Installation and Operating Instructions
4. Cool blowing inhibiting control : In order to inhibit cool blowing during heating operation, the fan motor is operated when
temperature of the "indoor pipe thermistor" is above the specified value.
• The fan motor speed is controlled according to the temperature of condition of the "indoor pipe thermistor".
< Compressor OFF -> Compressor ON >
1) When the "indoor pipe thermistor" temperature is increasing
"indoor pipe thermistor" temperature = below 32˚C --> fan motor OFF
"indoor pipe thermistor" temperature = over 32˚C --> fan motor speed "set blower speed"
2) When the "indoor pipe thermistor" temperature is decreasing
"indoor pipe thermistor" temperature = over 30˚C --> fan motor speed "set blower speed"
"indoor pipe thermistor" temperature = below 30˚C --> fan motor speed "Low"
3) But if the compressor is operating, the fan motor is not turned off but is operated weakly even if the "indoor pipe ther-
mistor" temperature decreases.
