The EF-6 duct fan works fine. The PS1503 Airstat switch I'm having trouble with. I've moved it three times and adjusted it to be perfectly vertical to no avail. If I tap it while the furnace blower is on, the switch functions and the duct fan goes on. I'll play with it a bit more, but I'm quite disappointed. If I continue to have issues, I'll have my furnace guy hook the booster fan up directly with the furnace blower. If that is necessary, the switch will have been a waste of money and time.
