I wish to run the fan without heat to circulate air thought the house.
I am using a Honeywell programmable thermostat with a manual and auto switch.
When the furnace was installed in 1994 I recall being told that the unit needed an accessory PCB in order to just blow air.
Is this recollection correct and, if so, what is the PN of the part I need to get from Lennox?
If not, is there another way to rig the unit to just blow air?
Nobody special

Perhaps you do not have enough conductors between the furnace and your stat. It has standard terminals so no extra board is required.
If you have an extra stat wire connect it to "G" at your stat and the furnace.
A 1994 furnace with no induced draft motor, wow.
"Tip of the Day" Remember to remove power first.
