[@vtheofilis]

Greetings from Greece, Chris. We use a somewhat different approach in my company for walk in defrost control. The kind of controllers that we use are most of the time the kind with two temperature probes, one for space temperature, and one for coil temperature. We programm a number x for defrosts per day, for y minutes, up to z degrees in coil temperature. I think it's simpler, yet not much less energy efficient, and you don't have to install the controller inside the walk in, but only the probes.

[@SedatedByLife]

You probably need screen on both ends of that rack as well. While they had a beam under it there was still a gap that they may be able to get thru. Nice choice though of material. Hopefully it is large enough mesh size to not get clogged up with fibers off of trees like cottonwood.

[@mrbyamile6973]

I used to work in Everett Washington, Seagulls loved nesting on the roofs. I was not allowed to mess with them. They are *very* protective of there eggs and young. The Seagulls dive bomb you, yes they actual fly around then swoop down flapping wings at your head and then they deliberately poop as they dive down at you. I had to use old filters to shield myself like Captain America when working on the roofs during nesting season :)

[@Georges3DPrinters]

10:03 I see right there that you can adjust the PID Loop temperature offsets, you ever mess with those? Me being a 3D printer person and having double some programming more familiar to me to deal with something like that for calibration reasons

[@Georges3DPrinters]

10:22 kind of cool that you can even adjust the microstepping of the servo motor that is attached to the electronic expansion valve. Microstepping basically takes the position of one of the steps that the motor takes and cuts that up into smaller steps using pulse-width modulation. 360 degree Revolution is 200 steps which works out to 1.8 degrees per step. And when you microstep you take those 200 steps and cut them up even smaller for my 3D printer is set to 16 microsteps, than that means there's 3200 steps per one single Revolution. Got to love stepper Motors and their ability to minutely adjust of valve.

The closing words gives a lot of knowledge for techs....

[@roetemeteor]

For future reference, you can clean off bird boo-doo with the following mixture. 1 part Palmolive 1 part Baking soda 5 parts water This is a pre-soak. If the mess is REALLY bad and smells HORRIBLE, replace the water with 3% hydrogen Peroxide. This *shouldn't* damage anything, but it will shred apart any organic waste material and dead things you come across with shocking efficiency. The significant acts as a de greaser. It IS important if you use this, you hit it with a specialized rinse before applying the wash. 2 parts Palmolive 1 part Lysol Concentrate 5 parts Water This is the actual wash. The pre-soak cleans very well, but is mainly meant to cut off major gunk, and this actually cleans what's underneathe it. The lyson disinfects. Rinse with water. Your coil cleaner does the job, but this stuff will handle virtually any organic material you throw at it. Shit, this will actually eliminate Skunk spray.

I have an interesting question, if you plan on putting a sprayer on a condenser like that would it be beneficial to put a whole house water filter housing and filter at the spicket to help reduce the calcium they are rather inexpensive at $20 and they don’t destroy water flow. I put one on my pressure washer and it works beautifully

I understand this is an older video! But I’m home with a broken ankle and watching a lot of old vid’s. Doing this shit for 40 years now. I have to admit, I can see the newer technology on larger tonnage RTU’s maybe 20 ton up, but the smaller equipment is a financial disaster for the equipment owner at breakdown. Like in your video, maybe it’s a 15 ton Trane with that ECM condenser fan motor failure. The driver fails and that it. Like this one, Trane had 0 in stock! Warranty system in a medical building, summer time, with the space at 80 degrees. Picked up a standard 1075 460v motor with capacitor and had it operating in 2 hours. Took a month for the factory to get me a replacement! Left the temporary motor in the unit since there are 6 others on the same roof. So much for simplicity! Great video’s
