For additional flexibility, your thermostat has three configurable
outputs. These outputs are designed to have different functions /
depending on how the jumpers are set (below).
Each output, labeled MISC1, MISC2, and MISC3 may be set for one
of the six choices available.
In the diagram below, the MISC3 jumper has been set for HUM*
(humidification) operation, the MISC2 jumper has been set for
DEHUM* (dehumidification) operation, and the MISC1 jumper has
been set for PROG (programmable) operation.

W3 JUMPER SETTING
If thejumper 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 M ULT]-STAGE OPERAT]ON EXPLA]NED - SECT]ON 13 of the Owner's
Manual
The 3rd Stage of Heat is turned on when:
(A) The 1st and 2rid stages have been on for the time required (steps 27
and 28, page 13.6). ]t 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

PROG JUMPER SETTING
If the jumper for MISC1, MISC2, or MISC3 is set to PROG the corresponding MISC screw
terminal on the backplate will con trol a pilo t relay or o ther accessory,
PROGRAMMABLE OUTPUT - SECTION 14 of the Owner's Manual
This jumper setting allows the M]SC outputs to control a pilot relay by time,
temperature, or a signal from the ]nternet/Phone, The foilowing are three
possible scenarios:
By Time: A device that requires a start and stop time An example
of this would be an exterior tighting 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

HUM JUMPER SETTING
If the jumper for MISC1, MISC2, or MISC3 is set to HUM, the corresponding MISC screw
terminal on the backplate will control a humidification system,
HUMIDIFICATION OPERATION - SECTION 9 of the Owner's Manual
If your HVAC unit is equipped with a humidification system and the Humidity
Module (sold separately) has been installed, the thermostat will provide power
to the MISC1, MISC2, or MISC3 terminal of the thermostat when the humidity in
the home falls below the humidity setpoint you have chosen. The value for this
setpoint ranges from 0% to 60%. If no humidity is desired or if a humidification
system has not been installed, set the value to OFR
DEHUM JUMPER SETTING
If the jumper for MISC1, MISC2, or MISC3 is set to DEHUM, the corresponding MISC screw
terminal on the backplate will be connected to the dehumidification terminal of a furnace board.
NOTE: Not all furnaces have a dehumidification terminal,
DEHUMIDIFICATION OPERATION - SECTION 10 of the Owners Manual
If your HVAC unit is equipped with a dehumidification system the thermostat will
operate in one of two ways,
1) Normally Closed (NC): The thermostat wifl de-energize the MISC1, MISC2,
or MISC3 terminal of the thermostat (this MISC terminal is connected to the
DEHUM terminal on your furnace) to allow the fan to run in low speed when
the humidity in the home is above the dehumidify setpeint you have chosen
and there is a call for 1st stage cooling
2) Normally Open (NO): The thermostat will energize the MISC1, MISC2, or
MISC3 terminal of the thermostat (this MISC terminal is connected to the
DEHUM terminal on your furnace) to allow the fan to run in tow speed when
the humidity in the home is above the dehumidify setpoint you have chosen
and there is a call for 1st stage cooling
