Notes:
- Application limits: Compressor T_FL/T_RTN = 55 °C, elec. heater T_FL = 75 °C
- Enable electric heater for heating mode (WP090 = ON)
- CongureoutputA1todefrost(WP003=Defrost)

in order to display defrost mode to the BMS.
- Ensure max. compressor starts per hour by BMS

- Connect dew point monitor or jumper to input E1
- Ensure dew point monitoring by BMS if required

Inthissystemconguration,theappliancecancarryoutDHWheat-upautomatically
on demand. DHW heat-up mode has priority over BMS mode.
DHWheat-upmodecanbesuppressedinsystemconguration51byremoving
the SF cylinder sensor, carrying out a parameter reset and resetting the system
conguration.
In this case, disconnect integral 3-way diverter valve for HTG/DHW.
A 3-way diverter valve for
central heating/DHW and a
feed/heating circuit pump
are integrated into the

Important information:
In these schematic diagrams, shut-off valves, air vent valves and safety equipment are not fully represented.
These should be provided for each system individually, in line with the applicable standards and regulations.
