Initial Start-Up
When power is applied to the unit, the control will
briey display all symbols, and the Compressor sym-
bol will be displayed (if unit is calling for cooling).
There may be a brief delay prior to the evaporator and
condenser fans turning on. When the evaporator and
condenser fans are activated the “FAN” symbol will
turn 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
dierential of 1°F), the unit will turn o. The Whis-
perKOOL Humidity Management (WHM) is an adjust-
able feature which allows the customer the conve-
nience of managing the humidity enhancement of
their wine cellar. The WHM is one of the many Cus-
tomer Preference Selection features which allow the
customer the ability to ne tune the controls. Feature
is o from the factory but can be turned on with the
“FON” parameter.
Anti Short Cycle
The Anti Short Cycle ensures that the compressor
will remain o 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 ow
across the indoor coil, which will melt any frost accu-
mulation.
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 product
is kept within the safe range.
Remote Control (optional)
The control panel can be installed or mounted sepa-
rately from the cooling unit itself (remotely), using the
supplied cable. This option provides unique exibility
for installing the Extreme Series cooling unit in your
wine cellar. The remote option must be specied when
the unit is ordered.
Note: Remote Control is generally standard with a
“Ducted Unit”.
Ducting and Ventilation Options
The ventilation system is ideal for ducting. The option-
al collars t standard ventilation ducting allowing the
installer to vent air to and from the unit for optimum
performance (please see specications for details).
