Green mode is activated by pressing this button. It is accessible only
when the cover of the controller is open
Deactivation:
By pressing again the green button
During intermediate seasons, the demand for heat can possibly be covered by the solar
collectors and the wood-fired boiler. The conventional heat sources (oil / gas / electrical
immersion heaters / heat pump) will be locked.
Comfort losses – should they occur – will be accepted!
With operating parameter 801 (effect of the green button), it is possible to decide
whether the heat generation lock shall act when there is a demand for heat from d.h.w.,
the heating circuit, or from both. It is thus possible to define with which consumers
comfort losses – should they occur – will be accepted.
LED green mode is lit. The display does not change.
The green button has no impact on the frost protection function.
