Connections are made via the “HUM” quick connects. The humidifier output is on whenever a heating demand is being satisfied. The contacts of this output are isolated to allow application of 24 VAC or 115 VAC to one terminal and the humidifier load to the other. Connect an auxiliary Electronic Air Cleaner; rating shall be max 1.0 Amp @ 115 VAC. This output is energized whenever any of the four blower speeds are energized. Connections are made via 0.250 x 0.032” male quick connect terminals labeled "EAC" and "N3". Connect an auxiliary UV lamp (if required); rating shall be max 1.0 Amp @ 115 VAC. This output is energized whenever any of the four blower speeds are energized. Connections are made via 0.250 x 0.032” male quick connect terminals labeled "UV" and "N2". Can accomodate most brands of evaporator A-coil for cooling applications.
