Important Note:
When the Lighting Delay Switch is first activated –
A. If a time switch is connected and is set to ON,
the main load will remain ON.
B. If no time switch is used or if one is connected
but is set to OFF, the main load will turn ON for
10 minutes. At the end of the 10 minute period,
the warning circuit turns on for 4 seconds, 1
minute, or 5 minutes. The main load will remain
ON for the 1 or 5 minute warning period. If an
extension of time is required for the main load,
press the remote ON button momentarily, the
warning circuit will turn off, and the main load
will remain on for an additional 1/2 - 12 hour
extension of time.
