Buderus heat pump manager HMC 20.
For all Logatherm heat pumps WPL ..A Device description: Necessary. Accessories for the control of externally installed
heat pumps WPL..A with full graphic display and menu navigation, running time optimised and heat demand dependent
compressor control, all operating modes are individually programmable, automatic heating limit function, legionella protection.
All operating modes can be programmed individually, automatic heating limit function, legionella protection program, screed heating program, pump optimisation program, control of
several heat generators, control of a mixing circuit (charging/discharging/cooling circuit), data logger function,
fault diagnosis program with fault memory, short program for customer service, commissioning assistant,
venting program, quick charging function for hot water preparation, automatic summer/winter time function, . Summer/winter time function,
holiday time function, multilingual, expandable. For wall mounting in the installation room. Colour of the housing white.
The heat pump manager is installed inside the building.
- Frost-free installation required
- Wall mounting
- 2 heating circuits can be controlled
- One unmixed and one mixed heating circuit
- A further 2 mixed heating circuits can be controlled via the additional HMC 20 Z board.
- Consumers up to a total of 1450 W can be connected to the outputs.
- External high-efficiency pumps from heating circuits must be connected to the WPM via an on-site relay
due to the high starting current.
Further advantages of the heat pump manager HMC 20:
- Menu navigation with different levels - Plain text display - Data logger recording of all
temperatures, all digital outputs and inputs and setpoint temperatures over a period
of 48 hours and a resolution of 1 minute.
- Data exportable to Excel
- Screed heating program
- Self-coding of the heat pumps. The WPM recognises the type of heat pump connected.
- All parameters for this type are automatically set.
- Control of a circulation pump with separate output, setting of switching times and cycle times
- Separate input for external return sensor
- Control of 2 external heat generators - Collective error message output as an alternative to the 2nd heat generator
- Priorities heating/hot water can be set
- Quick charge for hot water (activation of all heat pumps).
- Parallel connection of several heat pumps, up to 4 heat pumps can be combined
- Pump optimisation programme (running times of the heating circulators)
- Timers for all control loops with more convenient settings
- Holiday time function (holiday clock) - Commissioning wizard
- Query of important parameters for heat pump function
- Storage of commissioning data on the control unit in order to be able to restore them
- Storage of the IBN parameters on a stick
- Guidance through the most important settings
- Setting the setting by selecting the number Hydraulic diagram
- Special operating level for the customer, in which he can carry out the most important settings for the heating system.
- Hygiene circuit for hot water (thermal disinfection)
