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 secondary circuit (R2) installed
(NTC-10)
Return temperature primary circuit (R24) installed (NTC-
10)
Flow temperature secondary circuit (R9) installed (NTC-10)
Flow temperature primary circuit (R6) installed (NTC-10)
7.4.1 Sensor characteristic curves
The temperature sensors to be connected to the heat pump
manager must correspond to the sensor characteristic curve il-
lustrated in Fig. 7.2. The only exception is the outside tempera-
ture sensor included in the scope of supply of the heat pump
(see Fig. 7.3)
Fig. 7.2:Sensor characteristic curve NTC-10
Fig. 7.3:Sensor characteristic curve NTC-2 according to DIN 44574 Out-
side temperature sensor
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.
On the external wall of a heated room used as living space,
if possible on the north or north-west side of the building
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.
