- With no QAA 70 room sensor on the mixer valve
circuit:
• the mixer valve circuit flow temperature is defi-
ned by the slope of the RVA 46 for a 20 °C
room temperature,
• corrections relating to this room temperature
are carried out by the room temperature con-
trol knob of the RVA 46 (item no. 1, fig. 19)
(setting from 8 to 26 °C).
- With a QAA 70 room sensor on the mixer valve
circuit:
• the room temperature control knob of the
RVA 46 (item no. 1, fig. 19) becomes inactive,
• the mixer valve circuit room temperature set-
ting is set on the room sensor (setting value
programmed in line 1 of the room sensor + cor-
rection with the control knob +/- 3 °C).
A circuit equipped with a mixer valve can control a
floor heating system by setting the slope of the
RVA 46 to 8.
