degrees F (-4 to -7 Deg C) colder. As the cellar temperature decrease to 55 degrees F (13 Deg
C), the supply temperature differential decreases 8 to 12 degrees F colder.
NOTE: The remote interface controller will show a "Hi Temp" fault until the wine cellar
temperature falls below 65 deg. F (18 Deg C) . See page 40 for Hi Temp Alarm

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 Extreme Climate Protection, 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 Thermostat

Normal settings are between 54 and 58 degrees F (12 and 14 Deg 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 3
degrees F.

Regulating the Wine Cellar Temperature

Wine cellars have a natural temperature gradient of approximately 5 to 10 degrees F (-15 to -12
Deg 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.
NOTE: To monitor the cellar temperature, place thermometers in various locations
in the cellar to monitor the temperature zones. Change the temperature in various
zones by shifting the air flow patterns.

Changing the Air Flow Direction

The grilles furnished with Wine Guardian are single directional. Rotate the grilles to change the
direction of the air flow.
When using multiple supply ductwork, balance the air flow between the ductwork. If too much air
flows though one duct but not enough air flows from the other duct, install a damper or other
restriction into the duct with too much air. That will force more air to flow out the other duct.
