Seven years ago, when I decided to take my training “on the road” sort of speak and go “national,” I was concerned how an old, broken-down HVAC contractor from New York…with an admittedly strange sense of humor, would be received outside of my home area.
The last seven years have done nothing but reinforce what was my already strong love and appreciation for this GREAT country of ours and the GREAT people of the United States.
I have now conducted HVACR training events in 41 states and I can say that in each state I have been warmly welcomed and ultimately accepted…in fact, I can say that I have friends in 41 states and that is a VERY special feeling…profound and special.
No matter where I go in this great country, I meet people who may look and sound different than me but all have similar needs, hopes and goals. Those who know me and have attended one of my training events know that I don’t avoid the tough subjects if they come up…politics, religion, history…and yes, even football.
What I have found without exception, is that people of different opinions and beliefs CAN converse when each has a respect for the other’s foundation…their background, their intelligence and their experiences. One guy from New York has a different foundation than a guy from Texas, or California, or Georgia…not a better foundation, just a different foundation.
Possibly the greatest joy of my job is how it allows me to meet people all around the country and simply talk with them…obviously my primary mission is to share my experiences within the HVACR world but that platform allows me to meet with, speak with…and so often, become friends with people who in turn share their experiences, beliefs and knowledge with me…and that is what makes my job so powerful in my life.
My platform has allowed me to share the story of the man I call my father, Elwood Weaver, who at the age of fifteen, so infuriated by the attack on Pearl Harbor, ran away from home to join the Marines and ultimately fight in the battle of Guadalcanal. I told Elwood’s story, as I do to virtually every group I’m in front of, in Hopkinsville, KY just this past December. At the end of the class a young man named Ty Heltsley came up to me to tell me how his grandfather was with Elwood in the First Marine Division at Guadalcanal…WOW!
Elwood passed away 17 years ago but in that moment when Ty and I were speaking, Elwood was right there…how powerful!
I would have never met Ty if not for my job. I would have never known about Ty’s grandfather if I didn’t share Elwood’s story.
One young man from Kentucky with seemingly nothing in common with an old guy from New York other than our chosen profession, because we spoke to each other, respected each other’s foundation, we discovered a bond that each of us going into that meeting room in Hopkinsville, KY could have never predicted.
As I say at the end of Elwood’s story when I tell it…that was America in 1945 and that is America in 2018!
God Bless America!
IT’S A GREE THING! The algorithm of the GREE inverter compressor feature for Compressor Discharge Protection was developed so as NOT to cause or allow repetitive, nuisance callbacks…this is music to the ears of HVAC business owners!
Let me explain…
I always say in my GREE Mini Split Troubleshooting class that when we have to go back repeatedly to Mrs. Gillacuddy’s house because of a repetitive error code, such as E4 COMPRESSOR EXHAUST, (DISCHARGE) HIGH TEMPERATURE PROTECTION…and we can’t charge Mrs Gillacuddy because this is an ongoing issue with no resolution in sight…well my friends, that’s is the devil’s work!
Repetitive, nuisance callbacks make the installing company’s profit evaporate and also makes them, and Mrs Gillacuddy lose faith and confidence in the product.
The title of this article is, “IT’S A GREE THING”…it’s also a man thing to not read the installation or service manual…and that’s a shame because there are so many hidden gems in the GREE product manuals…here is an example.
On page #13 of the service manual for the Multi21+ 18 & 24K systems, it states the following…
What the above is saying is…because this system utilizes an inverter compressor, the compressor can adjust it’s speed, (RPM) accordingly when the compressor discharge temperature is too low or too high, (too low, it speeds up / too high, it slows down).
The real gem here is the last sentence… “if the running time of the compressor is longer than 7 minutes, the protection record will be cleared.”
WOW! That is music to my ears and the ears of any installing contractor and / or service company!
What that sentence is saying is…after an initial E4 error, should the compressor then run for 7 minutes without another E4 error, the system has the ability to essentially say to itself… “well, we have run for 7 minutes without another E4 error so it appears whatever caused that initial error was resolved internally to the system so lets wipe the fault record clean and simply move on…”
Instead of repeating the E4 error, ultimately causing us to return to Mrs. Gillacuddy’s home, the system resolved the issue itself and determined it not significant enough to inform us via another E4 error.
People, I can’t stress enough the significance of this…
The dictionary states the definition of algorithm as the following…
We always need to be conscious of the fact that inverter based equipment is indeed “computer based” equipment…I stress this in Section X of my troubleshooting curriculum where I speak to the need to check for proper ground in the electrical service of the home / building where we are installing a GREE mini split.
In the 1980’s when computer logic was first being introduced into HVACR equipment, it was scary for us to think the equipment we would be installing and ultimately repairing had micro processing ability. Today, we all have a microprocessor in our pocket with more power than many of the computers that landed man on the moon in 1969…its our smartphone!
GREE uses the computer logic of their systems in ways that are unmatched in the HVACR industry…the example I gave of the COMPRESSOR EXHAUST, (DISCHARGE) HIGH TEMPERATURE PROTECTION is just one example.
Keep an eye out for an upcoming “IT’S A GREE THING” article going into more detail about the unmatched onboard diagnostic capability of the GREE inverter mini split.
See you soon!
