Temperature sensors External sensor
■
The number of sensors required
can vary with the type of
system.
■
In the indoor module (F11),
the collector sensor, the return
sensor (F17) and the sensor
for the liquid line (refrigeration
circuit) are already installed and
connected.
■
Observe the pertinent notes
for the sensor position found
in the hydraulic schematic.
■
The standard model
includes an external sensor,
a submersible sensor (intended
for use as a custom hot-water
sensor), as well as a contact
sensor.
■
When connecting solar panels,
the PT-1000 sensor must be
used to measuring the collector
temperature! (F14) All other
sensors must be NTC-sensors
with a reference resistance of
5 kilo Ohms.
■
All sensors are to be connected
to the indoor-module
switching-cabinet according
to the terminal-assignment
diagram.
The connection of an outdoor
sensor is always required for the
heat pump manager.
■
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.
■
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.
Contact sensor
Contact sensors can be mounted
on the pipes, to measure the
heating-circuit temperatures, for
example.
■
The contact sensor is fastened
to a pipe with the trapezoidal
brackets and retaining strap
provided.
■
Clean the mounting point on
the pipe. 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.
