2.5,8 Sensor installation
The temperature sensors have a decisive
influence on the function of your heating
system. Therefore ensure the correct seating
and adequate insulation of sensors.
Outside temperature sensor AFS 2 (included in
the pack supplied)
Install the outside temperature sensor on a
north or north-eastern wall.
Minimum distances:
2.5 m above the ground
1 m away from windows
and doors. The outside
temperature sensor should
be freely exposed to the
elements, but should not be
installed above windows,
doors or air ducts and
should not be subject to
direct sunlight.
Installation:
- Remove the cover
- Tighten the lower part with screw supplied,
insert and connect the sensor lead
- Replace the cover and let it clearly click into
place
PT 1000 immersion sensor (included in the
pack supplied; only for SOL versions)
Insert the immersion
sensor into the connector
sensor well (see diagram)
Diameter: 6 mm
Length: 1.5 m
The immersion sensor with the
longer silicone lead is the collector
sensor (PT 1000).
The correct connection of the collector sensor
(silicone lead) is crucial to the correct function
of a solar heating system. The sensor on solar
collectors is installed on the last collector,
viewed in the flow direction of the process
medium. For this, install and seal-in the
collector sensor well on the collector. Coat the
collector sensor with heat conducting paste
and insert it into the sensor well tube until it
bottoms out. Provide thermal insulation for
the collector sensor well and the roof outlet,
which must be closed without gap and must
be UV resistant.
Contact sensor AVF 6 (see accessories) This
sensor is required
if a mixer circuit is
installed. Installation
information:
Thoroughly clean
the pipe. Apply heat
transfer paste A, and
secure the sensor
with a cable tie.
