Functions and ControlDomestic air conditioner7.1.3 Dehumidifying mode.* temperature control range: 60.8---86 F* temperature difference: 30.2/33.8°FControl feature: send the dehumidifying signal to the outdoor system.When Tr>Ts+35.6°F , the compressor will be turned on, the indoor fan will operate at the set speed.When Tr is between the Ts and Ts+35.6°F , the outdoor system will operate at the high dehumidifyingfrequency for 10 minutes and then at the low dehumidifying mode for six minutes. The indoor fan willoperate at low speed.When Tr< Ts, the outsystem will be stopped, the indoor fan will be stopped for 3 minutes and then turned tothe low speed option.All the frequency converses have a 30.2/33.8°F difference.* Wind speed control: Automatic:When Tr Ts+41°F , high speed.When Ts+37.4°F Tr< Ts+41°F , medium speed.When Ts+35.6°F Tr< Ts+37.4°F, low speed.When TrIf the outdoor fan stopped, the indoor fan will be paused for 3 minutes.If the outdoor fan stopped for more than 3 minutes and the outdoor system still operates, the system will bechanged into light speed mode.When the airflow speed has no delay from the high to low switching, the speed should be delayed for 3minutes (remain at high speed for 3 minutes.) before the next switch.Manual: When the sensor is off or Tr< Ts+37.4°F, the manual operation can not be made. (obligatory automaticoperation.)*Airgate location control: the location for the airgate can be set according to your needs.*Defrosting function: preventing the frosting on the indoor heat exchanger (when cooling or dehumidifying).When the compressor works continuously for 1/6 minutes (adaptable in EEPROM) and the temperature ofthe indoor coils has been below zero centigrade for 10 seconds, the compressor will be stopped and themalfunction will be recorded in the malfunction list. The indoor system will continue to run. When thetemperature of the indoor coil is raised to 44.6°F, the compressor will be restarted again (the requirement of 3minutes’ delay should be satisfied.)* Coil protection (synchronic overheating protection) are installed for the four directions latch malfunctionswhen dehumidifying.* Timing system on/off function.* Dormant control functio n.7.1.4 Heating operation mode.* temperature control range: 60.8---86 F* temperature difference: 30.2/33.8°F* control feature: the temperature compensation is automatically added and the system will send the heatingsignals to the outdoor system.If Tr Ts, the outdoor compressor is turned on, the indoor fan will be at the cold air proof mode.If Tr>Ts+35.6°F, the outdoor system is turned off, the indoor fan will be at the heat residue sending mode.If Tr<<
