Wiring IAQ Equipment or a Heat/Cool Stage to the Universal Terminals

To Equipment Interface Module

“U” terminals can be used for humidification, dehumidification or ventilation.

Fig. 339. Wiring a powered humidifier.

Fig. 340. Wiring a powered ventilator.

Fig. 341. Wiring a powered dehumidifier (whole house

dehumidifer).

Fig. 342. Wiring a non-powered humidifier.

Fig. 343. Wiring a non-powered ventilator.

Fig. 344. Wiring a low speed fan for dehumidification.

1Any combination of universal relays (U1, U2, U3) can be used. They are set in the thermostat installer setup.

2Wire the universal EIM relay to the low speed fan for dehumidification control at the equipment. The EIM relay can be set to be

normally open or normally closed in the thermostat installer setup.
