8. Deice Control
FU Deicing operation is controlled by timer and sensing the indoor pipe temperature.
fU Deicing operation checks the indoor pipe temperature and Intake-air temperature at 25 minutes and 60 minutes
on starting of heating operation, and discriminates by temperature difference.
fu When the heating operation passed 25 minutes, the temperature (; T1=TE1-TR1) is checked and memorized
with checking the indoor pipe temperture (TE1) and the indoor Intake-air temperature (TR1).
fU When the heating operation passed 60 minutes, deicing operation checks the indoor pipe temperature (TE2)
and the indoor Intake-air temperature (1TR2), and checks indoor pipe temperature(TE2), the temperature
difference (; T2=1E2-1R2) and the temperature difference ; Td(=; T1-; T2)of ; T1, ; T2.
If temperature of indoor pipe is below 32°C Deicing function operates at the priority | condition.
If temperature of indoor pipe is over 32°C Deicing function operates at the priority || condition.
If the temperature difference (; Td) become more than the option temperature, deicing operation starts.
fU At that time, deicing operation time is decided.
fU The deicing operation time starts after deicing operation started.
FU If deicing operation start, above heating operation time is reset, so if deicing operation is finished, the heating
operation time is recounted.
fU The deicinig time and the operation diagram are as following.

9. Soft Dry Operation.
During Soft Dry Operation, the compressor ON temperature is the setting temperature plus 1°C, the compressor
OFF temperature is the setting temperature minus 0.5°C.
* When the room temperature rises over the compressor ON temperature, the operation mode is switched to the
cooling mode.
* When the room temperature falls between the compressor ON temperature and OFF temperature, the operation
mode is switched to the Soft Dry Operation.
In this temperature range, 10min. Dry operation, 5.5min operation OFF, 1.5min. only fan operation repeat. During
10min Dry operation, even if the room temperature falls below compressor OFF temperature, 10min(MAX)
Compressor ON from starting of Dry operation which includes 4 min. Compressor ON operation below the com-
pressor OFF temperature.
