7.3 Heat Source Connection

The following procedure must be observed when connecting the
heat source:
Connect the well pipes to the heat pump's flow and return.
ATTENTION!
The well water must comply with the required water quality standards.
The hydraulic plumbing diagram must be adhered to.

7.4 Electrical Connection

The following electrical connections need to be established on
the heat pump.
 Connection of the control line to the control panel of the heat
pump via terminal X1: L/N/PE.
 Connection of the mains cable to the control panel of the
heat pump via terminal X5: L1/L2/L3/PE.
 Connection of the mains cable of the well pump to the con-
trol panel of the heat pump via terminal X5: L11/L21/L31/PE.
 Connection of the well pump (to be provided by the cus-
tomer) to the control panel of the heat pump via terminal X1:
PE and pump contactor K5: 2/4/6.
Ensure that the supply voltage for these terminals cannot be
switched off by the tariff contactor when connecting the mains
cable of the well pump, in order to enable the turn-off delay of the
well pump.
All electrical components required for the operation of the heat
pump are located on the control panel.
For detailed instructions concerning the connection and function-
ing of the heat pump manager (e.g. external wall sensor in-
cluded in the scope of supply), refer to the operating manual sup-
plied with the heat pump manager .
An all-pole disconnecting device with a contact gap of at least
3 mm (e.g. utility blocking contactor or power contactor) as well
as a 3-pole circuit breaker with common tripping for all external
conductors have to be provided by the customer. The required
conductor cross-section is to be selected according to the power
consumption of the heat pump, the technical connection require-
ments of the respective utility company as well as all applicable
regulations. Details on the power consumption of the heat pump
are listed on both the product information sheet and the type
plate. The connection terminals are designed for a max. conduc-
2
tor cross section of 10 mm .
ATTENTION!
Observe the clockwise rotating field when connecting the mains cable (if
rotating field is not clockwise, the heat pump will not work properly and
will be very noisy).

8.1 General




Extra-low voltage is applied to controller terminals N1-J1 to N1-
J11; N1-J24 and terminal strip X2, X3, X4. If, due to a wiring er-
ror, the line voltage is mistakenly connected to these terminals,
the heat pump manager will be destroyed.

connection
During start-up, observe the respective national safety regu-
lations and the applicable VDE safety regulations, particu-
larly VDE 0100, as well as the technical connection require-
ments of the utility companies (EVU) and network operators!
To ensure that the frost protection function of the heat pump
works properly, the heat pump manager must remain con-
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 resist-
ance 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.
