• 

RAT in normal operation, or

• 

RCT (R/C sensor) in I-FEEL mode.

2)  

The resolution of RT is 1

o

c.

• 

RT is activating COMP/WVL if (RT > SPT), and

• 

RT is stopping COMP/WVL if (RT =< SPT).

3) 

Indoor Coil Temp is detected by ICT (RT2).

4) 

Outdoor Coil Temp is detected by OCT (RT3).

5)
