CONTROL SYSTEM 11.1.3.5 Minimum On and Off Time 3 minutes. 11.1.4 Indoor Fan Control 10 Indoor fan speeds are determined for each model. 5 speeds for cool/dry/fan modes and 5 speeds for heat mode. When user sets the indoor fan speed to a fixed speed (Low/ Medium/ High), unit will operate constantly at set speed. When Auto Fan is selected, indoor unit controller can operate in all speeds. The actual speed is set according to the cool/heat load. 11.1.4.
PAGE 77
CONTROL SYSTEM Notes: When OAT is faulty or disabled OFAN will follow ‘Normal cases’ rules (left column). 1. The table above can be overruled during protections. 2. OFLowFreq = OFLowFreqC in cool mode, and OFLowFreqH in heat mode. 3. OFMedFreq = OFMedFreqC in cool mode, and OFMedFreqH in heat mode. ● The OFAN will be off when the compressor is off. ● An exception for the following rule is when compressor was operating in cool mode before stopped.

CONTROL SYSTEM 11.1.7 EEV (electronic Expansion valve) Control 1. For S/W 37V3 and lower ( For 453031000R Controller) EEV opening is defined as EEV = EEVOL + EEVCV ● EEVOL is the initial EEV opening as a function of the compressor frequency, operation mode, unit model and capacity. ● EEVCV is a correction value for the EEV opening that is based on the compressor temperature. ● During the first 5 minutes of compressor operation EEVCV = 0.

TROUBLESHOOTING 12.1.5 Simple procedures for checking the Main Parts 12.1.5.1 Checking Mains Voltage. Confirm that the Mains voltage is between 198 and 264 VAC. If Mains voltage is out of this range, abnormal operation of the system is expected. If in range check the Power (Circuit) Breaker and look for broken or loosed cable lugs or wiring mistake(s). 12.1.5.2 Checking Power Input. If Indoor unit power LED is unlighted, power down the system and check the fuse of the Indoor unit.
