depending on how the jumpers are set (below).

Each output, labeled MISC1, MISC2, and MISC3 may be set for one

of the four 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 Y2 (second stage cooling) operation.

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 will de-energize the M]SC1, M]SC2,

or M]SC3 terminal of the thermostat (this M]SC 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 setpoint you have chosen

and there is a call for 1st stage cooling

2) Normally Open (NO): The thermostat wilt energize the M]SC1, M]SC2, or

M]SC3 terminal of the thermostat (this M]SC 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 setpoint you have chosen
