Setting a Thermostat Jumper for
Dehumidification Operation
To control a MISC output for dehumidification, install the Humidity
Module and place the Humidity Jumper on HUM (see page 9.2).
Then place the MISC1, MISC2, or MISC3 jumper on the terminal
labeled DEHUM (see diagram below). This will supply 24VAC to the
selected MISC terminal based on the programming in the following
pages. Only one of the three outputs (MISC1, MISC2, or MISC3) is
required to have a jumper. For more information regarding the MISC1,
MISC2, and MISC3 outputs, please see section 17.
In the diagram below, the MISC2 jumper has
10
been set for DEHUM (dehumidification) operation.
