To control a MISC output for dehumidification, 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.
