n
Follow the connection schematic and the circuit
diagrams (
Chapter 2.6 ‘Terminal block / key’
n
When connecting the control cable, make sure
that polarity is correct.
n
If the outdoor module is installed on a roof, it
and the supporting structure must be earthed
separately (connection to lightning conductors
or foundation earth/ground feature).
Temperature sensors
n
The number of sensors required can vary with
the type of system.
n
Observe the pertinent notes for the sensor
position found in the hydraulic schematic.
n
The standard scope of delivery includes the
outdoor sensors (S10), an immersion sensor
(provided for use as a domestic hot water
sensor - (S08).
n
When connecting up a solar system, use a
PT-1000 sensor (S01) as a collector sensor
and a PT-1000 sensor (S02) as the lower
storage tank sensor.
n
All sensors are to be connected to the indoor
module switch cabinet in accordance with the
terminal assignment diagram.
Contact sensor
Contact sensors can be mounted on the pipes, to
measure the heating-circuit temperatures, for
example.
n
The contact sensors are fastened to a pipe
with the accessories provided.
n
Clean the appropriate point. Subsequently 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.
