Sanyo KMS1872 Manuale Utente

During COOL or DRY operation, freezing is detected and 
operation is stopped when the temperature of the indoor heat 
exchanger matches the conditions below.
1. Freeze-prevention operation is engaged when the 

temperature of the indoor heat exchanger is below 43°F(6°C).

2. Restart after freeze-prevention operation occurs when the 

temperature of the indoor heat exchanger reaches 46°F(8°C) 
or above.

a.

 Area: Automatic capacity control

b.

 When the temperature drops below Point A, the operation 

frequency is reduced by a certain proportion.

c.

 Area: Frequency increase is prohibited.

d.

 When the temperature reaches Point C or above, freezing 

prevention is ended and control is the same as in the 

a

 area.

 When the temperature drops to below 36°F(2°C) (continuously 

for 2 minutes or longer), the compressor stops.

     Once the freeze condition is detected, the air conditioner will 

work less than the maximum frequency until it is turned off.

The Freeze Prevention Control during the Low Ambient Cooling 
Mode (outside air temperature:59°F(15°C) or lower) is as follows.
The compressor stops when the temperature of indoor heat 
exchanger becomes less than 36°F(2°C).
The compressor restarts when the temperature of indoor heat 
exchanger becomes 46°F(8°C) or higher.
