Working
The room temperature control allows you to prevent the air
curtain from overheating the room.
If the temperature in the room exceeds a certain value (the set
point), the discharge air temperature will be reduced to the
half temperature.
You set the set point using function no. 5 at the manager's
level (see section 4.2.3).
The half temperature is the average of the set point and the
discharge air temperature, as pre-set by the user (see section
3.2 'Selecting the air curtain
Options
Function no. 51 at the installer's level (see section 4.3.3) allows
you to let the room temperature control work based on
either the temperature of the air taken in or the ambient tem-
perature near the control panel.
