Configuring the Jumpers Configuring the Jumpers
Page 17.2
For additional flexibility, your thermostat has three configurable
outputs. These outputs are designed to have different functions
depending on how the jumpers are set (
below ).
Each output, labeled MISC1, MISC2, and MISC3 may be set for one
of the four choices available.
In the diagram below, the MISC3 jumper has been set for HUM*
(humidification) operation, the MISC2 jumper has been set for
DEHUM* (dehumidification) operation, and the MISC1 jumper has
been set for Y2 (second stage cooling) operation.
NEVER PUT MORE THAN
ONE JUMPER ON THE SAME
MISC JUMPER BLOCK!
DOING SO MAY DAMAGE
YOUR THERMOSTAT.
