General

Systems with 2 heat sources and hot water tanks 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 VDE­guidelines, as well as the local regulations. The electrical connection must be a
fixed connection according to VDE 0100.
