When connecting solar panels, the PT-1000

sensor (S01) as a collector sensor and a

PT-1000 sensor (S02) as a lower storage tank

sensor must be used.

n

All sensors are to be connected to the indoor-

module switching-cabinet according to the ter-

minal-assignment diagram.

Contact sensor

Contact sensors can be mounted on the pipes, to

measure the heating-circuit temperatures, for

example.

n

The contact sensor is fastened to a pipe with

the trapezoidal brackets and retaining strap

provided.

n

Clean the mounting point on the pipe. Subse-

quently a thermal compound (A) is applied and

the sensor is fixed in position.

If the sensor cables are too short, they can be

extended up to a maximum of 100m with wire

having a cross-section of 1.5 mm².

External sensor

The connection of an outdoor sensor is always

required for the heat pump manager.

n

Mount the outdoor sensor pointing skyward, in

a north-easterly direction, about 2.5 metres

above the ground. It may not be subjected to

direct sunlight and is to be protected against

excessive wind. Installation above windows or

air ducts is to be avoided.

n

In order to carry out the installation, remove the

cover and secure the sensor with the screws

provided.

A cable with wire cross-sections of 0.5 mm² is

recommended for connecting the sensor.
