Temperature Out of Range
Should any of the temperatures go out of the preset
range for any of the zones, power to the heated com-
ponents is interrupted, and the HIGH TEMPERA-
TURE ALARM light (AD) goes ON. The alarm auto-
matically goes OFF and the system resets when the
temperature is back in range. The HIGH TEMPERA-
TURE ALARM will activate at 40
F (22 C) over the set
value (SV).
