Initial Start-Up
When power is applied to the unit, the control will
briefly display all symbols, and the Snow Flake
symbol will be displayed (if unit is calling for cool-
ing). There may be a brief delay prior to the evapora-
tor fan turning on, as the fan will not turn on until
the evaporator probe temperature drops to the
perspective start temperature (below 70°F). When
the evaporator fan is activated the Fan symbol will
be displayed. The temperature control feature for
the evaporator fan is a feature applicable to Whis-
perKOOL. This is the Advance Product Safety Tech-
nology (APST), which ensures that in the possible
event of a cooling deficiency, the heat from the
indoor fan will not raise the temperature of the wine
cellar, which could otherwise have an adverse effect
on the wine aging process.
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 compressor and the condenser
fan will turn off, but the indoor fan will continue to
run for about 5 minutes, which is a feature of the
WhisperKOOL Humidity Management (WHM) sys-
tem. The WHM is an adjustable feature which allows
the customer the convenience of managing the hu-
midity 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.
Anti Short Cycle
The Anti Short Cycle ensures that the unit will re-
main off for a period of 5 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 a
defrost cycle every 4 hours. During the defrost cycle,
the indoor fan will provide air flow across the indoor
coil, which will evaporate any frost accumulation.
Low Ambient Conditions
If the condensing unit is installed outside (which will
allow the condenser to be exposed to low ambient
temperatures), the condenser fan may cycle on and
off. The purpose of the fan cycling is to maintain
the system high side pressure, which will ensure
an adequate refrigeration process. The fan cycling
process is accomplished by way of a Johnson Control
attached to the condensing unit.
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.
Remote Control Panel (standard on ducted units)
The remote keypad is designed to give the user the
ability to monitor and change cellar conditions when
the evaporating unit is placed in a remote location
outside of the cellar.
