SYSTEM OPERATION: STANDARD & REMOTE
Initial Start-Up
When power is applied to the unit, the control will briefly 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, as the fans will not turn on until the sensors reach their perspective start tem- peratures (below 70°F for the evaporator and above 80°F for the condenser). When the condenser fan is activated the “AUX” symbol will turn off, and when the evaporator fan is activated the “FAN” symbol will turn on. The temperature control feature for the evapora- tor fan is a feature applicable to Whisperkool Advance Product Safety Technology (APST), which ensures that in the possible event of a cooling deficiency, the heat from the indoor fan will not raise the heat of the wine cellar, which could otherwise have an adverse effect on the wine aging process. After the indoor coil reaches a temperature below 70°F, the indoor fan symbol will be displayed and the fan will turn on. Note: For remote system condenser fan cycles with the compressor, the “Aux” symbol does not apply.
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, 1 minute off until the unit gets a call for cooling which is a feature of the WhisperKOOL Humidity Management (WHM) system. The WHM is an adjustable feature which allows the customer the convenience 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 fine tune the controls.
Anti Short Cycle
The Anti Short Cycle ensures that the compressor will remain 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.
Defrost Cycle
The Defrost 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 unit is installed in a
Note: Remote control systems do not use condenser fan cycling.
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
Remote Control Panel (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 flexibility for installing the Extreme Series cooling unit in your wine cellar. The remote option must be specified 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 fit standard ventilation ducting allowing the installer to vent air to and from the unit for optimum performance (please see specifications for details).
