Chris, you have to enter the tonnage for each stage, not the total of the unit. Multi-circuit is correct for multiple compressors, multi stage is if you have variable capacity in the same compressor. On that unit the compressors are identical so 50/100%. 3.75 isn't an option so set one to 4 tons and the second to 3.5 tons so the "Total Active Tonnage" says 7.5 tons. You had it set up as 7.5+7.5 and it said the total was 15 tons, that's why the airflow was messed up.

I love Otterbox defender cases. It has one for S8 but not for Ultra.

CHRIS. Haven’t watched to the end yet, but multi-stage is for refrigeration circuits with multiple stages of compression. For instance - two compressors in tandem as on larger Trane Voyagers and Intellipaks. You would use one set of probes for these two stages because you are making measurements at the same ports, just staging compressors on and off. Multi-circuit mode is for systems with multiple discreet refrigerant circuits. Like in a Lennox RTU with 3 compressors sitting side by side, all with their own piping and metering devices. Hope this helps. Also, there used to be a bug in multi-circuit mode where you would select the number of circuits but then you had to select the number again in the System Info page. I believe they have fixed that but I saw you work through that in a previous video.

Could also be the compressors with the solenoids built in for staging

I like the call on insulating the discharge line. It's always amazing how temperamental txv bulbs can be.

Muti stage= 2 stage compressor or tandem compressors. The other option is for multiple compressors with their own circuits that are separated. Those predators have their own condenser coils for each stage. It's the same as Lennox does. The only commonality is the evap is split top to bottom for Y1 and Y2.

I learned the importance of condenser fans yesterday. The repair people said a wire somehow got broke which powered the fans, so the store I work at apparently came VERY close to loosing almost all the refrigeration capacity for the whole store. Everything almost overheated. I can’t even imagine how expensive repairing that equipment would be since the compressors alone are taller than me. :/

Honestly, I have been getting into the habit of jumping to the end comments and then watching from the start so I can watch with your words fresh in my head to reinforce the lesson. Has been helping me big time.

Extremely enjoy watching your videos . Extremely Thorough and unfortunately that’s rare these days . Keep up the great work

Chris, thank you so much for the post! I'm not an HVAC tech, I'm a landscaper and a T shirt print operator, but I love to see your troubleshooting process. I definitely agree with your closing words in regards to technology being both a benefit, but also a curse if you're struggling to understand it. I remember a situation where I had a guy apply almost 2x as much fertilizer on a commercial property I used to care for because she didn't quite understand the scale when she was mixing the chemicals. No harm done really, but we both learned something that day. I've been interested in going into the HVACR field for a couple of years, but haven't made any decisions yet, but maybe in the next year or two, I'll get myself put together enough to start the process. Again, thanks for posting!

Went straight to airflow first and great hit!

Thank you for video, very informative as usuall. In my experience when those compressor's are so loud it's usually low on oil. I didn't see you checking it and I don't know is it possible to do it. So maybe I am wrong 🙂

When anything is even a little loud i like to wear foam ear plugs. After getting used to them, you can notice unusual noises just as well as not wearing them if your hearing isn't broken yet. Listening to music with ear plugs is a different matter of course.

Jesus, that cap trick is brilliant!

My company got called out to do a start up on one of the york units that had never been started after 8 years because of the suite not having power. I came and it was flat on both circuits. Found leaks on both txvs equalizer tubes, the coils, and the low pressure switch on circuit 1. Got york to warranty the coil after all this time. Once we put in the factory charge, the unit wouldn't start and the board was showing all kinds of impossible codes. Replaced board and works like a charm. The location for the service ports is horrible. And the fact that units even come from the factory without liquid service ports seems preposterous. The unit I worked on was a heat pump

Time for a call to Measure Quick tech support. Also suggest they offer courses on setting it up.

I agree....way to much information to input to get the readings. Much too convoluted for practical everyday use and time consuming. It is nice for start ups and for general use....but not the most user friendly for commercial type equipment. You have to profile each stage, circuit etc. Customers pay for you to be quick and precise.

Holy shit that tablet is huge!

Remind me to never use measure quick until it becomes easier and simpler to use. I'll be sticking to the measure slow method by using 2 separate measuring devices.

It's a great software it can just be a bit confusing at times, but I still plan on using it

Wouldn’t have thought that sensing bulb would have been the issue.

I noticed that unit had Bristol reciprocating compressors. Those things have always been loud. Like its about to throw a rod.

On residential, they sell variable speed compressors as multi-stage. I'm just a homeowner, so I don't know if they sell measure quick to residential service providers, but that may be a difference in terminology.

Use some heat-sink paste between the line bulbs.

The reason that the first circuit doesn’t use the full capacity of the unit is because if the unit was only on the first stage it wouldn’t be running at full rated output. I think you need to select the rated output of only the first stage and for stage 2 then you would select the full unit rated output because it assumes if you are running stage 2 then stage 1 would also be running.

I melted a probe. Still works though i learned my lesson about it

Chris, it looks like measurequick is acting as if a multi-circuit mode is looking for a VARIABLE SPEED BLOWER. That is why your airflow numbers are wonky when looking at first stage vs looking more in line on the second stage. When I tried this on a VFD controlled blower in a Carrier, it all made sense. Hope that helps!

@jasonjohnsonHVAC

You have to input or import information for each stage. By default the blower is on constant volume. I messed with it this morning and if you put the information for each stage into MQ it'll spit out the correct operating pressure, temp, airflow, electrical etc.

I'm no expert by any means, but that multi stage vs multi circuit thing makes me think of the new heat pump I put in last year. Its a single compressor but "multi speed" where the logic actually runs the compressor and fans at multiple speeds to simulate multiple separate stages and make it more efficient. But I agree they should make the wording more clear on exactly what to use for what equipment

Is that AC 2 the one with all the evap coil leaks ?!

A 15 ton two stage unit may have a 10 ton circuit (compressor) and a 5 ton circuit (compressor).

To adapt. That's been my policy from day one.

Personally, I would call multi stage a system there multiple compressors are "stacked on each" other and working together in one circuit. And multi circuit is for my understanding, that each compressor has its own circuit, like one with R290 and a other circuit with 404. That's how I get it in my head 😅

I have no idea about the product but surely Measurequick must run a training course either on line or locations around the country? You would do the course and then your technicians if you think it's worth the money?

in my experience you are just better off ignoring the multi circuit stuff. its way too flaky on both fieldpiece and testo. just treat them separatly. sidenote: keep the backup belts in ziplock bags. it keeps them fresh a lot better than just chucking them in.
