Great explanation. I just beganrefrigeration basic training (school) this week and this video single-handedly made The function of a D Frost Timer💯🙏🏾🙏🏾🙏🏾
30 years in the trade. I do hvac 99 percent of the time but do get thrown into Refrigeration. Never knew how these clocks really worked. Yes this was great. Why don't they teach this in hvac school. We spent an entire semester going over psychrometrics of air flow. Never once used a psychrometrics chart. HVAC school is a complete waste of time. Spend a year watching hvac utube videos 8 hours a day and you will know more than 99 percent of any hvac tech out there. I just wish we hade utube and the internet when I started 30 years ago. Maybe I would still have my hair
Charles,...SUPER video! would love to see the 'in action' video but also would love to see the next step on how the 'Fan Delay' happens. Great job and exactly what I was looking for!
much easier to understand, thank you very much, hopefuly you can do a explanation on a whole freezer or cooler wiring , like contactor, relay,capacitor,compressor,compressor heater, condensor fan etc.
Very nice .all the guys are on u tube talking my meter,my high pressure switch, there is my what the hell ever and then they say this is normaly open ohhh my bad normaly open and so on. but this is knowing video no confusion . very nice thanks
I just want to give you a internet hug /(-_-)\.... Seriously I've been in school 9 months and haven't had the slightest clue understanding this. Thanks to your videos I get it.
Hi, can you do a video explaining how condensing units are connected to case lineups (example, 36 feet of produce, or three 12 ft cases) ? Are the thermostats in all 3 cases connected in parallel with each other, and in series with the liquid line solenoid coil? Thanks.
I thing connecting and disconnecting the compressor with NO contact, thermostat is inserted to compresor, otherwise following your wiring plan we have a short circuit. "X" is the one contact of the "motor timer" next contact is the "N".
+kidd sheppard Usually in freezer application it will utilize temp termination. Time termination is your back up, which is simply the duration time set on your middle dial.
please use the word Neutral instead L2, because L2 in UK is associated with 3phase power supply and can be confusing for some technichans has just starting HVAC works
