SiUS331604E Outline of Control (Indoor Unit)Functions and Control 546.2.2 With the Optional Infrared Floor SensorThe relationship between remote controller set temperature and control target temperature is described below.• The temperature difference for cooling ⇔ heating mode switching is 5°C (9°F).• When using the floor temperature as the control target, the remote controller set temperature is equal to theactual control target temperature in heating operation.• The above also applies to automatic operation. When setting the suction air thermistor (Default setting) When using the remote controller thermistor (Field setting is required)Examples are given to illustrate a control target temperature that satisfies the remote controller set temperature.Regarding control target temperatureWhen using the infrared floor sensor, the temperature around people will be treated as the control targettemperature for operation.What is the temperature around people?The temperature around people refers to the temperature of the living space, obtained from the temperaturearound the ceiling and the temperature underfoot. The temperature is calculated using the detected values of thesuction air thermistor and the infrared floor sensor.It is difficult to use only suction air temperature control for underfoot air conditioning.˚CRemote controller set temperatureControl target temperatureRemote controller set temperatureControl target temperatureCoolingHeating˚FTemperatureRemote controller set temperatureControl target temperatureRemote controller set temperatureControl target temperatureCoolingHeating˚C˚FTemperature
