3.2 Temperature sensor

Depending on the hydraulic setup, the following temperature
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 sensor (R35,

R5 and R21)
 Demand sensor (R2.2)
DHW temperature sensor (R3)

 Renewable cylinder temperature sensor (R13)
Flow sensor master function (R9.5)

Return sensor master function (R2.5)


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)
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
HINWEIS
NOTE
The outside temperature sensor R1 is not included in the
scope of supply. The outside temperature sensor for the mas-
ter control is taken from the scope of supply of the heat pump
to be installed.

HINWEIS
NOTE
3.7
For parallel connection with multiple heat pumps in combina-
18.0
tion with a master control, only 1 outside temperature sensor
60
must be mounted for the master control. The master control
transfers the outside temperature to the heat pump manager
0.6
of the heat pumps via the communication connection.

3.2.3 Installing the strap-on sensor

50 55 60
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
