One year later what's the status on this project? Have you managed to lower the CO2 levels?

I've worked in data centers where monitoring systems on cooling are beyond anything... Maybe except for nuclear plants and a few other application. Anyhow, THIS channel is what I wish I had found before buying my AC unit earlier this year. NOW I am left with my own self patching a few wires here and there to tap into so home automation... You'd be an insanely good contributor to the "home assistant" community.

Great video, thanks for showing us how it works.

How many line clamps do it take to complete this procedure?

Really awesome video! Could you please do something like this for dual fuel (gas/heat pump) settings?

I really appreciate this video as I just bought a house with the Bosch 7739832068 heat pump and brought with me an ecobee premium from my previous home which had a typical gas furnace system. But I believe the install for the system might be incorrect because when I go through the wiring screen on the ecobee telling it which wires are hooked up, it tells me it’s an unusual setup. I’ve had 2 different HVAC people out including the company who installed the system a year ago before I bought the house. Neither place knew much about the ecobee and therefor weren’t much help in telling me if it was all setup right in the settings. What worries me most is that I feel like the wiring might be wrong. I only have Y, G, C, O/B, W2, and R. And the company who installed the system but not the ecobee that I brought with me wasn’t sure if the W Wire went to W1 or W2 so he put it on W2. But I also wonder if I shouldn’t have a Y2 wire. All I get is HEAT and AUX STAGE 1 HEAT. Shouldn’t there be more stages? I’d really love your insight on my system since the 2 local places I paid to come and look at it didn’t seem to know what they were doing very well. Can I contact you somehow? I could pay if need be to get your help.

Outdoor unit is supposed to be higher than 6” above floor

Great video. I guess it doesn’t matter the evap coil is bigger with a variable speed compressor because it can control the saturation temp. With a single stage compressor a larger evap coil isn’t good for latent capacity because the larger coil gives it a larger temp/pressure? Is this correct?

Thanks! A cliff hanger!

You made this video Jan of 2022, but do you remember if the compressor was a single stage, two stage, or an inverter? I am currently starting up a 24,000 btu comfort aire inverter heat pump. Vacuum below 500 microns broke the vacuum with about 4 oz of R410A, and have not added any additional refregerant. Just been running it and watching the numbers.. My approuch is 11 degrees..The seven segment display on the HP circuit board in charge mode shows high subcooling 56 degrees it calls for 36 degrees in heat mode. All the other numbers look ok. Furnace blower on high. There seems to be alot of control going on with a inverter heat pump. The delta T accross the indoor coil 16 to 20 degrees.

Hi Tim. I assume you are using Ecobee. I am asking because Ecobee can't handle inverter systems. Yes, Ecobee works with IDS 2.1 but I don't think you get the full benefit of the system.

Where is the video for heat? My bosch system is screaming like a banshee with a ecobee 3 lite and having the HVAC installers back to check again. Just not doing what I think it should be doing as a invertor heat pump. getting bewtween 10-20 min run times. Just changed heat differential to 1.5 degrees instead of 1. How are sensors utilized or do u not use them?

Just one question though I am sure you are talking about super heat at the evaporator coil right, not at the condenser coil

Bro you really are the man!!! Thank you for your videos! I was trying and on the rise on learning this stuff but I was not getting the full explanation, but I am understanding way more clear now. 🙏

Lol i bet!

This was a good one tim! Come work in the PNW and you’ll rarely even see it as low as .93

My Rheem system had a similar problem, and I did the same thing, lowering the fan speed, except I don't believe I have dips switch on my outside unit. The best thing here is i have the same thermostat, and your breakdown of the suggested setting is amazing.

By any chance you can cover these videos in SI units as well?

Thanks TIm, just started in building services (consultancy) and your videos are helpful! 6 months into the job and your videos are very practical and useful.

Great stuff! Another important video. I would’ve watched an hour on this topic.

What an awesome video, your explanation and setting worked perfectly for me. When will you make a video on setting for heat during the winter months? Thank you

Tim as always nice video again

@timdestasiohvac Thanks for the great videos! 7.57 Latent (equipment cap.) - 5.1 Latent (load calc)=2.47 Latent excess cap. in the equipment. 2.47 x 50%= 1.24 extra latent capacity to add to the sensible equipment cap. 25.3 equipment cap. + 1.24 Latent excess= 26.5 latent cap. for the equipment. 26.5 sensible (equipment cap/NEW) / 27.4 sensible (load calc)= The new equipment will satisfy 97% of the sensible requirement. I thought I learned somewhere that Manual J(load calculation) has a built-in overestimate? Maybe 10%? Is this correct? If there is an overage(safety factor) in the load calc., the 3% shortage probably won't even be noticed and in reality may not be present. The building heat load will be satisfied by the equipment and occupants will be very comfortable. Really enjoy all your content and building science videos! Thanks again.

Hey Tim, great info here! question for you though, with a home in need of 3 tons of cooling, would you recommend 3 ton condenser and ahu or upsize them then derate with j2 dipswitch?

Keep making videos!

Great video! I've been trying to figure out how to remotely monitor whether my oil boiler is tripped out on safety, but this doesn't seem to be a thing anyone has ever implemented?? Do you have any ideas? It trips once a week or so, but techs and service don't seem to be able to fix it. I can't find any issues myself either, but it's winter and I need to be able to monitor if it trips before the house goes cold.

Thanks!

Tim, are we going to have to wait until next Saturday to get the next part? You're driving me crazy brother... (Haha, Good things come to those who wait.)

You explained in less than seven minutes what my engineering lecturer could barely explain in two hours.

Thanks for another great video.

As always nice video I really like it

I have a two year old Si-ca 030 I sent is in for re calibration last year and paid the ridiculous $450 this year after sending it is was told it needed $670 of parts. This tool I sent them is in perfect and flawless condition. And they are trying to bully people into basically paying almost as much as a new tool every year. I don’t think I will use Sauerman any more unless they respond and change their business practices.

Thanks. Little late today! Usually watch this while eating lunch, lol. If I don’t see Psychrometric Saturday by noon I’m thinking I may need to send someone over your place for a wellness check! 😂 I think this series is great. Should be must see for all techs, and good for review.

Great Videos Tim!

These Bosch units don't hold up. Coil leaks, control board failures, blower motor failures, bent blower motor assemblies from the factory, etc. these units have very low capacity when compared to other systems. Would absolutely recommend that you stay far away from this Midea system, rebranded as a Bosch.

Another great video. Thanks.

Good stuff, as always, thanks, Tim!

Why does mine run all the time? It starts runs, stops for 1 min, kicks back on and repeats this all day. Very annoying

What does this have to do with psychometric?

Can you recommend any app instead of using paper charts.

Anyway to get this to alert you when temps drop or rise to a set temp? Been looking into walk in refrigeration monitoring.

Good stuff as always Tim. Thanks.

Would that work for 3 wire humidity or enthalpy sensors as well? How about expansion capabilities? That's really clever, great job and video!!

Great job. I appreciate this vid

I got the first generation Bosch. Has been amazing. Will I get more benefits out of the Ecobee than Bosch BC-100 ? I don’t have a 2 stage air handler.

Which Sonoff is this?

Tim i have a bosch. I need some tips with the HP. And balance point explained. The hp will run below balance point and sometimes itll run say point is 35 itll run at 28 then next cycle is fossil. Is this common?

As always Tim you are the top technician. No way to miss your videos
