7.4 Temperature sensor

The following temperature sensors are already installed or must
be installed additionally:
 Outside temperature sensor (R1) supplied (NTC-2)
Return temperature heating circuit (R2) installed (NTC-10)

Return temperature primary circuit (R24) installed (NTC-

10)
 Flow temperature heating circuit (R9) installed (NTC-10)
Flow temperature primary circuit (R6) installed (NTC-10)

The temperature sensors to be connected to the heat pump
manager must correspond to the sensor characteristic curve il-
lustrated in Fig. 7.2 on page 7. The only exception is the outside
temperature sensor included in the scope of supply of the heat
pump (see Fig. 7.3 on page 7)

7.4.2 Mounting the outside temperature
sensor
The temperature sensor must be mounted in such a way that all
weather conditions are taken into consideration and the meas-
ured value is not falsified.
 Mount on the external wall on the north or north-west side
where possible
 Do not install in a "sheltered position" (e.g. in a wall niche or
under a balcony)
Not in the vicinity of windows, doors, exhaust air vents, ex-

ternal lighting or heat pumps
 Not to be exposed to direct sunlight at any time of year

7.4.3 Installing the strap-on sensor

It is only necessary to mount the strap-on sensors if they are in-
cluded in the scope of supply of the heat pump but have not yet
been installed.
The strap-on sensors can be fitted as pipe-mounted sensors or
installed in the immersion sleeve of the compact manifold.
Mounting as a pipe-mounted sensor
Remove paint, rust and scale from heating pipe.

Coat the cleaned surface with heat transfer compound (ap-

ply sparingly).
 Attach the sensor with a hose clip (tighten firmly, as loose
sensors can cause malfunctions) and thermally insulate.
