2.Automatic Control for Heating and Cooling

Automatic Heating/Cooling Control

(1)When operation starts, heating or cooling is selected according to the set temperature and the room temperature.

Room temperature Set temperature + 2F Cooling

Set temperature – 2F < Room temperature Set temperature + 2F Monitoring mode (*1)

Room temperature < Set temperature – 2F Heating

*1: If the difference between the room temperature and set temperature is small when operation starts, the cooling thermostat remains in standby status (OFF) until the temperature difference increases. When the temperature differ- ence increases, either cooling operation or heating operation is selected. This standby status is known as “monitoring mode.”

(2)After operation starts in the selected operating mode, the set temperature is automatically shifted by + 4°F (2°C) (cooling operation) or – 4°F (2°C) (heating operation).

Example: Temperature set on the remote controller is 68°F (20°C).

	Selected operating mode	Shifted set temp.	Remote controller display
1	Cooling	72°F (22°C)	68°F (20°C)
2	Heating	64°F (18°C)	68°F (20°C)

(3)Operating mode changes (heating cooling, cooling heating) which occur during operation as a result of temperature changes are handled as shown below.

Heating cooling: Room temperature Shifted set temperature (set temperature + 4F (2°C)) + 1F (0.5°C)

Cooling heating: Room temperature Shifted set temperature (set temperature – 4F (2°C)) – 2F (1.0°C)

Example: Temperature set on the remote controller is 68°F (20°C).

	Operating mode change		Shifted set temp.
1	Heating	Cooling	68 + 4 + 1 = 73°F or higher (20 + 2 + 0.5 = 22.5°C or higher) (*2)
2	Cooling	Heating	68 – 4 – 2 = 62°F or lower (20 – 2 – 1.0=17.0°C or lower)

*2: During heating operation when the body sensor is used, a temperature shift is applied to the intake temperature
detected by the sensor, in consideration for the difference in temperature at the top and bottom of the room. (Refer				2
to the “Room Temperature Control” item.) If this intake shift temperature is 8°F (– 13°C), then the heating cooling
change occurs when the temperature detected by the body sensor is 80°F (26.5°C) or higher.				2
(4) Cooling (heating) operation does not change if the room temperature changes from area C A (or A C) within 10
minutes after the compressor turns OFF. (Monitoring mode is excepted.)
(5) When the heating/cooling change
occurs, the 4-way valve switches				3
