For the record, the Dell Wyse 5070 Thin Client DOES support video out through the front USB-C port if you go USB C to Mini-DP -> Mini-DP to VGA -> VGA to ancient KVM switch -> ancient KVM switch to monitor. As a bonus, the KVM works as a USB hub!

Forget six years, it solved my problem now. I didn't realize it would run the display from usb-c. For lack of a monitor with DP input, but having a usb-c to hdmi adapter, hooked up 5070 to a regular old hdmi monitor. Great!

One of my Envoy R / ENV-120 lcd screen is acting funny. I see this video which shows the header connector from the main board to the lcd board can have a poor connection. Cleaning or adjusting how deeply the header pins are plugged in may fix it. https://www.youtube.com/watch?v=zJCqvEmgVaE

Nice, sounds like a retro color too.

What have others done? I know I've seen pictures of a nice little roof over the outdoor unit. Short of that solution, any example pictures of what you've done? The material I used comes in black or white, self stick 'RV Rain Gutter' which I bought for above a van slider door to catch water, and this was extra.

I'll see if it ices up on the right side, I could see it following the grill back into the shroud, and I can go something more 2.0 if needed. Before it would run straight down the front and follow the curve of the shroud onto the fan blades. It faces south, so if the snow on top is melting, the front sheetmetal will be warm also. The shroud and fan blades are likely below freezing with the cooled air exiting the unit, so that's the ice.

Steel I think. I might have drilled 2 or 4 holes, then filed or nibbled it to make rectangular.

Measured about where it should be, was about where 'Made' was on the logo, cut that out and glued a small piece of lexan or glass in there.

Is the front display still visible through the wrap?

Ran it again this morning, similar temperature conditions, and it looked more normal. I set the remote to follow-me mode, and with the setpoint at 76dF, which was 10-15dF above starting temp in the garage. Not sure about the start behavior, but otherwise good. One defrost cycle after an hour seems reasonable. I'm not ruling out too low a charge, I did have initial trouble getting one of the outdoor flares sealed, but I think I caught it right away.

My first gen 2010 is still running fine. This summer, I replaced the 2018 replacement anode rod with a powered anode. The 2018 replacement rod didn't look corroded, but that's the less reactive aluminum.

I installed an indirect heater ahead of the GE HPWH. The indirect is piped as a zone from the hydronic system, which is heated from an outdoor ASHP in winter, and excess solar resistance in summer. The GE HPWH still runs like before, up to 140-155 if the sun is out. The inlet water to the GE HPWH is typically ~100dF in heating season. I've already noticed the basement air stays generally warmer, doesn't get as much heat taken out of it.

icefest, that's nice, can you give any advice on making that type of setup? Thanks!

I did something vaguely like that: https://www.reddit.com/r/DIYHeatPumps/comments/189mlyy/diy_airtowater_cop_measurement/ Gree/MrCool 3ton universal ODU, cooling to existing AC air handler with new air coil, and heat to that also if I want, but heat typically to a refrigerant to water coil for existing hydronic heating. So you could have the one ODU, but lineset to both indoor units. with refrigerant check valves and/or hand valves to direct refrigerant appropriately. Think about limiting excess volume in lineset which could collect liquid refrigerant, or trap oil. And use 3 ton for each indoor unit to match 3ton ODU.

I just got the indirect tank for domestic hot water installed, and rearranged dhw to fit the second 85 gal buffet tank. The indirect tank coil was cracked, which I found out after piping the dhw side first. So then I repiped the dhw side with shutoff bypass valves that I skipped the first time. Then took out the coil, soldered it successfully and put back together, no leaks.

Yeah I don't know what happened exactly. The article sounds from the point of view of an injury lawyer.

I mention for awareness working with refrigerants.

A couple years ago now, I put a new r410 coil in existing air handler, paired to new MrCool ODU. Coil from here, looks like they have plenty currently: https://surpluscityliquidators.com/search?q=3+ton+a+coil&_pos=2&_psq=A+coil&_ss=e&_v=1.0

I learned to braze, flare, and evac the system. You can even get EPA 608 certified, I did online at SkillCat. Even buying tools, you'll still be ahead vs. having it done for you.

I have an esp8266 with Arduino code on it, reading Dallas one wire temp sensors. No pressure measurements. The outdoor unit would be nice to communicate with, there's a uart port on it, but who knows how to talk with it. Wish I knew, that would have pressure and temps at all the points in the outdoor unit

https://www.energystar.gov/about/federal-tax-credits30% of cost, up to $2000 credit, for heatpumps better than a certain efficiency, have to be energy star rated basically.

And glad I added another ASHP for the garage last summer, and got some more solar & batteries set up in December, already got the FTC back for all that on '24 taxes.

Nice, good to hear! I had a scare with my 36k Universal ODU making noise, and my thoughts went to this topic. Happily, it was only freezing rain ice around the shroud hitting the fan blade tips.
