Oh it sounded like they were cooling some generator or something. AC fan speed is easy to control.. DC isn't hard if it's PWM

 

HVAC guys, can overcharging your system make it not cool as well?
ie: topping off the truck when it's actually got the recommended mass of refrigerant already in it?

 

It can reduce performance yes. If it’s enough, it can cause the pressure relief pop off too

 

Yeah its not good for the system and effects longevity and performance of the system

Damn. We just missed the Black Bear Pass mudslides.

Mudslides strand 15 people and eight vehicles near Telluride

Yeah it kills performance, charging in extreme heat is hard I've found, same with cold haha. Auto systems take so little it is hard to balance, I like to charge at the nearest to 75* part of the day, easiest to hit the bullseye on low pressure side specs

when you fill the void, the void fills you

Or something like that

 

Making baked beans from scratch today, for the first time ever. Ought to be interesting…

 

I read this as just 'making beans' from scratch and was confused

 

The cats name was Scratch.

 

@Speedytech7

this wasn’t your district, I bet .

We are too poor for a district worth of POE PA systems and netowrked projectors.... we got VGA and a rack of amps and relays

any hacking will be from asbestos exposure while physically hooking up to any of it

 

Better than half assing a bunch of expensive shit.

Asbestos is less fun though.

 

Yeah there are buildings I refuse to work in other than the normal work spaces. But we know what we can make work without costing everyone too much money. I am pushing for more networked PA/Bells/Clock systems though, retrofitting is a pain but its easier to retrofit to POE devices than it is to keep hijacking the old two and four wire PA/Clock systems to try and make them work with modern controllers (we sunk money into that and it is a worthless stopgap)

 

Yeaaaah, those make work solutions are never great. Hard to talk admins into it if they’re not already in on it. We have some customers who bend over backwards to use their 50 year old underground cabling on the wayside, and then we have others who have no qualms about ripping out everything, trenching in new cable and dropping in brand new gear just so it’s the same as every other location. So much easier to deal with the second group, less weird problems.

 

Update: fire alarm works
