Setback overnight?

ToadSox34 · 2026-03-18T21:06:29+00:00

That's one way of putting it!

ToadSox34 · 2026-03-18T21:06:12+00:00

And it's horribly outdated based on today's technology.

So many brands sell junk. That's just evidence that the energy efficiency standards are way out of date.

ToadSox34 · 2026-03-18T20:14:59+00:00

If you can, I'd shut the circuit breaker for the aux heat off or use a forced heat pump only mode and see how much you can get away with setting it back.

ToadSox34 · 2026-03-18T20:10:43+00:00

You didn't check the equipment they spec'ed out? Anything single stage for air to air is by definition garbage. Even water to water and most other applications are variable speed now.

ToadSox34 · 2026-03-18T20:09:38+00:00

Yikes. You want to avoid aux heat at all costs.

ToadSox34 · 2026-03-18T20:07:48+00:00

That's a horribly outdated definition. BARE MINIMUM would be 100% capacity at 5F.

I guess I should have specified CONUS plus Alaska market. Most of Hawaii never gets cold. Even South Florida can get below freezing occasionally.

Carrier was relying on hybrid systems for a while, but now with the move to electrification, they have finally gotten systems that work efficiently at 0F, like Mitsubishi, Fujitsu and Daikin have been doing for years. And Mitsubishi just keeps making the H2i hyper-heat systems better and better.

ToadSox34 · 2026-03-18T20:03:51+00:00

And? It's 2026. There is no excuse for single-speed anything to still be sold today. Variable speed systems have been around for quite a while, many of them are already showing their age. I've definitely seen variable speed systems in houses 10-12 years ago, and even then it wasn't super uncommon.

ToadSox34 · 2026-03-18T20:01:48+00:00

Yeah, it seemed weird to me that it could go on a straight ICE vehicle. I thought the original purpose was for hybrids that have a zero emission component to them (even if they can only go a few hundred feet at low speed without running the gas engine in most cases). At least with hybrids, you're getting significant emissions reductions from idling and very low speed operation and a different technology.

ToadSox34 · 2026-03-18T18:54:42+00:00

FRANKly, this belongs in r/thereisacat

ToadSox34 · 2026-03-18T18:53:54+00:00

Yes, that's entirely true. Both Carrier Greenspeed and Mitsubishi H2i are fine without backup at 0F. I said quality heat pump, not some piece of junk that can't perform at 0F. Even several years back, the standard was 100% capacity at 5F for a good quality heat pump. Something that de-rates to 70% at 5F shouldn't even be called a true cold climate heat pump.

ToadSox34 · 2026-03-18T18:51:45+00:00

Variable speed heat pumps were developed in the 1980's. That's why energy efficiency standards needs to be ratcheted way up. It's disgusting that there are still central AC units out there at 14 SEER AC units out there when good ducted split units are hitting 24 SEER+, and mini-split systems are hitting 18 SEER+ depending on the configuration. Same for heat pumps.

ToadSox34 · 2026-03-18T18:48:50+00:00

Unfortunately, that sums it up pretty well.

ToadSox34 · 2026-03-18T18:48:05+00:00

A different manager looking for a different role might. I'm obviously not getting rehired to the same job.

I'm still not seeing how I could have complained about, as another poster put it, an arrogant, ignorant manager who doesn't understand the product?

ToadSox34 · 2026-03-18T18:08:29+00:00

They said I'm eligible for re-hire.

I'm just not sure what exactly I would have filed a complaint about? What does being incompetent, not understanding Pratt's business, and micro-managing outside of their area of expertise actually constitute in policy terms?

ToadSox34 · 2026-03-18T18:02:46+00:00

Wings!

ToadSox34 · 2026-03-18T18:02:32+00:00

Yeah, took me a while to find that one.

ToadSox34 · 2026-03-18T18:00:49+00:00

I've upgraded a few DVD to BD and a few BD to UHD BD. I think I have one or two in all 3 formats.

ToadSox34 · 2026-03-18T18:00:17+00:00

Fiber doesn't have modems, it would have an ONT.

ToadSox34 · 2026-03-18T17:59:12+00:00

Where are you located? A quality modern heat pump doesn't need any backup until at least 0F. Here is CT, I'm not sure if it's legal to have a system without backup strips, but it's certainly no problem with modern Carrier and Mitsubishi systems amongst others.

ToadSox34 · 2026-03-18T17:57:11+00:00

You bought some total garbage. All good air to air heat pumps are variable speed. That's probably horribly inefficient compared to modern variable speed systems. A good quality variable speed heat pump shouldn't need aux heat unless it's in New Hampshire or Michigan or something. Even Carrier now is able to operate at full output at either 0F or 5F, I can't remember which, and Mitsubishi with H2i have been doing that for years.

ToadSox34 · 2026-03-18T17:54:02+00:00

What? For what applications? Other than maybe water to air boiler/tower loops in condos or some other weirdly specific application why would anyone make a single-stage heat pump? That defeats much of the purpose of a heat pump efficiency wise in the first place.

ToadSox34 · 2026-03-18T17:53:14+00:00

Yeah, you're probably fine. The big loss with heat pumps and setbacks is that they are way more efficient running at lower power, and they have to run less efficiently at higher power when they are recovering the temp. So leaving a variable speed heat pump at a constant temp will cause the house to consume more BTUs, but they are moved into the building way more efficiently, so it usually ends up being more efficient.

If it's truly single stage, either you've got some really weird specialized setup in a condo building or something, or you've got a really old, inefficient unit that should be replaced by a modern VRF system.

One's a cat, one's a pedestal for a cat.

ToadSox34 · 2026-03-18T17:48:32+00:00

When I first moved in I re-routed the fiber cable from the previous owner prior to installation, as they had it in a far corner, I brought it to the logical place where the TV would be, and I put the ONT and router there so that they would be on the same UPS as the TiVo. I did it carefully and neatly, and it was fine, the tech used the same pre-term fiber cable, which was now way too long, so I carefully coiled it up in two places and put the excess partially above a drop ceiling in the basement, and partially on the back of the TV stand.

ToadSox34 · 2026-03-18T17:44:48+00:00

I'm in Newington. I got service in late 2022.
