SYSTEM OPERATION
Initial Start-Up
When power is applied to the unit, the control will briey
display all symbols, and the Snow Flake symbol will be
displayed (if unit is calling for cooling). There may be a
brief delay prior to the evaporator fan turning on. 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 WhisperKOOL.
This is the Advance Product Safety Technology (APST),
which ensures that in the possible event of a cooling
deciency, the heat from the indoor fan will not raise the
temperature of the wine cellar, which could otherwise
have an adverse eect on the wine-aging process.
Normal System Cycle
The FON function is an adjustable feature which allows
the customer the convenience of reintroducing some of
the humidity removed by the fan coil during the cooling
process. The FON Function is a feature that controls the
evaporator fan operation once the set point has been
reached. All units are shipped with the set point of 55°F
and a dierential of 1°F. All units come with this feature
turned o. If low humidity is a problem an increase in this
setting will raise the humidity level. The FON function is
one of the many Customer Preference Selection features
that allow the customer the ability to ne-tune the
controls.
Anti-Short Cycle
The Anti-Short Cycle ensures that the unit will remain o
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ow 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
o. 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 or fan cycling
switch 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 automatically transition the
Refrigeration Compressor cycles to a predetermined time
series (based on detailed laboratory testing), which will
ensure that the product is kept within the safe range.
Remote Keypad (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.
