently by the remote controller.
Pumps for heating circuits 1 and 2:
● The cables of the pumps for heating circuits 1 and 2 must each be 2 x min. 1.5 mm²
and conform to the code 60245 IEC 57 or higher.
● Maximum total cable length: 50 m
Solar system:
● The cable of the solar system must be 2 x min. 1.5 mm² and conform to the code
60245 IEC 57 or higher.
● Maximum total cable length: 50 m
Swimming pool pump:
● The cable of the swimming pool pump must be 2 x min. 1.5 mm² and conform to the
code 60245 IEC 57 or higher.
● Maximum total cable length: 50 m
