Hi, Pay, TB here. They have a combo humidity and temp sensor that accepts all of the wires. It's a 21W06. In fact, I bet your humidity senor could be one of those, and the contractor mounted an extra sensor for temp because he didn't know. This is a good find. NAS keeps me busy with follow-ups to their installs... just like that one. I have a repair being approved for a pet grooming salon, where the M3 controller is keeping that reheat valve energized during cooling. When the cooling call overrides the dehum mode, that valve is supposed to drop out. I found it a week ago, and it had been that way for three years. I will post about it on HVAC-Talk when it's done.
nice video and good work. I troubleshoot for experienced electricians that are wire pullers in commercial, it is amazing they cant troubleshoot there own work.
Yeah I don't make nearly the amount of videos that I could. When I get a chance to let a unit cycle or something I will film. Sometimes explaining the unit operation in a video will get me thinking and that helps keep me sharp. So it's training for me as well. LOL
@@hackfreehvac Glad to hear it's helpful for you... Random note... I was on top of a parking garage in Dallas looking down at an apartment building (5 stories roughly) and saw no less than 80 turds on the roof, thought of you!
Great video! Lennox RTU`s can be a little overwhelming sometimes, I'm still not real comfortable with some of them. But if you read the literature that really, really helps! Can't say it enough, READ THE INSTRUCTION! BEST advice I ever got. lol
Nice find.. a good tool to help find issues like this fast with incorrectly landed sensors is a toner. Got one from lowes I believe. Just leave it hooked up on wire and go through all wires coming up to roof. It will start flashing and beeping when you get close to correct wire.
Yeah I don't know why I've never bought a toner. I've used them in the past for ethernet wiring and the such. But not so much on HVAC. Once I got access into the space below it didn't take too long to figure it out. I just needed to see what was feeding that voltage range. Once I saw the CO2 was normal I realized it was probably wired to the Humidity sensor and indeed it was. A lot of the wires are in conduit and in the wall with metal j-boxes behind each separate stat and sensor so the toner wouldn't have helped here.
Not saying you have to have.. I have one and rarely use it. Used it more at last company with cpc input boards and multiple cases. Mostly use meter now to confirm wires but it's nice to have when needed. Saves multiple trips up and down ladders for sure.
9 years = 41/hr but I literally have stayed up all day and night for the first 6 years learning and building Refrigeration and troubleshooting boards...your right man! Love your channel dude
Caught a similar fault on one of our dishwashers for a large hospital; Wire harness was mislabeled from the factory essentially leaving one of the fill valves disconnected.
Those HVAC guys that work with Ammonia systems make about that much per hour or more. Those units use 50 to 350 HP motors or even higher, and they are rotary screw compressors. Frick is the big name in that industry.
Safe to say that unit was not originally commissioned. At a minimum it looks they they did not even do a point-to-point checkout to make sure all inputs and outputs were terminated correctly on both ends. I wonder how long it has been operating that way. Nice find and fix.
Arizona, which has high demand and all, doesn't pay too high here. But cost of living is good. Pay is like 23 to 33 range generally with some higher 30's in some niche areas.
The prodigy is a nice high end product. I've been loving my last 5 years in commercial industrial. Residential just wasn't for me , couldn't stand the whiny ass customers.
As long as they feel cool air blowing, it is good. LOL I go to jobs all the time that had "Test and balance" by a separate vendor after start up and I can see that there is no way the economizers or fresh air dampers were possibly adjusted at all!
And in this example, you wouldn't notice the problem until it gets humid. We have a few weeks at a time where the humidity is above 20% so most of the time that IAQ input was not being affected much by being wired to the Humidity sensor.
Ive been doing resi for around ten years and its true, commercial units can be an entirely different animal.
That lennox is a very nice machine.

Always awesome videos. Learning lots about HVAC stuff from someone who knows what's up. I imagine it's not easy to film on the job, but keep it up!

Hell yeah 🤘 that was a good find right there. Excellent job 🏆
Nice little RTU. Lots of things to break down lol. Good troubleshooting.
Dame those prodigy control are nice

HVAC/R DUDE and I’m watching your shows and reaping all the benefits for free. Thank you Sir

Been that way since 2011 install I'm sure
Nice video !!
do you have more info on Lennox bacnet controls?
Union in Bay Area ,CA over 60$ an hour now on the check now.
Dave, I'll bet most of that money only pauses in the bank for a moment, before it leaves to pay for the exorbitant cost of living there. Am I right?
Art Houston there’s no way the young people could buy a house here. Rooms rent for 1200$ just a room.
Nor-Cal Refrigeration & H.V.A.C that’s insane
@@NorCal-refrigeration dude...I tried that once .was guy be like 52/hr...and the lowest 1bedroom apartment was 3200$ in distance...it's crazy as fuck
Yeah it is like California is it's own socialist country.
Isn't gasoline like over $4 bucks a gallon?
It is like $2.79 here now
Nice Catch !
Nice call on that trbl sht. Some times it's the most simple thing that eludes you
Great video! What would your guess be for hourly pay here in phx for a commercial tech with 9 yrs?
Arizona, which has high demand and all, doesn't pay too high here. But cost of living is good.
Pay is like 23 to 33 range generally with some higher 30's in some niche areas.
Make more videos of poking fun at Goodman turds, your commentary/rants are funny as frig
Yeah I've been slacking on the vids lately
So if you want to use this RTU as standalone is there a thermostat that has the humidity and CO2 sensor lets say "all in one"
Yeah there are thermostats with both. There will be the normal 24VAC outputs for fan heat and cool and then a 2-10/4-20mA analog signal for CO2
The prodigy is a nice high end product. I've been loving my last 5 years in commercial industrial. Residential just wasn't for me , couldn't stand the whiny ass customers.
I guess they didn’t check their work after the install.
As long as they feel cool air blowing, it is good. LOL

If I had your brain.
