7.5 Temperature sensor

The following temperature sensors are already installed or must
be installed additionally:
External 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)
 Return temperature primary circuit (R6) installed (NTC-10)
 Domestic hot water temperature (R3) 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 pag. 10. The only exception is the exter-
nal temperature sensor included in the scope of supply of the
heat pump (see Fig.7.3 on pag. 10)

7.5.2 Mounting the external 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,
external lighting or heat pumps
Not to be exposed to direct sunlight at any time of year

7.6 Electrical connection

7.6.1 General
All electrical connection work must be carried out by a trained
electrician or a specialist for the specified tasks in accordance
with the
installation and operating instructions,

country-specific installation regulations (e.g. VDE 0100),

technical connection conditions of the energy suppliers

and supply grid operators (e.g. TAB) and
local conditions.

To ensure that the frost protection function of the heat pump
works properly, the heat pump manager must remain con-
55 60
nected to the power supply and the flow must be maintained
through the heat pump at all times.
The switching contacts of the output relay are interference-
suppressed. Therefore, depending on the internal resistance of
the measuring instrument, a voltage can also be measured
when the contacts are open. However, this will be much lower
than the line voltage.
Extra-low voltage is connected to controller terminals N1-J1 to
N1-J11; N1-J19; N1-J20; N1-J23; N1-J24 and the terminal
strips X3. If, due to a wiring error, the line voltage is mistakenly
connected to these terminals, the heat pump manager will be
destroyed.
