Installation
Low voltage max. 12VAC/DC connection
in the left-hand terminal compartment!
Terminal: Connection for:
S1 (2x) Sensor 1 collector
S2 (2x) Sensor 2 storage tank low
S3 (2x) Sensor 3 storage tank top
The polarity of the sensors is freely se-
lectable.
Mains voltages 230VAC 50-60Hz Con-
nection in the right-hand terminal com-
partment!
Terminal: Connection for:
