When using the ControlAir 15 relay contacts to initiate blower operation on a

furnace, certain thermostats will initiate the outdoor cooling condenser when
R and G are closed.

Use this wiring configuration to stop the ControlAir15 relay contacts from initializing the
condenser unit. This problem can occur at the thermostat because the Y terminal is
connected to the G terminal internal to the stat. When R and G are closed at the furnace
(by dehumidistat or relay) 24 Volts is sent to G at thermostat. 24 Volts is then sent through
Y which will initiate outdoor condenser.
