and appropriate zone valve based upon the temperature at the evaporator thermistor and will turn off the zone valve based upon the temperature at the chamber thermistor.

Temperature readout and setting: Pressing the zone button will change which chamber is selected for adjustments. The selected chamber will have a bar displayed over the temperature reading on the VFD. Pressing the higher or lower buttons will raise or lower the set point of the selected chamber in one degree F increments. Every time any set point is changed a “set time” delay will start. When the “set time” delay is completed without another change in the temperature the currently displayed number will become the new set point. The new set point will be stored in non-volatile memory. The unit will begin controlling the particular chamber to the new set point, and the actual chamber temperature will be displayed. Temperature can be displayed in either Degrees F (default) or in Degrees C. It can be changed from one to the other by pressing and holding both the display on/off and the display alarm buttons simultaneously for 5 seconds. The display will show “F” or “C” appropriately. This setting will be stored in non-volatile memory and will be saved during period of power loss.

Display off: To turn the display off, momentarily press the display. The display will turn off as soon as the button is released.

To turn the display on, momentarily press the display button. The display will turn on as soon as the button is released.

Compressor protection: At any time the compressor needs to start, including that power up the appropriate zone valve will energize for 60 seconds before the compressor is allowed to start. This is intended to allow to discharge any pressures in the system so that the compressor will not start under heavy load. Any time that all chambers reach set temperatures(s), the compressor will continue to run for an additional 30 seconds. This is intended to reduce compressor start / stop cycles as the various chambers call for cooling.

Fan operation: The evaporator fans, if running will shut off whenever the door switch opens and turns back on when the door switch closes. When operating in Holiday Mode the Fan(s) will not turn off, if running, when the door switch opens.

Chamber lighting: The light inside the chambers can be always on, or only on when the door switch is open. Pressing the lights button on the front panel toggles this setting. Also see holiday mode.

Alarm security: Alarm operation can be toggled on or off by pressing the alarm front panel button for 2 seconds. When the temperature inside any chamber is higher than the set temperature by more than 5 degrees F for longer than the “2 hours” delay, the display will flash on and off and an audible signal will sound. When the alarm mode is active, an enunciator will appear in the display. Upon initial power-up, the alarm will be disabled for a start-up delay to allow for the unit to reach temperature. The alarm can be disabled by pressing the alarm off button. A door alarm is provided that will sound if the door switch is open for longer than the door alarm delay. The alarm will shut off upon re- closing the door and the delay time will be reset. Temperature alarm operation will be inhibited in show room mode. Home security contacts will transfer during an alarm condition. When operating in Holiday Mode, the high temperature alarm and door alarms are disabled.
