Functions for FDMQ Series SiUS091601EA67 Part 4 Functions and Control3.2 Program Dry OperationOutline Program dry operation removes humidity while preventing the room temperature from lowering.Since the microcomputer controls both the temperature and airflow rate, the temperatureadjustment and FAN setting buttons are inoperable.Details The microcomputer automatically sets the temperature and airflow rate. The difference betweenthe room thermistor temperature at start-up and the target temperature is divided into two zones.Then, the unit operates in an appropriate capacity for each zone to maintain the temperature andhumidity at a comfortable level.Room thermistortemperature at start-upTarget temperatureXThermostat OFF pointYThermostat ON pointZ24.5°C or more(76.1°F or more) Room thermistortemperature at start-upX – 2.5°C(X – 4.5°F) X – 1.0°C(X – 1.8°F)16.5 ~ 24°C(61.7 ~ 75.2°F)X – 2.0°C(X – 3.6°F)X – 1.0°C(X – 1.8°F)16°C or less(60.8°F or less)16°C(60.8°F)X – 2.0°C(X – 3.6°F)X – 1.0°C = 15°C(X – 1.8°F = 59°F)Zone A = Thermostat OFFTarget temperature XZone BRoom temperature Room temperatureZone C = Thermostat ONY = X – 2.5°C (4.5°F)orY = X – 2.0°C (3.6°F)Z = X – 1.0°C (1.8°F)X – 1.0°C (1.8°F)(R23000)
