TECHNICAL SPECIFICATIONS
4.1 - Control panel
THI Without room sensor or outside sensor
The heating (2) and hot water (3) temperatures set-
ting are manually set on the boiler control panel.
- The FUNCTION key (1) gives access to 2 opera-
ting modes:
• Auto mode operation (4): no access
• Winter mode operation: LED (5) on
• Summer mode operation: LED (5) off
THI Without room sensor and with outside sensor
Possibility of correcting the heating temperature (2)
computed automatically using the outside tempera-
ture and manual setting of the hot water temperatu-
re (3) on the boiler control panel. (The room
temperature setting can be changed by + or - 3°C
maximum according to the setting).
- The FUNCTION key (1) gives access to 3 opera-
ting modes:
• Auto mode function:
auto winter = Leds (4) and (5) on
auto summer = Led (4) on + Led (5) off
• Winter mode operation: LED (5) on
• Summer mode operation: LEDs (4) and (5) off
THI With room sensor and outside sensor
Fitting the QAA73 room sensor cancels the func-
tions of the heating temperature setting (2) and hot
water setting (3) on the boiler control panel. All the
temperatures required, together with the heating
programmes, are set on the QAA 73 (refer to the
sensor instructions).

1) The "Function" key gives access to 3 operating
modes by simply pressing the key:
auto mode: LED (4) on
winter mode: LED (5) on
summer mode: LED (4) and (5) off
2) Regulation of the heating temperature (setting
read on the display (13))
*
3) Regulation of the DHW temperature (setting
read on the display (13))
*
6) Maintenance key: reserved for servicemen or
maitenance (see overleaf)
7) "Info" key gives access to 5 types of information
on the display (13) by simply pressing the key:
Boiler outlet temperature: LED (9) on
Sensor temperature: LED (9) flashing
Boiler water pressure: LED (8) on
Operating phase: LEDs (8/9) off
Diagnostics: LEDs (8/9) off/
Display (13) flashing
10) Boiler reset button (After each reset, wait for
about 30 seconds before the restart = reset)
11) Alarm: Red LED on
12) Flame indicator: Green LED on
13) Digital display: Alternatively displays the setting
selected by the "Info" key and the current default
code
14) ON/OFF switch (depending on the models) **
*
The function of the heating temperature (2) and DHW temperature (3)
potentiometers differs according the 3 examples below.
**
The On/Off switch (after initial lighting) should be maintained in the "ON"
position in order to preserve all the automatic functions of the boiler (an-
ti-freeze, anti-legionella functions, etc).
