10.4.3 Connection of control sensor
The control sensor is connected to terminal F1 in the heat
pump‘s terminal box. Control sensor F1 is installed in the
DHW tank in the supplied sensor pocket.
Material damage
Never apply voltage to the sensor terminals. This
would irreparably damage the heat pump! OCHS-
NER accepts no liability for this.
WARNING: Electrocution
Connection work which requires junction boxes to
be opened must be carried out by an authorised
contractor, as there is a risk to life when working
on live components!
