Electrical connection

General

• WARNING Electrocution
  Carry out all electrical connection and installation work in accordance with national and regional regulations.

• WARNING Electrocution
  I solate the heat pump from the power supply when carrying out any work.

• WARNING Electrocution
  The connection to the power supply must be in the form of a permanent connection. Ensure the appliance can be separated from the power supply by an isolator that dis-connects all poles with at least 3 mm contact separation. This requirement can be met by using contactors, circuit breakers, fuses/MCBs, etc.

• WARNING Electrocution
  Only components that operate with safety extra low voltage (SELV) and that ensure secure separation from the mains voltage supply may be connected to the low voltage terminals of the appliance.
  Connecting other components can make parts of the ap-pliance and connected components live.

• Only use components which have been approved by us.

Material losses

• When connecting up, note the maximum load capacity of the relay outputs (see chapter “Specification / Data table”).

Note
The specified voltage must match the mains voltage. Ob-serve the type plate.

Note
In conjunction with the WPM heat pump manager, use the HSM mixer servomotor.

• When connecting the power, observe the relevant electrical connection diagram for the heat pump.
• Protect the device on site with a 6 A circuit breaker.

The supply voltage at terminal L and the phase L’ – switched by the power supply utility – must be routed via the same residual current device, as they share a neutral conductor in the WPM.

• Ensure that L and L’ are in phase.
• Disconnect all heating system poles from the mains power supply before installation.

No fuses/MCBs for connected consumers are provided in the WPM or in the wall mounting enclosure. A fuse for connected consumers may be connected in series via terminal L* or pumps L (see also heat pump connection diagram).

Appliance connection
The cable entries in the wall mounting enclosure are suitable for rigid and flexible cables with an outside diameter of 6-12 mm.

• Lay flexible cables in conduits or cable ducts.

Mains and low voltage power circuits are routed separately in the wall mounting enclosure.

Material losses
Bus cables, power cables and sensor leads must be in-stalled separately .

1. Front cable entry for mains voltage
2. Rear cable entry for low voltage

• Route the low voltage leads from below into the rear cable entry on the device.
• Route the mains power cable from below into the front cable entry on the device.
• When connecting the mains voltage, ensure the earth con-ductor is correctly connected.
• Secure all electrical cables directly below the wall mounting enclosure with the red wedges supplied.

Note
The red wedges are for securing the cables.

• Do not use the red wedges for strain relief.

Material losses

• Tighten all the screws on the terminals. Screws on unconnected terminals must also be tightened.

Terminal assignment

1. Retainer for connecting cable from programming unit
2. Micro-SD card slot
3. CAN bus for programming unit

• Lay the connecting cable from the programming unit over the retainer.

Note
For every appliance fault, output X2.10 issues a 230 V signal.
In the case of temporary faults, the output switches the signal through for a specific time.
In the case of faults that result in a permanent appliance shutdown, the output switches through permanently.

• You can define the characteristics of the output via parameter “COMMISSIONING / I/O CONFIGURATION / OUTPUT X 2.10”.

Sensor installation

Note

• Only use PT1000 sensors.
• Connect all of the required sensors before commissioning the appliance.

AF PT outside temperature sensor
The temperature sensors have a significant influence on the func-tion of your heating system. Therefore ensure sensors are correctly positioned and well insulated.

Commissioning

Only qualified contractors may carry out any adjustments to the heat pump manager (see list in the chapter “Settings / Setting pa-rameters” in the heat pump manager commissioning instructions), commission the device and instruct the system user in its use.
Commissioning must be carried out in accordance with these in-stallation instructions and the operating and installation instruc-tions of all components belonging to the heat pump system.

Note
Our customer support can assist with commissioning, which is a chargeable service.

Bus initialisation
Connecting the bus cable not only establishes the electrical con-nection for system communication. As part of commissioning, connecting the bus cable will also assign the appliance-specific address required for switching the heat pump.

General information

Note
The control panel for each heat pump provides space for the connection of two 3-core BUS cables, i.e. the BUS cable between the heat pumps is wired in parallel.

Note
In a cascade, heat pumps designed to heat DHW must always be initialised first. The remaining heat pumps can then be initialised in any order.

Note
All necessary sensors must be connected before the volt-age is connected to the WPM. Any sensors connected later will not be recognised by the WPM.
Example: No DHW parameters, programs or tempera-tures are displayed if the DHW cylinder sensor was not connected at the time of commissioning. No values can be programmed for these parameters.

Note
If incorrectly initialised, all IWS (internal heat pump controllers) must be reset and reinitialised (see chapter “Reset options / Reinitialising the IWS”).

Note
The entire heat pump system will be shut down if the BUS cable between the WPM and the heat pump is in-terrupted.

Note
The connection between heat pump manager and heat pump is carried out via CAN bus. The connection can have a line or star topology.

Sequence when activating the heat pumps for bus initialisation
Requirement: The appliances (heat pump, heat pump manager (WPM) and, where applicable, heat pump extension (WPE)) are connected to each other via the bus.
For bus initialisation, it is essential that you comply with the fol-lowing sequence:

• Connect the WPM to the mains voltage.
• Connect the WPE (if installed) to the mains voltage.
• Connect the internal heat pump controller (IWS) to the mains voltage.
• Leave the mains voltage to the compressor and emergency/booster heater switched off, so that the heat pump does not start up uncontrolled during initialisation.

In the DIAGNOSIS / SYSTEM menu, all connected BUS subscrib-ers and their respective software versions are shown under BUS SUBSCRIBER.
After completing initialisation of the heat pump, use the DIAG-NOSIS / SYSTEM menu under HEAT PUMP TYPES to check that all connected heat pumps are being displayed.

System configuration through parameter settings

If the system is operating incorrectly, you should first check the parameter settings (see chapter “Settings / Parameter summary” in the commissioning instructions for the heat pump manager).

Reset options

Reinitialising the IWS
This reset should be performed if the system was commissioned or initialised incorrectly.
To do so, proceed as follows:

• Switch OFF the mains voltage to the WPM.
• Switch OFF the mains voltage to the WPE (if installed).
• Switch OFF the mains voltage to the heat pump.
• Disconnect the BUS connections.
• Switch ON the mains voltage to the heat pump.
• Hold the reset key until the two outer LEDs are constantly illuminated.
• Release the reset key. The IWS has now been reset and is ready for renewed initialisation.
• Switch the mains voltage to the components back ON.
• Carry out BUS initialisation (see chapter “Commissioning /BUS initialisation”).
• Reset the system-specific parameters for the WPM and WPE.

Heat pump reset
This reset should be performed if a heat pump-specific fault or hardware fault occurs five times in the space of two hours’ runt-ime.

• Activate the HEAT PUMP RESET parameter in the COMMIS-SIONING menu.

The fault is cleared. The heat pump is ready to be returned to use.

Troubleshooting

WARNING Electrocution

• Isolate the heat pump from the power supply when carrying out any work.

Problem

• An info value is not dis-played.

Cause

• The sensor has not been connected correctly.

Remedy

• Isolate the system from the power supply. Con-nect the sensor. Recon-nect the system to the mains voltage.
