7.3 Heat source connection
The following procedure must be observed when making the
connection:
Connect the well pipes to the heat pump's flow and return.
ATTENTION!
It is essential that the dirt trap included in the accessories pack is
installed in the return (inlet).
ATTENTION!
The well water must comply with the required water quality standards
(see see Cap. 9.4 on pag. 10).
The hydraulic integration diagram must be adhered to.
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)

The temperature sensors to be connected to the heat pump man-
ager must correspond to the sensor characteristic curve illus-
trated in Fig.7.1. The only exception is the outside temperature
sensor included in the scope of supply of the heat pump (see
Fig.7.2)
Fig. 7.1:Sensor characteristic curve NTC-10
Fig. 7.2:Sensor characteristic curve NTC-2 according to
DIN 44574 Outside 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
Sensor lead: Max. length 40 m; min. core cross-section
0.75 mm²; external diameter of the cable 4-8 mm.
