Heating operation
1) Operation is performed at the MAX revolutions shown in the left tables for 3 minutes after com-
pressor operation starts and for 1 minute after defrosting operation ends.
2) Following 1) above, operation is performed at the outdoor unit fan revolutions shown in the left
tables according to the outdoor heatexchanger sensor (TE sensor) temperature.

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).
