The company I work for is a lennox dealer and yes those thermostats are not good. They do funky stuff, our company has been replacing any we installed for free that we run into issues with. Replace with a vision pro 8000 and be done

Man, We didn't get to hear you talk to yourself during the programming of the thermostat, Damn, Talk to your buddy Rick about a combustion analyzer, he's got a nice one, An Inficon, it looks pretty sweet, or try an Fieldpiece those two seem the best bet, nothing wrong with Testo, but those other meters seem a better quality. Good job Chris.

I was thrown by the "Honeywell Home" thermostat, but it's all about name recognition. Just like in data center land, Liebert was bought by Emerson, and Emerson Network Power is now Vertiv. I didn't know that last part, and it gets confusing when you start stacking brand names.

I just reprogrammed a stat like that to know that it has electric backup just yesterday. Not sure it really needed to be replaced but I'm also pretty sure its made for residential use not commercial so its fair to put on a commercial stat.

Great work. Thank you. I, personally, don’t own an analyzer because it’s VERY expensive, but it would help to know more info about the operation of the unit. What we do is getting the unit though.

I LOVE my tpi dc710. Blutooth and connects to phone with pretty good range. They make a manometer that can connect wirelessly to it so you can read and set pressures at same time. Has a water trap incase you are working on condensing stuff. Battery lasts quite a while. When you get the numbers you can generate a report which grabs the gps location and lets you add a job number and title to each report generated. Also has a temp probe built into it, one that measures exhaust temp and one that measures ambient temp. The app also does gas size calculating and stuff if ur into that

9:58 - I purchased the Sauermann Si CA 130 through Truetech Tools specifically for gas pack RTUs. I chose the CA 130 model over the CA 030 only because of the field replaceable sensor (even though they are rated for five years). Other than not having to send the unit back to the factory for calibration (as is the case with the CA 030) and the touch screen interface, both have similar functionality and both work with MeasureQuick. I was able to catch a faulty heat exchanger with this analyzer even before removing the panels (the tubing did have rust holes in the bottom of the bends and needs to be replaced). With the optional thermal printer I was able to document the analysis straight from the analyzer. I highly recommend this device for you. It is quite easy to use and understand even outside of MeasureQuick.

Thanks for another helpful and informative video, Chris. If no one it touching that thermostat then the issues suggest the internal memory has problems with 'bit rot' where, because of the way such memory works, the memory cells change state over time. Often, re-writing the cells will restore normal operation at least for a while. It suggests either very poor quality or very old electronics in that thermostat or poor manufacturing quality control. The thermostat problem reminds me of years ago with memory cards for a digital camera, some of which just became corrupted over time. Fortunately, they were fairly straightforward for me to recover. This is the main reason why I never leave any data on a Flash Drive (thumb drive) or Memory Card that I don't have a safe and secure copy somewhere else. I know you use USB Flash Drives for firmware updates on machines. One of the best things you can do is learn how to refresh, backup and ideally take a Disk Image of flash memory storage media. Even manufacturer-supplied drives can go bad, and having the skills I just mentioned could save you from, worst case, a bad firmware update that trashes the machine in some way because the controller didn't recognise the firmware was actually bad or simply not being able to apply a needed update to get a machine working in a particular situation. On a more personal level, it could help you recover videos and photos from your own phone(s) and camera(s).

@marster37 9 ай бұрын

Chris, on those lennox economizers the wire leading to the enthapy sensor that has the corrosion on it is always the + wire and truthfully you can just snip off the corrosion part and snip the wire on the other side of the quick connect and run that wire through the already factory predrilled hole that will be next to the quick connect plug. Wire it up and that enthalpy sensor will work but I personally like using the oda sensor that's hooked up in the condenser because I'm able to use the magical temp number of 50 degrees to start ecomizing. Even if it's pouring down raining with 100% humidity in the air the 50 degree air is the perfect point for ecomization. You have to made a few letter settings under id number one and change the second letter to a t

@brettbuck7362 10 ай бұрын

I have no specific information about these controller circuits, but those sorts of low-level logic circuits are always prone to occasional state changes like the one you see. Electrostatic discharge is one good way this can happen, for instance. Computers have to deal with this all the time, they have what is called "error correction" that can detect bit flips like this one and fix them.

@raminit1 10 ай бұрын

As a resi tech I’m not sure of what the challenges are for combustion analysis for commercial. But the Bacharach Insight Plus has been my go to. With field replaceable O2 and CO sensors it keeps your down time low. I do recommend the NCI combustion training for application though. They touched on commercial when I took it but it definitely wasn’t focused on. I remember Jim Davis did talk about CO build up on roofs that are fully surrounded. So that could lead to poor combustion air and for restaurants, poor MUA.

When commissioning a system I don’t set it exact to 1.6/3.5. The data tags will have a low fire/ high fire temp rise setting. I always adjust my GP based off my temp rise. If the temp rise says 15-45° of a rise I shoot for generally 25° rise. Try to keep it on the low end so it’ll slowly Evenly heat everything in the space so there’s no hot spots or cold spots throughout the space.

Great stuff Chris. Had a remote stay temp readout for an EMS controlled customer that the temp readout would go up when the temp would go down inside the store. Checked zone sensor in the store and the ohm/temp reading was in line. It was very weird.

@jasonjohnsonHVAC 10 ай бұрын

Somebody could have put the wrong thermistor in it. There is a difference between PTC and NTC. Mainly which direction the resistance goes. PTC is positive temperature coefficient and NTC is negative. NTC the resistance goes down as the temp goes up.

Thinking of buying a combustion analyzer (fieldpiece expensive one) for our shop for the rare instance when we need it.

Combustion analyzer isn’t really going to do much for you on your standard package unit. Derate system for altitude (orifices and pressure switches), adjust gas pressure to manufacturer spec, check temp rise and airflows, make minor adjustments. Save the Combustion analysis for High efficiency equipment that requires it.
