Setting a Thermostat Jumper for
Humidity Operation
NEVER PUT MORE THAN ONE JUMPER
ON THE SAME MISC JUMPER BLOCK!
THIS MAY DAMAGE THE THERMOSTAT
AND VOID YOUR WARRANTY
To control a MISC output for humidification, 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.
