What HA2
actually means.
HA2 is CellarPro's condenser overheat alarm. It means the heat pulled from the cellar is not leaving the condenser: the coil or filter is dirty, the vents are blocked, the condenser fan is not turning, or the room behind the unit is too hot or too small. On a new installation CellarPro points first to ventilation and clearance; on a unit that has run fine for months, to a dirty coil.

What to do when HA2 shows on the wine cellar cooling unitKind of codeFans and airflow
A fan the controller counts on is slow, noisy or stopped. On the cellar side one fan pushes cool air across the racks; on the exhaust side, or in a split system's outdoor condenser, another throws the room's heat away. A rack or a case of wine stacked against the grille, a clogged filter, a dust-caked condenser or a tired capacitor is cleared before a motor is replaced.

Restoring the two fans a cellar unit depends on: the one that moves cellar air across the cold coil and the one that throws the heat away.

A cellar cooling unit exhaust overheating makes the room on the other side of the wall uncomfortably warm, blows hot air hard enough to feel from across the room, and often makes the unit stop and restart in the afternoon.

Before you book,
in this order.
Each step comes from CellarPro's own guidance for HA2 on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit.
Clean the condenser coil or filter at the rear of the unit, with the unit unplugged; CellarPro advises a vacuum or brush, not compressed air.
Remove anything blocking the intake or exhaust, including a louvered grille on a ducted unit.
Check that the condenser fan turns when the unit runs.
In hot weather, raise the minimum setpoint to 60°F until temperatures ease; if HA2 keeps returning, book a visit.

What not to do
HA2 is not the cellar temperature alarm; the cellar may still be fine when it first appears. On a split system it refers to the outdoor or remote condensing unit, not the evaporator in the cellar.

Through-the-wall cellar cooling unit
A self-contained box set into an opening in the cellar wall: its cold face blows into the wine room, and its warm face breathes out into the room next door.
Ducted cellar cooling unit
A self-contained cooling unit placed outside the cellar, in a mechanical room, attic or basement, that sends chilled air in and takes return air back through insulated ducts.
Split-system cellar cooling
An evaporator inside or beside the cellar and a condensing unit outside or in another room, joined by an insulated copper line set and charged on site.
In CellarPro's own words
The condenser temperature is too high (above 140°F for 2 hours)

When you book, type the code or the blink count as the controller shows it, add the full model number, and say what the thermometer in the cellar reads now — that gives the technician a head start.
