• Heating energy can be drawn off either by space heating or the DHW storage tank.
This can be selected separately for each heating circuit (operating page "Heating
circuit 1...")
• If the collector is cold, the energy can be emitted to the environment via the
collector's surfaces

The electric immersion heater is only used if the boiler delivers a fault status message
or if it has been shut down via boiler lock. This means that in normal situations the
DHW is heated by the boiler.
Summer
The electric immersion heater is used as soon as all connected heating circuits have
switched to summer operation. The DHW is again heated by the boiler as soon as at
least one of the heating circuits has switched back to heating mode. But the electric
immersion heater is also used if the boiler delivers a fault status message or has been
shut down via boiler lock.
Always
DHW is heated with the electric immersion heater throughout the year. This means that
with this application, the boiler is never required for DHW heating.
24h/day
The electric immersion heater is always released, independent of time programs.
