to provide air circulation for the system. Connect the R and G
terminals on the furnace to the COM and N.O. terminals on the
HRV. See Fig. 26 for a wiring diagram. Never connect a
120-vac circuit to the terminals of the HRV control contacts.
Use only low-voltage furnace blower control contacts.
On some older thermostats, energizing the R and G
terminals at the furnace has the effect of energizing Y at the
thermostat and therefore energizing the cooling system. For
these thermostats, use the alternate control contacts wiring. See
Fig. 27.
