To operate one of the MISC outputs using dehumidification-based
operation, 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 program-
ming 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.
