5.1.4. OPERATION PROCEDURE FOR AUTOMATIC COOLING / HEATING OPERATION
The automatic cooling/heating operation is required to be set by the optional function. Contact
your distributor or dealer of HITACHI for detailed information.
This function is to change operation mode, cooling or heating automatically according to the
temperature difference between the set temperature and the suction air temperature.
In the case that the suction air temperature is higher than the set temperature by 3 C,
the operation is changed to COOL mode, and lower than the set temperature by 3 C, the
operation is changed to HEAT mode.
NOTE:
In case of heating operation at the LOW fan speed, the operation often stops by the
operation of the protective devices. In this case, set the fan speed to HIGH or MED.
In case that the outdoor temperature is higher than approximately 21°C, the heating
operation is not available.
The temperature difference between cooling and heating operation is quite big in case of
using this function. Therefore, this function can not be used for the air conditioning of the
room where requires accurate control of temperature and humidity.
