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.

Fault clearance
10. Fault clearance
To allow an accurate diagnosis in case of malfunction, the unit is equipped with
a fault display system. The faults are shown on the basic display of the unit in
form of an error code:
Fault overview:
A corresponding fault code is shown alternately in the lower display:
0---°C = Sensor heat supplier (e.g. collector or
solid fuel boiler) has interruption
1---°C = Sensor heat storage tank has short
circuit
1---°C = Sensor heat supplier (e.g. collector or
solid fuel boiler) has short circuit
0---°C = Sensor heat storage tank has
interruption
Fault code Cause Repair
0--- Sensor F1, F2 or F3 interruption Check cable and plug connection; repair
if necessary
1--- Sensor F1, F2 or F3 short circuit Replace sensor
