i have an old furnasman gas furnace.
It has AC
there is a honeywell transformer screwed on to the electrical connection
enclosure i suspect it was installed when the ac was installed.
I want to replace the fan motor with a 2 speed one
i want to add a switch to the furnace so i can have the fan on all the
time in slow speed. then when the burner or the ac comes on it will
change to high speed.
is there a relay i can install to do this or is there something else i
need to do.
I think many (most? all?) furnace/AC combinations already incorporate
dual speed fans. Are you sure it doesn't already have the capability
you seek? You might just need an appropriate thermostat.
