Setting a Thermostat Jumper for
Humidity Operation
NEVER PUT MORE THAN ONE JUMPER
ON THE SAME MISC JUMPER BLOCK!
THIS MAY DAMAGE THE THERMOSTAT
To operate one of the MISC outputs using humidity-based operation,
place the MISC1, MISC2, or MISC3 jumper on the terminal labeled
HUM (see diagram below). This will supply 24VAC to the selected
MISC terminal based on the humidification programming in the
following pages. Only one of the three outputs (MISC1, MISC2, or
MISC3) is required to have this jumper. For more information
regarding the MISC1, MISC2, and MISC3 outputs, please see
section 21.
