• If the fan speed has been changed once, it is not changed
for 1 minute. However when the air volume changes, the
fan speed changes.
• When heating operation has started, select an upward
slope for the fan speed, that is, the high position.
• If the temperature is just on the margin the fan speed does
not change.
• In TC2
≥
140°F[60°C], the fan speed increases by clarify 1
step.

1. In heating operation, the higher temperature of TC2 sensor
and TCJ sensor is compared with temperature of TC1
sensor and then the lower temperature is used to set the
upper limit of the fan tap.
• When B zone has continued for 6 minutes, the opera-
tion shifts to C zone.
• In defrost time, the control point is set to +10.8°F[6°C].
