General
Systems with heat source and hot water tank are controlled via the differential
temperature control. When the heat source temperature exceeds the tank
temperature by the value set on the controller, the circulation pump is activated
by the control and the heat absorbed in the heat source is transported to the hot
water tank.
Intended use
The unit is manufactured in accordance with state of the art technology and
approved safety regulations. Nevertheless, using the unit can cause danger to the
user or third persons, or damage to the unit and other assets. The unit must be
used exclusively as differential temperature controller.
Safety
All electrical connections, safety measures and protections have to be carried out
by an authorised professional electrician according to the valid standards and VDE-
guidelines, as well as the local regulations. The electrical connection must be a
fixed connection according to VDE 0100.
Hazard symbols in this operating manual
