Viking VCWB300 specification

Showroom mode: This mode, selected by closing the showroom switch is intended to simulate normal operation in all ways except the cooling and temperature alarm functions. Closure of this switch will over-ride normal cooling. Temperature displayed for the chambers will be the last temperatures stored in memory, or the factory defaults setting if they have not been changed. Lights and functions will occur as in normal cooling operation described above.

Holiday mode (Sabbath mode): Pressing and holding the display button continuously for 10

seconds accesses this mode. (Note: The Display must be “on” before entering Holiday Mode.) To cancel Holiday Mode, press and hold the display button continuously for 10 seconds. When Holiday Mode is selected, a random time delay of 15 to 25 seconds will be applied to the compressor relay start and stop. The chamber lights relay will remain de-energized. The display will not be illuminated. Audible sound (beep) from the control will be disabled. Fan outputs will not be affected by opening or closing of the door switch. All front panel buttons will be inoperative except a 10 second press of the display button causing the control to exit Holiday Mode. All other functions will continue as in normal cooling described above. The Alarm sounds is disabled and the home security relay will not transfer.

Service mode: This mode, selected by pressing and holding zone, higher temp and lights buttons simultaneously for 5 seconds is intended for manual operation of the compressor, valves and fans for purposed of servicing / diagnosing and repair. When put in to this mode, valve 1 will energize for 10 seconds to relieve any pressures in the system. The compressor will then energize and continue to run continuously while in service mode. Pressing the zone button will change which chamber is active as indicated on the display. The solenoid valve and evaporator fan will energize in the chamber that is active. To leave the service mode, press and hold the zone higher temperature and lights buttons simultaneously for 5 seconds, normal operation will then resume.

Charge mode: Pressing the lower temp button while in service mode selects charge mode. In this mode all zone valves are open and all other functions are “off”. This is to vacuum, evacuate and charge the sealed system. To exit charge mode the power must be removed, turn “off” the power switch or unplug the product.

Display interface board: Mode of operation: Interface board for Vacuum fluorescent display module.

During normal operation, temperatures in all three chambers are displayed and the red lens is blinking approximately once per second when the RS-232 signal is being received. A “bar” symbol is displayed over the “active” temperature reading. The “adjusted” temperature will be displayed as blinking, approximately .5 seconds on .5 seconds off.

When the “alarm mode enabled” signal is being received the “alarm” symbol will be displayed. If the “alarm” signal is being received, the “alarm” word will be displayed for approximately 4 seconds and the chamber temperature will be displayed for the next 4 seconds. The piezoelectric sounder will turn on for 100 milliseconds, approximately every 8 seconds. The display will be on, even if the “display blank” command is being received.
