4 x Installation

4.2.3 Installing temperature sensor

1. Bend over the contact springs on both sensors (return

temperature sensor, storage tank temperature sensor) and

insert into the sensor tube.

2. Position the return flow temperature sensor in the sensor tube

at approx. 130 cm insertion depth (cable tie).

3. Position the storage cylinder temperature sensor in the

sensor tube at approx. 70 cm insertion depth (cable tie).

4. Push the sealing plug into the well, and run the cables.

4.2.4 Preparing and fitting the control system

Requirements

– For electrical connections and consumable electrical materi-

als (cable, insulation, etc.), follow all valid country-specific

guidelines.

– For every fixed mains connection, use a separate

EN 60335-1 disconnector for all-pole disconnection from the

power mains and a GFCI circuit breaker with a reaction time

≤ 0.2 s.

Permissible cable types at the terminal strip:

– Single core ≤ 2.5 mm

– Multi-core ≤ 2.5 mm

– Multi-core with wire end sleeves with insulating collar

≤ 1.5 mm

– Multi-core with wire end sleeves without insulating collar

≤ 2.5 mm

CAUTION!

On no account may the storage cylinder temperature

sensor of the boiler controller be inserted more than

75 cm into the sensor well. A sensor that is inserted

too deeply can lead to overheating of the consumption

water section, as well as a "hang-up" of the control unit

during the storage cylinder charging phase.
