7.6 Heat pump manager
7.6 Electrical connection heat pump manager
7.6.1 Connection work WPM 2006 plus/WPM 2007 plus
1) The four-core supply cable for the output section of the
heat pump is fed from the heat pump meter via the utility
company's contactor (if required) into the heat pump (3L/
PE~400V,50Hz).
The system must be protected according to the power con-
sumption data on the type plate using a 3-pole miniature cir-
cuit breaker with C characteristic and common tripping for all
3 paths
Cable cross-section according to DIN VDE 0100
2) The three-core supply cable for the heat pump manager
(heating controller N1) is fed into the heat pump (device with
integrated controller) or to the future mounting location of the
wall-mounted heat pump manager (WPM).
The (L/N/PE~230 V, 50 Hz) supply cable for the heat pump
manager must have a constant voltage. For this reason, it
should be tapped upstream from the utility blocking contac-
tor or be connected to the household current, as important
protection functions may otherwise be lost during a utility
block.
3) The utility blocking contactor (K22) with 3 main contacts
(1/3/5 // 2/4/6) and an auxiliary contact (NO contact 13/14)
should be dimensioned according to the heat pump output
and must be supplied by the customer.
The NO contact of the utility blocking contactor (13/14) is
looped from terminal strip X2 to plug terminal J5/ID3. CAU-
TION! Extra-low voltage!
4) The contactor (K20) for the immersion heater (E10) of
mono energy systems (HG2) should be dimensioned ac-
cording to the radiator output and must be supplied by the
customer. It is controlled (230 V AC) by the heat pump
manager via the terminals X1/N and J13/NO 4.
5) The contactor (K21) for the flange heater (E9) in the do-
mestic hot water cylinder should be dimensioned according
to the radiator output and must be supplied by the cus-
tomer. It is controlled (230 V AC) by the heat pump manager
via the terminals X1/N and J16/NO 10.
6) The contactors mentioned above in points 3, 4 and 5 are in-
stalled in the electrical distribution system. The five-core
mains cables (3L/N/PE 400 V ~50 Hz) for the radiators
should be rated and protected according to DIN VDE 0100.
7) The heat circulating pump (M13) is connected to terminals
X1/N and J13/NO 5.
8) The domestic hot water circulating pump (M18) is con-
nected to the terminals X1/N and J13/NO 6.
9) The brine or well pump is connected to the terminals X1/N
and J12/NO 3.
With air-to-water heat pumps,a heat circulating pump
must not be connected on this output!
10) The return sensor (R2) is either directly integrated in brine-
to-water and water-to-water heat pumps or is included in the
scope of supply as a separate component.
The return sensor is integrated in air-to-water heat pumps
for indoor installation and is connected to the heat pump
manager via two single-core wires in the control cable. Both
single-core wires are connected to the terminals X3 (ground)
and J2/B2.
With air-to-water heat pumps for outdoor installation, the re-
turn sensor must be mounted on the shared heating and do-
mestic hot water return (e.g. immersion sleeve in the com-
pact manifold).
The connection on the heat pump manager also takes place
on the terminals: X3 (ground) and J2/B2.
11) The external sensor (R1) is connected to the terminals X3
(ground) and J2/B1.
12) The domestic hot water sensor (R3) is installed in the do-
mestic hot water cylinder and is connected to the terminals
X3 (ground) and J2/B3.
13) The heat pump and the heat pump manager are connected
to each other (round plug) via coded control cables which
must be ordered separately in the case of heat pumps in-
stalled outdoors. In the case of heat pumps with hot gas de-
frosting only, connect the single-core wire (No.8) to the ter-
minal J4-Y1.
NOTE
When using three-phase current pumps, a power contactor can be acti-
vated with the 230V output signal of the heat pump manager.
Sensor cables can be extended with 2 x 0.75mm cables up to 30 m.
