8.2.2 - REMOTE CONTROL
A - FRONT PANEL
• Keys:
1 - Increase temperature set-point.
2 - Decrease temperature set-point.
3 - Air-conditioner operating mode selector.
4 - Ventilation operating mode selector.
• LED lights:
5 - Set-point temperature.
6 - Signalling (option).
7 - Operation in heating mode.
8 - Operation in cooling mode.
9 - "Standby" operating mode.
10 - "Automatic" operating mode (heating or cooling).
11 - "Ventilation only" operating mode.
12 - "Cooling only" operating mode.
13 - "Heating only" operating mode.
14 - "Automatic ventilation" mode.
15 - "Manual ventilation" mode (3 speeds).
B - INSIDE:
• Adjustment of differentials (see details in § 8-3):
- The neutral zone (between heating cut-off and cooling cut-
off) is adjusted in the factory at 1K. P2 enables adjustment
up to 5 K.
- The difference between the triggering of the
thermodynamic heating and the possible make-up heating
is adjusted in the same way by P1.
- P3 is not used.
The adjustment of the potentiometers can only be done by
steps of 1 K. To do this, adjust the potentiometers on marks 1,
2, 3, 4 or 5.
For the intermediate positions, the electronics automatically
select the following whole value.
