7.5 Electrical connection
7.5.1 General
All electrical installation 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-
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.
7.5.2 Electrical installation work
1)
The 4-core electrical supply cable for the output section of
the heat pump is fed from the heat pump meter via the util-
ity company blocking contactor (if required) into the heat
pump.
The mains cable is connected at the heat pump switch box
using terminals X1: L1/L2/L3/PE
An all-pole disconnecting device with a contact gap of at
least 3 mm (e.g. utility company blocking contactor or
power contactor) and an all-pole circuit breaker with com-
mon tripping for all external conductors must be installed
in the power supply for the heat pump (tripping current and
characteristic in compliance with the device information).
2)
The three-core supply cable for the heat pump manager
(heating controller N1) is fed into the heat pump.
Connection of the control cable to pin X1.1 "230 V-IN"
(white): L/PE/N.
Details on the power consumption of the heat pump are
listed on both the product information sheet and the type
plate.
The supply cable (L/N/PE~230 V, 50 Hz) for the heat pump
manager must have a continuous voltage. For this reason,
it should be tapped upstream from the utility company
blocking contactor or be connected to the household cur-
rent, because otherwise important protection functions
could be lost during a utility block.
3)
The utility company blocking contactor (K22) with 3 main
contacts (1/3/5 // 2/4/6) and an auxiliary contact (NO
contact e.g. 13/14) should be dimensioned according to
the heat pump output and must be supplied on-site. The
NO contact of the
utility company blocking contactor (13/14) is connected to
pin (1) (=DI1) of function block 0 (grey). CAUTION! Extra-
low voltage!
4)
The contactor (K20) for the immersion heater (E10) of
mono energy systems (HG 2) should be dimensioned ac-
cording to the radiator output and must be provided on-
site. The control (230 V AC) is performed from the heat
pump manager, with the function applied via pin (7) (=NO3)
of function block 0 (grey).
EN-12
5)
The contactor (K21) for the flange heater (E9) in the do-
mestic hot water cylinder should be dimensioned accord-
ing to the radiator output and must be provided on-site.
The control (230 V AC) is performed from the heat pump
manager via pin (7) of the defined function block.
6)
The contactors mentioned above in points 3, 4 and 5 are
installed in the electrical distribution system. The mains ca-
bles for the radiators should be dimensioned and pro-
tected according to DIN VDE 0100.
7)
The heat circulating pump (M13) is connected to pin (5)
(230V) and (8) (control signal) of function block 0 (grey).
8)
The domestic hot water circulating pump (M18) is con-
nected to pin (5) of the defined function block.
9)
The external sensor (R1) is connected to pin (3) (=U1) of
function block 0 (grey).
10) The domestic hot water sensor (R3) is installed in the do-
mestic hot water cylinder and is connected to pin (3) of the
defined function block
NOTE
If three-phase pumps are implemented, a power contactor
can be controlled via the 230 V output signal of the heat pump
manager.
Sensor cables can be extended up to 40 m with 2 x 0.75 mm
cables.
NOTE
Further information on the wiring of the heat pump manager
is available in the electrical documentation.
