3.2 Temperature sensor

Depending on the heat pump type used, the following temper-
ature sensors are already installed or must be additionally
mounted:
NTC-2 sensor:
Outside temperature sensor (R1)

NTC-10 sensor:
1st, 2nd and 3rd heating circuit temperature sensors (R35,

R5 and R21)
 Demand sensor (R2.2)
Domestic hot water temperature sensor (R3)

Renewable cylinder temperature sensor (R13)


The temperature sensors to be connected to the heat pump
manager must correspond to the sensor characteristic curve il-
lustrated in Fig. 3.3 on page 7. The only exception is the outside
temperature sensor included in the scope of supply of the heat
pump (see Fig. 3.4 on page 7)

3.2.2 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)
Do not install in the vicinity of windows, doors, exhaust air

vents, external lighting or heat pumps
 Not to be exposed to direct sunlight at any time of year

3.2.3 Installing the strap-on sensor

3.1
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
