When pressing the green button, the heat sources operating on nonrenewable forms of
energy (oil / gas / heat pump / electric immersion heaters) will be locked. The demand
for heat received from the heating circuits and / or d.h.w. will no longer be considered.
Any comfort losses with regard to the d.h.w. and / or the heating circuits will be accepted.
The operating line makes it possible to define the demand for heat that shall be ig-
nored:
1 D.h.w.
Demand for heat from d.h.w. will be ignored by the above mentioned heat sources.
The d.h.w. will only be heated by heat delivered by a wood-fired boiler or by solar
collectors.
2 Heating
circuit
Demand for heat from the heating circuit will be ignored by the above mentioned
heat sources. The heating circuits will only be heated by heat delivered by a wood-
fired boiler or by solar collectors.
3
D.h.w. and heating circuit
Demand for heat from d.h.w. and the heating circuits will be ignored by the above
mentioned heat sources. All the heat required by the plant is delivered by a wood-
fired boiler or by solar collectors.
Ignoring the demand for heat from d.h.w. is possible only if the d.h.w. is controlled by
the RVP540 / RVP550. In the case of an external demand for heat, no differentiation is
made between d.h.w. and heating circuit.
