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.

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
