- Circulating pump Q1 operates as a heating
pump.
- D.h.w. can be ensured:
• either with a d.h.w. pump using the RVA 47,
• either with a selector valve of one of or of the
BMU(s) of the THR 10-100.
- The heating and d.h.w. setting potentiometers of
the boiler’s BMUs are inactive.
- The Summer/Winter potentiometers of the boiler
remain active and must remain on the Winter po-
sition.

- D.h.w. temperature setting:
• See paragraphs 2 -, 3 - section V - BASIC
SETTING OF THE THR 10-100.
• The setting of the d.h.w. temperature setting in
line 13 of the RVA 46s or line 3 of the QAA 70s
of the RVA 46s can be modified but this has no
consequence.
- Heating circuit temperature setting of the RVA re-
gulators (RVA 47 and RVA 46):

. the heating circuit flow temperature is defi-
ned by the RVA’s slope for a 20 °C room
temperature setting.
. Corrections to this room temperature are
carried out by the RVA’s room temperature
control knob (setting from 8 to 26 °C).

. The RVA’s room temperature control knob
becomes inactive.
. The heating circuit’s room temperature set-
ting is set on the room sensor (setting value
programmed in the room sensor line 1 + cor-
rection with the control knob +/- 3 °C).
-Boilers’ setpoint temperature:
• The boilers’ setpoint temperature is the highest
temperature setting of all the zone circuits.

The circulating pump of the heating circuit operates
as soon as the RVA receives a request and the
outdoor temperature is lower than the Summer/Win-
ter switching setting value.
The circulating pump of the heating circuit stops
operating when there is no heating request (e.g.:
RVA on standby – RVA in auto + QAA 70 on stand-
by – RVA in auto + QAA 70 in auto + room tempera-
ture setting reached).
Since the domestic hot water priority is a shifting
priority, during a Domestic Hot Water request:
- When the actual Domestic Hot Water is very dif-
ferent from the D.H.W. temperature setting:
• Pump Q3 operates,
• Pump Q1 of the heating circuit of regulator
RVA 47 stops operating,
• The Q2 pumps of the RVA 46 pump circuits
stop operating,
• The valves of the RVA 46 mixer valve circuits
close (the pumps continue to operate).
- When the actual Domestic Hot Water temperatu-
re nears the D.H.W. temperature setting:
• Pump Q3 operates,
• Pump Q1 of the RVA 47 regulator heating cir-
cuit operates intermittently,
• The Q2 pumps of the RVA 46 pump circuits
operate intermittently,
• The valves of the RVA 46 mixer valve circuits
open (the pumps continue to operate).
- The pumps of the THR 10-100 operate as soon
as there is a zone request (heating or domestic
hot water).
- The pumps of the THR 10-100 stop operating as
soon as there is no more zone request (heating or
domestic hot water).
