SYSTEM OPERATION
Initial Start-Up
When power is applied to the unit, the snowflake symbol
will be displayed (if unit is calling for cooling) . There may be
a delay of up to 60 seconds before the evaporator fan turns
on . When the evaporator fan is activated, the fan symbol will
display .
APST (Advance Product Safety Technology) is a temperature
control feature for the evaporator fan that comes standard
with all CellarCool units . APST 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 .
Set Point
The set point is set at the factory (CellarCool) to 55°F . It can be
adjusted by the customer between 50–67°F in one-degree
increments .
Humidity Features
The Fon ("fan on") 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 . When the bottle probe has reached the set point (all
units are shipped with the set point of 55°F and a differential
of 1°), the compressor and the condenser fan will turn off, but
the indoor fan will continue to run for about 5 minutes to
reintroduce any moisture from the evaporator coil . All units
come with this feature turned off . If low humidity is a problem,
increasing "fan on" time will raise the humidity level .
Anti-Short Cycle
The Anti-Short Cycle ensures that the compressor will remain
off for a period of three minutes after the unit has reached
the set point to allow the pressure in the refrigeration unit to
equalize prior to starting the compressor .
Anti-Frost Cycle (defrost)
When the evaporator probe senses a temperature of 26°F
for five minutes, the unit will go into an Anti-Frost Cycle . This
will shut down the compressor and allow the evaporator and
condenser fans to run to evaporate any frost accumulation on
the coil . The compressor will remain off until the evaporator
coil reaches 40°F, or for a maximum of ten minutes . The unit
will then return to normal operation .
Bottle Probe Failure Protection
In the event that a bottle probe should fail, the APST (Advance
Product Safety Technology) will automatically transition
the compressor to a pre-determined time cycle (based
on detailed laboratory testing), which will ensure that the
product is kept within a safe temperature range .
Display
The bottle probe temperature is displayed by default . “Def”
is displayed during Anti-Frost . The air sensing probe and
evaporator probe temperatures can be accessed by pushing
the SET button and scrolling through “PB1” (bottle probe), and
“PB2” (evaporator probe) .
Safety Features
Once the compressor relay is de-energized the controller must
wait five minutes before reenergizing the relay . This prevents
the compressor from repeatedly turning off and on . If the unit
is calling for cooling during this time, the compressor symbol
will blink, indicating that cooling is needed but the control is
waiting for the Anti-Short Cycle delay .
In the event of a faulty bottle probe, the compressor will
cycle off for 10 minutes and on for 40 minutes . “P1” will be
displayed on the screen .
