Controller Alarm Signals
The controllers come with a set of alarm messages, which show in the display when something, pos-
sibly wrong with the cabinet or controller. The message will display until the alarm condition recovers.
All alarm conditions flash alternating between the alarm and the cabinet (zone) temperature, except for
a cabinet (zone) probe failure.

check probe connections and resistance before replacing the probe.

od of programming is through the replacement of the controller for a beverage center, a refrigerator or
a wine cellar, all look the same in appearance but there are three different part numbers.
