Alarm icon.
When flashing, indicates that a Zone is in an alarm state. When steadily illumi-
nated, indicates that an alarm condition exists, but the programmed time delay
interval has not yet elapsed. When time delay period elapses, the icon will begin
flashing.
11
Delay Time Entry Mode icon.
During programming, indicates selection of delay time mode (up to 120 minutes
delay can be entered). When icon appears, a delay time (in minutes) can be
entered. With a delay programmed for the Zone, conditions exceeding the pro-
grammed limits (such as during a defrost cycle) are ignored for the duration of
the programmed delay.
This function is typically used to prevent false alarms for freezers and coolers
that have defrost cycles or doors that are opened frequently.
