Configuring the Jumpers
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 five 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 PROG (programmable) operation.
