years ago a customer bought an inline booster fan for a similar situation you describe and asked us to install it for him. the fan plugs into a 120v outlet and an air pressure switch with a small tubing gets inserted in the duct senses when the main blower turns on. then starts the booster fan. works the same way as all those fantech dryer booster fans that im sure everyone loves to work on lol. its a cheap and easy "fix" for what u are describing. obviously wiring is better for long term. quick google search found this guy on amazon. maybe something similar would be what ur looking for.good luck.

u/AnotherMadHatter · 5 pointsr/ar15

I have been carrying FENIX flashlights for 6 or so years.

I currently carry the Fenix TX22 2014 edition.

Previously, I carried:

Fenix TK22

Fenix TK21

EDIT: Forgot, I had the Fenix TK15 as well.

Fenix TK12

All of them take 18650 batteries (one of the reasons I bought them). None have failed me due to water/rain (western Washington), dropsies, or anything like that. I am a goober and wear my flashlight on a NiteIze stretchy belt holster. I use my flashlight daily and usually charge the battery when the "High" and "Turbo" setting are hard to tell apart.

I did get the Fenix remote switch for my TK-12 when I had that on one of my ARs, and it worked fine, but I am not tacticool enough, so I took it off. I did not think it took a lot of force to activate, but I just didn't think it needed to be on my AR, so now it sits somewhere in my bedroom, quietly pondering its short span of usefulness.

Not wireless, but doesn't require a wire back to the furnace. I have been using something like this for over a year now:

It senses pressure in the duct from the furnace blower and kicks the switch on. It needs to be hardwired to interrupt the power to the outlet the fan is connected to.

I ran into one strange issue. My ducts are in unconditioned space in the attic. One day, I left a single window open on the main floor of the house and the wind was blowing directly at the window. The wind increased the pressure in the house enough to pressurize the ducts and kick the fan on a few times. Otherwise, it works really well.

To make it clear, this pressure switch is on Neutral for all inline blowers for the three zones. Purpose is - if the HVAC is not blowing air, don't run in-ines.
Hot wires for each zone are managed by Z-wave switches, that only turn on, if the zone needs to meet certain heating or cooling temp.

Problem I have is that in heating mode stage 1, whole system does not have enough pressure in ducts to set off the pressure switch.

From everything I read here, looks my options might be limited to adjustable switch like https://smile.amazon.com/Dwyer-Adjustable-Differential-Pressure-Connection/dp/B00ATGAPD2

What I realized is that if I use one of the RIB relays, in-line blower will start pushing air the moment furnace or compressor turn on but the HVAC blower has not turned on yet. That would lead to unconditioned air to start blowing.
