Set point display and adjustment
To display the set point, press two times onto any of the 3 buttons. Set point will be displayed during 5 seconds.
To adjust set point, press on ∆or ∇while the temperature set point is displayed.
Note: If set point adjustment has been locked, symbol will be displayed.
C
Night set back (NSB) :
When thermostat is in night set back mode, NSB symbol is displayed, so set point for cooling and/or heating
are increased as per the setting made in programming mode.
If not locked, night set back can be derogated for a predetermined period by pressing onto any of the 3 buttons.
During period of NSB derogation the symbol will flash. If NSB does not flash, the derogation period is finished
or the Night set back derogation has been locked in programming mode.

On/Off selection :
To set thermostat On/Off, press once onto the button. Control mode will be displayed during 5 seconds.
9Cooling only / OFF
9Heating only / OFF
9Automatic Cooling & Heating / Cooling only / Heating only / OFF
Note: These selections can vary according to the choice made on step #6.
Recycling at end of life
At end of life, please return the thermostat to your Aldes local distributor for recycling. If you need to find the nearest aldes authorized
distributor, please consult www.aldes.ae.
