Initial Start-Up
When power is applied to the unit, the control will
briefly display all symbols, and the Compressor
symbol will be displayed (if unit is calling for cooling).
There may be a brief delay prior to the evaporator
and condenser fans turning on.
Normal System Cycle
After the bottle probe has reached the set point (all
units are shipped with the set point of 55°F and a dif-
ferential of 1°F) the unit turns off. The WHM is an ad-
justable feature which allows the customer the con-
venience of managing the humidity enhancement
of their wine cellar. The WHM is one of the many
Customer Preference Selection features which allow
the customer the ability to fine tune the controls. This
feature is set to 0 when shipped but if needed can be
adjusted.
Anti Short Cycle
The Anti Short Cycle ensures that the unit will remain
off for a period of 3 minutes after the unit has reached
the set point to allow the pressure in the refrigeration
system to equalize prior to starting the compressor.
Anti Frost Cycle
The Anti Frost Cycle is a precautionary measure, as
icing or frosting of the coil does not occur during
normal operation. The system will go through an
anti frost cycle when the evaporator temperature
reaches 26°. During the Anti Frost cycle, the unit will
stop cooling and run the indoor fan to provide air
flow across the indoor coil, which will melt any frost
accumulation.
Bottle Probe Failure Protection
In the event that a bottle probe should fail, the APST
(Advance Product Safety Technology) will automati-
cally transition the Refrigeration Compressor cycles
to a pre-determined time series (based on detailed
laboratory testing), which will ensure that the prod-
uct is kept within the safe range.
