Heat generation is released by the heat demand signal from a consumer:
• LPB capable controllers signal the RVA47.320 their current heat demand directly
via LPB.
• Controllers not suited for use with the LPB can deliver their heat demand signal via
input H1.
When there is no heat demand signal from the consumers (no LPB capable controllers
connected and no possibility to use input H1), the controller itself can generate a
weather-compensated flow temperature (adjustment of heating curve with a valid
value).
