Part 4 Functions and Control
4.7 Outdoor Fan Control
1.
Fan ON control to cool down the electrical box
The outdoor fan is turned ON when the electrical box temperature is high while the
compressor is OFF.
2.
Fan OFF delay when stopped
The outdoor fan is turned OFF 60 - 80 seconds after the compressor stops.
3.
Fan speed control for pressure difference upkeep
The rotation speed of the outdoor fan is controlled for keeping the pressure difference during
cooling operation with low outdoor temperature.
When the pressure difference is low, the rotation speed of the outdoor fan is reduced.
When the pressure difference is high, the rotation speed of the outdoor fan is controlled
as well as normal operation.
4.
Fan speed control during forced cooling operation
The outdoor fan is controlled as well as normal operation during forced cooling operation.
5.
Fan speed control for POWERFUL operation
The rotation speed of the outdoor fan is increased during POWERFUL operation.
6.
Fan speed control during indoor/outdoor unit quiet operation
The rotation speed of the outdoor fan is reduced by the command of the indoor/outdoor unit
quiet operation.
7.
Fan ON/OFF control when operation (cooling, dry) starts/stops
The outdoor fan is turned ON when the operation starts. The outdoor fan is turned OFF
when the operation stops.
4.8 Liquid Compression Protection Function
Outline
In order to increase the dependability of the compressor, the compressor is stopped according
to the outdoor temperature.
Details
Operation stops depending on the outdoor temperature.
The compressor turns off under the conditions that the system is in cooling operation and
outdoor temperature is below 0°C (for 50/65/80 class) or below –12°C (for 90 class).
