Explanation of Jumper Settings

W3 JUMPER SETTING

If the jumper for MISC1, MISC2, or MISC3 is set to W3, the corresponding MISC screw terminal on the backplate will control a third stage of heat.

W3 MULTI-STAGE OPERATION EXPLAINED - PAGE 13.4

The 3rd Stage of Heat is turned on when:

(A)The 1st and 2nd stages have been on for the time required (steps 27

and 28, page 13.6). It is adjustable from 0-60 minutes and the default And is two minutes.

(B)The temperature from the setpoint is equal to or greater than: the set- point plus the 1st stage deadband (step #24, 13.5), plus the 2nd stage deadband (step #25, 13.5) plus the 3rd stage deadband (step #26, 13.5). This 3rd stage deadband is adjustable from 0-10 degrees and the default is two degrees.

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 14

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. For example, 21 an 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 RS1 rises above 90 degrees F.

By Remote: Remotely arming a security system through the web or phone.
