11.4.3.2 Indoor Fan Control in Heat Mode

Indoor fan speed depends on the indoor coil temperature:

11.4.4 Auto Cool/Heat Mode

When in auto cool heat mode unit will automatically select between cool and heat mode according

to the difference between actual room temperature and user set point temperature (

∆

T).

Unit will switch from cool to heat when compressor is off for 3 minutes, and

∆

T < -3. Unit will

switch from heat to cool when compressor is off for 5 minutes, and

∆

T < -3.

11.4.5 Dry Mode

As long as room temperature is higher then the set point, indoor fan will work in low speed and

compressor will work between 0 and MaxNLOADIF1C Hz.

When the room temperature is lower than the set point, compressor will be switched OFF and

indoor fan will cycle 3 minutes OFF, 1 minute ON.

11.4.6 Indoor Units Operation when Indoor Unit Mode is Different than

Outdoor Unit Mode

●

Open louvers according to user selection.

●

Indoor fan is forced to OFF.

11.4.7 Indoor Unit Dry Contact

Indoor unit Dry contact has two alternative functions that are selected by J9.
