Running the Unit
Check unit to confirm the compressor is running, such as the hum of the
compressor or cool air leaving the unit.

.
Initially, the unit may run continuously for several hours, up to a day or more, while it lowers the
cellar temperature. Once the unit reaches the set point temperature, it shuts off and starts to cycle
on and off as it continues to lower the bottle temperature to the set point. The cellar air reaches
set point before the bottles. If the cellar temperature started at 24°C, the supply air temperature
discharged from the unit will probably be 8°C to 11°C colder. As the cellar temperature decrease
to 13°C, the supply temperature differential decreases 6 to 7°C colder.
NOTE: The remote interface controller will show a “Hi Temp” fault until the wine
cellar temperature falls below 65 degrees. See page 49 for Hi Temp Alarm details.
Cycling the Unit
The fans continue to free-wheel for several minutes when the unit cycles off. This
is normal.
If the unit is furnished with a low ambient control, the condenser fan also cycles on and off
during cooling. This maintains the head pressure on the compressor under low ambient
conditions, and is normal. The bottom of the compressor stays warm even when the unit is off to
keep the lubricating oil warm and separated from the refrigerant.
Setting the Remote Interface Controller
Normal settings are between 12 and 14°C. If the optional heating coil is furnished, enter a
separate temperature setting to maintain the lower setting. To prevent the unit from short cycling,
the setting between heating and cooling cannot be closer than 2°C.
Regulating the Wine Cellar Temperature
Wine cellars have a natural temperature gradient of approximately 3°C between floor and
ceiling. To increase or decrease the temperature in various zones, change the air flow patterns.
To keep the entire wine cellar at the same temperature, set the thermostat to run the supply fan
continuously and not just when the cooling is operating. Set Fan switch to ON instead of AUTO.
