👍 One of check-marks for a good HVAC video is if I can play it at 2x speed and catch it all. With this one, I play it at 0.5x speed, i.e. "real slow". This is because I have to look at the Danfoss screen and have my eyes and brain MEMORIZE the screen. The experienced pros already have the screens memorized, so they go zip-zip-zip through the screens and leave us newbies confused. Going fast through controller screen is ok -- IF -- you can play it at 0.5x speed and learn/recite/memorize the screens. This video does that. I haven't even made it all the way through at 0.5x speed, but I know I'm learning/memorizing when I play it at that speed (there's a lot to memorize on these things). 👌
Hello Gendron, I'm struggling with this video. I'm playing it over (and over) at .5x and .75x speed. (Most of the rest of you vids I play at 2x speed -- sign of a good video if I can play at 2x). This is a good video too, but us viewer just don't have a "mental picture" of all the stuff going on inside a Controller. It's obvious you know it frontward and backward, but this newbie has a hard time keeping up. I play it slower so I can read the Danfoss screen on every scene. (And that Point and Location material -- phew; that makes the 'standard thermostat cable' look like kindergarten. .... Time for another slow play. Thanks for making.
I have a problem, in the "auto/manual relay" screen, the compressors have a status of "Remote", and it does not allow me to modify them, why is this? I need help.
Something like that might mean that the compressor is ran off of something other than that controller. But the system is monitored by the controller. I could not tell without being there but that's what I would look into. For example, a compressor might be run by its own controller.Or a thermostat to a particular box. What the temp probe is tied back into the danfoss fast system Hope that helps
Min 0:54 What is the "37.2" under the 18.9 Actual psi? Also: isn't -23.7 degrees F bleeping cold? Are there really reach-ins that are THAT cold? If so, what are they storing in there? * * * Does this Suction Group "have a problem"?
18.9 is Is the actual pressure 37.4 It seems to be the actual temperature. And yes, most reach in frozen food The suction group will target around - 22 to -23. The evaporator with be about -20. This will make a box temp of around -10. A good rule of thumb for low temp. If the box -10 10 under is the coil So the evaporator coil is -20. Then three under for the suction -23 And most frozen food is -10 box. Ice cream melts at 10 degrees. So most places keep it under 0 Hope that helps !
@@gendronhvac-r1269 Yes, yes and yes. Thanks. *** Hmmm ... then if the target is -23, and the actual is 37... I sure hope that case isn't full of ice cream. Oy... *** Great factoid: ice cream melts at 10F. Have to remember that next time I go to the deli.

Gendron the goat for making all these videos for us newer techs
Thank-you for the kind words :)

thank you for your great educational videos.
you are doing great.
great work with your explanation diagrams.
good bless you 🙂✅
I haven’t seen any new videos in a while, hope all is ok.
I’m a fan and I watch and learn all the time I watch
I'm glad they help :)
And I Got a new job so I can not post as often but I have some stuff comming :)
Can u please make a video on how to add oil to the rack system. Thanks. Excellent video and i am learning a lot.
Good deal, i usually only deal with e2 so this is great
Thanks!
I needed a 'crash course' in controller reading, and this is it.
Will make multiple play-stop-reads on this one.
Thank you so much
It would be great to see a video on case temps vs supply air temps / evap temp expected temp differential
Sure I can try to make one at one point :)

You can also press MENU instead of ESCAPE to go to the lower tab settings
Thanks for the comment. I I didn't know that. :)
Bro electrical fault finding vids please 😌
I will try and post something:)
could you go over store leak detection systems?
I can try too !! :)

Does this Suction Group "have a problem"?

The evaporator with be about -20.

A good rule of thumb for low temp.
If the box -10
10 under is the coil
So the evaporator coil is -20.
Then three under for the suction
-23
And most frozen food is -10 box.
Ice cream melts at 10 degrees.
So most places keep it under 0
Hope that helps !
