4-1. Control Functions 1. Indoor Air Temprature Control The thermostat is switched on and off in accordance with T shown below. = (Indoor air temperature) - (Temperature set with the remote controller) In the body thermostat mode Indoor air temperature = (Body sensor) - (Shift temperature *) (setting at factory shipment) In the remote controller thermostat mode Indoor air temperature = (Remote controller sensor)
Page 206
2) Maximum and Minimum Frequency Control The compressor's inverter frequency is controlled in accordance with the model and operation mode. The maximum and minimum frequencies for each model are shown in the chart below. There are cases in which frequency is limited with other control functions depending on operational conditions, so operations are not always carried out in accordance with the maximum frequencies listed below.
Page 207
5) Heating High-Load Prevention Control The following control is performed in the heating mode in accordance with the indoor heat exchanger temperature max (E1, E2). (See the chart below.) The operational frequency of the compressor is decreased when the temperature enters the "M" zone. The operation frequency is modified every 30 seconds while the temperature remains in this zone (the thermostat is switched off if it continues for 2 minutes).
Page 208
7) Discharge Temperature Control The following control is performed to prevent the discharge temperature from rising abnormally in order to protect the inverter compressor. In accordance with the temperature of the discharge sensor TD, such controls are performed as to limiting the increase of inverter frequency, decreasing it or halting operation of the compressor.
Page 209
Heating Mask Time This refers to the shortest time that heating operations must be performed without defrosting operations being executed. The mask time for this model is 25 minutes. Defrosting operations will not be commenced until the defrosting mask time has elapsed, even if frost adherence has been detected.

12) Demand Control There are two styles of demand operations available as methods of restraining power consumption. (1) Demand via External Input Demand input from an external source is carried out from the outdoor unit EXCT (CN030) PCB or the outdoor unit's serial/parallel I/O (optional).
