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 dehumidification 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 21.
