Example
Nighttime free cooling operation
〈AUTOMATIC HEAT PORGE FUNCTION AT NIGHT〉
The nighttime free cooling is an energy-conserving function
which works at night when the air conditioners is off, reducing
the cooling load in the morning when the air conditioner is
turned on by ventilating rooms which contain office
equipment which raises the room temperature.
• Nighttime free cooling only works during cooling and
when connected to Building Multi or VRV systems.
• Nighttime free cooling is set to “off” in the factory settings;
so request your dealer to turn it on if you intend to use it.

after the air conditioning operation stops for the night. If
the following conditions are satisfied, the operation starts,
and when the indoor temperature reaches the air
conditioning setting, the operation stops.
<Conditions>
1. the indoor temperature is higher than the air conditioning
setting and
2. the outdoor temperature is lower than the indoor
temperature,
If the above conditions are not satisfied, revaluation is made
every 60 minutes.

free cooling operation, though the forced off is input from
the optional controllers for centralized control.
