Zone E:
Zone A: The fan revolutions are decreased by 100 rpm every 20 seconds
(to the MIN revolutions).
When Zone A operation continues for 5 minutes, the compressor
is stopped and then restarted.
Zone B: The fan revolutions are decreased by 100 rpm every 20 seconds
(to the MIN revolutions).
Zone C: The fan revolutions are decreased by 50 rpm every 20 seconds
(to the MIN revolutions).
Zone D: The fan revolutions are maintained at the current revolutions.
Zone E: The fan revolutions are increased by 50 rpm every 20 seconds
(to the MAX revolutions).
