3. Appliance description
The WPM heat pump manager is the main controller of the ex-
tendible WPM system. The device assists the control of one di-
rect heating circuit and two heating circuits with mixer. Two heat
pumps can be operated in a cascade. The device provides a 230V
fault contact for external pick-up of system faults. High efficiency
circulation pumps can be connected directly via relay outputs or
PWM outputs. The PCB of the WPM is located in a wall mounting
enclosure that can also accommodate other components such as
the relay for the top-hat rail. The entire system is operated via the
integral programming unit with Touch-Wheel. An internet inter-
face and Smart Home interfaces are available as options.
Cascade control
Up to 6heat pump stages can be controlled for heat generation.
The maximum permitted configuration for cascade control is sub-
ject to the type of heat pump you are using.
- 6 single compressor heat pumps
- From the third connected heat pump upwards, a WPE heat
pump extension must be used
Function overview
- The 4-wire data BUS enables rapid installation and system
extension using the WPE heat pump extension
- Control of a second heat source for DHW and heating
- Demand-dependent control of different circulation pumps
- Input of the system and heat pump frost limits
- At least 10h power reserve for the clock
- Automatic pump kick control
- Reset option
- Stored notification list with precise fault code indication on
the display, including date, time and heat pump index
- Fast and precise fault diagnosis with a system analyser in-
cluding temperature scanning of heat pumps and peripherals
without additional equipment
- Default settings for time switch programs for all heating and
DHW circuits

3.1 Accessories
The following accessories can be installed for additional control
of the heat pump.
3.1.1 FE7 remote control
PIC00000609
The rotary selectors on the FE7 remote control can be used to
make the following settings:
- Changing the set room temperature for heating circuit 1 by
±5°C
- Changing the operating mode
Note that the set room temperature can be changed only in ad-
justable operating modes.
Symbol Operating mode
PROGRAMMED OPERATION
ECO MODE
COMFORT MODE
Note
The remote control is only effective in the heat pump
manager's PROGRAMMED OPERATION mode.
You can set the temperature for heating times in PRO-
GRAMMED OPERATION mode on the remote control.
3.1.2 FET remote control
PIC00006087
The FET digital remote control enables one heating zone to be
controlled. The remote control measures the relative humidity
and room temperature.
