I need a circuit or pre-built module that can take a 0-10vdc linear analogue output to close a contact when it hits a hopefully adjustable voltage. Is there a cheap prebuilt module out there? I think i'm lacking the correct vocabulary to search one out. I've built some simple PCBs in the past, but it has been many years. I'm hoping to avoid having to relearn all the basics of electronics to design what I'm positive is a dead simple function

Actual usage if it helps. I have CO2 sensors that output that linear signal, and I need to open air dampers at a threshold. I'd love for the threshold to be adjustable, but can get by if its locked at around 7v. If the relay on a prebuilt board can't han

Everything happened as advertised. 'Bout all I have to say. I know it is hard to trust anything these days, so I figured I'd post this.

I have several HVAC compressors and fan motors i'd like to use for some projects. They range from 165vdc to 350ish. I have the boards that pushed them, but don't have the EE knowledge to modify or simplify to make analogue inputs. I've looked around for generic drivers, but am not really finding anything in that range.

Is there a <$200 of the shelf solution? Is there a very simple PWM schematic I could fumble my way through building? I don't necessarily need all the fine control they are capable of, although a simple speed control to fine tune them to my applications would be nice.

Assuming they are worth repurposing, even pointing me in the right direction would be great. I'm in one of

ARUF line

Gotta say, build quality is kinda on point. Better than some of the "good" brands' base line equipment. The evap coil is especially beastly and solid compared to many.

What is everyone going to do if the other big names keep getting more flimsy and the reflexive mocking of Goodman isn't justified anymore?

That being said, I'm just setting this one air handler due to an odd set of circumstances. I was just shocked at how solidly and tightly built it is compared to previous experiences.

I should probably know this, but I honestly don't deal with dehumidification in my area near as much as most of you. Our summers tend to be very hot and dry from july to sept.

The few stand alone (big) dehus ive messed with lately have the evap first, and cycle the compressor to keep from freezing up. These are pricey units, and I don't understand the engineering.

• why do they run evap pressures low enough to freeze so quickly?

• why don't they run some or all of the condenser air through the evap first?

Im staring at a psychrometric chart and can't see what i'm missing.

Clarification: I think placebo controlled drug trials are fundamentally immoral. I accept they may be necessary (sometimes, most of the time?), but wonder if they deserve the default acceptance they seem to have. I'm using "morality" instead of "ethical" because I want to avoid the immediate dismissal of my position by those who would just point out the trial applicant signs a piece of paper accepting the possibility of being in a control group. My objection has more of a ethics connotation than moral, but moral gives me more leeway.

Why do we put up with this? These asinine waits and requirements to get manufacturer support are clearly telling us the companies don't give a fuck about anything after the sale. Because of this, I will never sell another Daikin. I've done the same with other brands we've handled. Is everyone else accepting it as "just the way things be"????
