SYSTEM OPERATION:
Standard and Remote Controllers
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 tempera- tures (below 120°F for the evaporator and condenser). When the evaporator and condenser fans are activat- ed 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 differential of 1°F), the unit will turn off. 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 fine tune the controls. Feature is off 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 off 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.
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 when the evaporator temperature reaches 26°. Dur- ing the defrost cycle, the indoor fan will provide air flow across the indoor coil, which will evaporate any frost accumulation.
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).
