I fan speed
When the compressor is started, the initial fan speed
is determined according to the current T4 temperature
range. At other times, the T4 temperature range is
invalid. After holding for 30 seconds, adjust the fan speed
according to the T3 temperature: in the fan speed increase
zone, the fan speed increases by one gear, and the
maximum is high fan. In the holding zone, the fan speed
remains unchanged. In the decrease zone, the fan speed
drops by one gear, and the lowest is I gear. When the fan
speed is I gear, if it enters the fan stop zone, the fan will
stop.
