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 con-
nected to the corresponding terminals of the optional additional PCB. The temperatures in the
two heating circuits are controlled mutually independently by the operating unit.
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 mm
2
and conform to the code 60245 IEC 57 or higher.
● Maximum total cable length: 50 m
Solar station:
● The cable of the solar station 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
