OPERATION
Installing the QAA73 room sensor on the boiler can-
cels the functions of the setting potentiometers of
the heating (1) and domestic hot water (2) tempera-
tures on the boiler control panel. All the temperatu-
res, the operating settings and the heating
programmes are set on the QAA 73 (please refer to
the instructions supplies with the sensor).
Note:
- For heating by radiators or by under-floor heating,
refer to section 4.2.3 - page 26.
4.3.1 - Automatic summer/winter switching
Refer to section 3.13 - page 25.
4.3.2 - Room temperature compensation
function
This function corrects the boiler flow temperature
according to the real room temperature measured
by the QAA 73 room sensor.
The QAA 73 can be deactivated or configured diffe-
rently according to the wishes of the customer (refer
to heating engineer setting line 75).
Note:
- The “room temperature compensation” function is
activated by default on the CC1 heating circuit -
standard configuration of the sensor.
- The function is activated if the room sensor is pla-
ced in a room whose temperature is typical of the
accommodation. This room must not be fitted
with temperature control radiators. The room sen-
sor must be fitted away from sources of heat or
cold.
When the room temperature compensation is inac-
tive, the QAA 73 room sensor becomes a remote
control device acting on the heating curve for the
day-night temperature drops.
4.3.3 - Auto-adapt function
This function automatically corrects the heating cur-
ve by measuring the real room temperature.
The auto-adapt function is deactivated in the basic
configuration. It can be activated via line 77 by using
the +/- keys.
When the auto-adapt function is activa-
ted, the room temperature compensa-
tion function must also be activated,
section 4.3.2 - page 29.
