3. Appliance description
The second generation heat pump manager, also referred to as
WPM3, is responsible for the processes that control and regulate
all our heat pumps.
Connected heat pumps are controlled via the digital BUS connec-
tion that handles the bi-directional data exchange
Cascade control
Up to 6output 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
- 3 dual compressor heat pumps with identical compressors
- From the third connected heat pump upwards, an MSM must
be used to control the buffer charging pumps
Function overview
- The 4-wire data BUS enables rapid installation and system
extension using the MSM mixer module
- Control of a second heat source for DHW and heating
- 9 temperature inputs as set/actual value display
- Demand-dependent control of 7 different circulation pumps
- Input of the system and heat pump frost protection limits
- At least 10 h power reserve for the clock
- Automatic pump kick control
- Reset option
- Stored fault list with precise fault code indication on the dis-
play, including date and time
- Fast and precise fault diagnosis with system analysis, incl.
temperature scanning of heat pump and peripherals without
additional equipment.
- Default settings for time switch programs for all heating and
DHW circuits
- Solar differential controller
3.1 Heat pump types
Note
Heat pump type 5/5* cannot be connected directly to the heat pump manager.
 Use an indoor unit with integral WPM 3 heat pump manager for these heat pumps.
The description of individual functions varies between the different heat pump types. The types of heat pump are therefore identified
in this document as HP type 1 to 5 and 1* to 5*.
