PROG JUMPER SETTING
If the jumper for MISC1, MISC2, or MISC3 is set to PROG, the corresponding MISC screw
terminal on the backplate will control a pilot relay or other accessory.
PROGRAMMABLE OUTPUT - SECTION 15
This jumper setting allows the MISC outputs to control a pilot relay by time,
temperature, or a signal from the Internet/Phone. The following are three
possible scenarios:
By Time: A device that requires a start and stop time. An example
21
of this would be a exterior lighting system that needed to be
energized every day between the hours of 8pm and 1am.
By Temperature: An exhaust fan that needs to energize whenever
the temperature from RS2 rises above 90 degrees F.
By Remote: Remotely arming a security system through the web or phone.
