The two d.h.w. sensors are inserted into the same
tank and each one is connected to an LGM.
%HQHILWV
- D.h.w. production with a selector valve,
- available d.h.w. heating power: 100 KW,
- limited heat carriage: only the d.h.w. loop is at a
high temperature,
- it is possible to control a floor heating system di-
rectly via the pump circuit of the RVA 47 due to
the limited heat carriage,
- due to the difference in the position of the second
d.h.w. sensor, one LGM is released before the
other which allows a single LGM to finish the tank
switch. The second one can already ensure heat-
ing.
'UDZEDFNV
- two d.h.w. sensors in the tank.

The d.h.w. request must be communicated with the
button (d.h.w. on) of the RVA 47.
- the d.h.w. temperature setting is set either
. in line 13 of the RVA 47,
. or in line 3 of QAA 70 of the RVA 47.
- the d.h.w. setting potentiometers of the LGMs’
control panel are inactive,
- during a d.h.w. request, the relevant BMUs are in
the d.h.w. operating mode (6 on the control panel
display).
