HA Alarm / Runs Constantly


CellarPro Runs Constantly (HA Alarm)



The cooling capacity of the cooling unit depends on the thermal load on the wine cellar, and the resulting BTU that is required to cool and maintain the cellar at the desired temperature. Our cooling capacities were calculated based on the following assumptions:
  • Wine Cabinets: R-12 Insulation and up to 95 degrees ambient temperature. If the ambient temperature outside your cellar is higher than 85 degrees, you will need more insulation and/or additional cooling capacity from a more powerful unit.  For a given size wine cabinet, refer to the following chart for more information: Wine Cabinet Cooling Capacity
  • Wine Cellars:  Assuming the proper construction of a wine cellar with a vapor barrier, its size, Insulation (R Value) and ambient temperatures will affect the cooling capacity of the cooling unit.  We have published several tables for various size wine cellars - for more information, please click on the appropriate table in the following link::  Cooling Unit Buying Guides.
CellarPro wine cooling units are designed to turn on when the air temperature in the cellar rises above the Minimum Set Point + Temperature Differential, and turn off when the air temperature falls below the Minimum Set Point. For example, if the Minimum Set Point is 58°F and the Temperature Differential is 4°F, the cooling unit will turn on above 62°F and turn off below 58°F. 

When bottles are first loaded in the cellar, the cooling unit will run continuously (even up to a week) until the temperature inside the cellar falls below the Set Point.

Hot weather conditions, insufficient insulation, inadequate ventilation, lack of a vapor barrier, mis-sized cooling units, external sources of load, and/or dirty condenser coils can all cause the cooling unit to run continuously.

If your CellarPro wine cooling unit runs constantly or is getting an HA Alarm, try the following:

  • Clean the condenser coils
  • Check the ambient temperature in the space outside the condenser coils while the cooling unit is running
  • Increase the supply of cool air to the space outside the condenser coils, using a fan, ducting or an exhaust system to remove heat from the space.
  • Make sure that the cooling unit is NOT in Energy-Saver Mode
  • Confirm that the cooling unit is sized appropriately for the space it is trying to cool
  • Turn off or remove any sources of heat load (eg wine coolers, steam humidifiers, certain lighting, etc)  
  • Check to see if the cooling unit is producing a lot of moisture
