1-2. HEATING OPERATION
1-2-1 HEATING CAPACITY CONTROL
A sensor (room temperature thermistor) built in the indoor unit will usually perceive
difference or variation between a set temperature and present room temperature, and
controls the operation frequency of the compressor.
* If the room temperature is lower 3 degC than a set temperature,
the compressor operation frequency will attain to maximum frequency.
* If the room temperature is higher 2.5 degC than a set temperature, the compressor
will be stopped.
* When the room temperature is
between +2.5 degC to -3 degC of the setting temperature,
the compressor frequency is controlled within the range shown in Table2.

The compressor rotation frequency shall change according to set temperature and room
temperature variation which the room temperature sensor of the indoor unit has detected
as shown in the Fig 2.
