) D.h.w. heating only, no space heating (summer operation)
2
) D.h.w. heating and, at the same time, normal heating operation (heating season)
3
) No heating load (Off by ECO)
4
) On completion of d.h.w. heating, the heating circuit pump is immediately activated;
this may lead to a temperature rise in the heating circuit

3.8.2 Pump
kick
Periodic pump run is provided to prevent pump seizure during longer off periods (e.g. in
the summer). After the last regular use of the pump, the pump kick is provided for one
minute at 156-hour intervals.
3.9 Interactions with room units
3.9.1 General
Room units can act on the RVP201/211 only if the controller works in one of the two
automatic modes
or
The room temperature acquired by a room unit is adopted by the RVP201/211 at
terminal A6. If the room temperature acquired by the room unit shall not be consid-
ered by the control functions, the room authority must be set to 0 %. In that case, all
the other room unit functions will be maintained
If an inadmissible room unit is connected, the RVP201/211 decides that a fault has
occurred and the room unit will be switched to a passive state, which means that any
actions performed on the room unit have no effect
