Wiring Thermostats
Run wire from the VisionPRO® IAQ Thermostat 1, 2, 3
terminals to the corresponding terminals on any one of the
EnviraCom bus terminal sets. More than one thermostat can
be connected to a bus terminal. See Fig. 3.
Wiring Equipment
CONVENTIONAL EQUIPMENT
Connect the first stage heat to W1/E, second stage heat to W2,
and third stage heat to W3/Aux. Wire first stage cooling to Y1,
and second stage cooling to Y2. See Fig. 3.

If separate HVAC equipment transformers are used for the
heating and cooling systems, such as for an oil furnace, wire
the heating transformer hot wire to Rh and the cooling
transformer hot wire to Rc. Locate the Rh/Rc jumper above the
equipment terminals and remove the jumper to expose the two
pins.
HEAT PUMP EQUIPMENT
Connect the Y1 terminal to the first stage compressor, and the
Y2 terminal to the second stage compressor. W3/Aux is the
auxiliary heat and W1/E is the emergency heat. If emergency
heat and auxiliary heat use the same piece of equipment,
place a jumper from W3/Aux to W1/E and wire it to the resistive
heat equipment. See Fig. 4 and 5. See Fig. 6 and 7 for two-
stage heat pump equipment.
