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 VDE-
guidelines, as well as the local regulations. The electrical connection must be a
fixed connection according to VDE 0100.

9. 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:
Use + / - to switch to:
Fault overview:
A corresponding fault code is shown alternately in the lower display:
1 = Display 1
0---°C = Sensor F3 Heat supplier 1 (z.B. collector1,
solid fuel boiler1) is interrupted
1---°C = Sensor F1 heat storage tank 1 has short
circuit
2 = Display 2
1---°C = Sensor F4 Heat supplier 2 (e.g.
collector2, solid fuel boiler2) has short
circuit
0---°C = Sensor F2 (option) heat storage tank 2 is
interrupted
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
Fault Cause Repair
Display text not visible No power, defective fuse in unit Check cable and plug connection;
repair if necessary; replace fuse
Fault code Cause Repair
11-0 Interruption sensor F1 Check cable and plug connection;
replace if necessary
11-1 Short circuit sensor F1 Replace tank sensor
12-0 Interruption sensor F2 See 11-0
12-1 Short circuit sensor F2 See 11-1
13-0 Interruption sensor F3 See 11-0
