Configuration

The “System Type” for this thermostat must be set to “Zone Control” under “System Options.” The two

additional outputs (W2 and Y2) are used with zoned heating and cooling systems. The W2 and Y2

terminals control the one control panel mode of operation (heating or cooling). The zone control panel

recognizes calls for heat (W) from the individual zones when the W2 terminal is energized, and calls

for cool (Y) when the Y1 terminal is energized. Neither W2 nor Y2 is energized when the mode is set to

“OFF.” Therefore, the thermostat can act as a Master to set the operating mode of the entire system.
