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 3.2.3).
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 strength').
Options
Function no. 51 at the installer's level (see section 3.3.3) 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.
This is also the temperature that is shown as the room tem-
perature in the display. Function no. 69 at the installer's level
allows you to disable its display.
The display shows as standard the target discharge air temper-
ature. The -symbol appears in the display if the discharge air
temperature differs from the pre-set temperature. You can
disable this using function no. 74 at the installer's level.
