Enabling electric heater for central heating

If the heat pump alone cannot achieve
the selected set room temperature, an
(on-site) instantaneous heating water
heater can be started automatically to
boost central heating.
The constant use of an instantaneous
heating water heater results in higher
power consumption, which therefore
requires it to be enabled.
