Sorry to hear you are having trouble. You may have a newer or older version of this thermostat. If you can find the relevant manual for it you should be able to better decipher the settings.

You are absolutely right, a ring terminal is a much better and more professional connection! We teach a lot of classes and sometimes have to squeeze a video shoot in as time allows. Unfortunately, we sometimes rush and mis the little details.

Great question! This will be a magnetic solenoid and will require constant power to keep it engauged.

@jsoriongroup Do you find the resting/unpowered position to be cooling or heating?

It will depend on the how the manufacturer set it up. We use either "O" or "B" to engage the reversing valve. "O" is energized (24-volts from T-stat) for cooling. Meaning if no "O" signal it will run in heat mode. "B" is energized (24-volt from T-stat) for heating. Which means with no 24-volts coming from the "B" terminal on the stat it will default to run in cooling. Most modern thermostats are capable of both "O" and "B" functions but may require you to select or change which function is needed for the system in use in the menu.

Thanks for watching. We're always happy to hear it helped someone. Thanks again.

I love VR Technology and it's application in training and simulation. It's still very new in HVAC as a whole. I suspect with more time we will see it used in more training for the next generation of HVAC techs.

Great Catch! Thank you. We are a pretty small operation and unfortunately might have an oversight here and there.

The Thermostat I used in this video was an EcoBee. It does not require an outdoor sensor.

I love the energy density and heat output of Natural gas. I only wish it was that price in my area!

It's unreal what some companies charge for NG. The exchange market price is around $3/mcf or 30 cents per CCF. Our utility claims they pass on their cost with no markup, but they charge .60 to .80. You say yours is $1.70 and the host says his is even higher.

I did not include any information about the Ecobee sensors in this video, as it was already packed with information. I may create a separate video focusing on the room sensors, as they can significantly impact the thermostat's operation. The thermostat has a setting to use a specific remote sensor for scheduled heating and cooling. Additionally, it can calculate an average temperature by combining readings from the thermostat and connected sensor(s) to provide a more balanced temperature throughout the home.

I have the same question… did you ever find out how?

Yes. Enter the Tech menu and scroll to "Program Options". It will appear as (PrOG) on the screen. Then use the + or -- buttons to select "0" days. This will stop it from running the schedule.

While you can adjust the timing for the second stage to come on in heating or cooling there is not an option to turn "off" the second stage setting with this Thermostat.

I find it interesting that a thermostat with so many settings lacks a fan-only mode. While many homeowners might not use or understand the purpose of this feature, perhaps that's why Ecobee chose to exclude it. Thanks for the comment!

I share your concerns all the way around. I am very concerned, especially here in California, as to how the insurance industry will handle this. We even discuss the unlicensed contractor and the "handyman" out there in our A2L trainings. Your are on target with your concerns, and your not alone. Thanks for chiming in.

Thank You! I started growing it as a tribute to a great friend and fellow HVAC Tech who lost his battle with cancer.

Thanks for your question and input. R-32 was invented in 1964 and has been very widely used in blended refrigerants for quite some time. R-410A is a blend of R-32 and R-125, so most of us have been sorta-kinda using it for years. R-32 is a component in many common refrigerants currently in use and is a component in some of the newer A2L's including R-454B. As far as A2L compliant tooling. I can't speak on what is required in Japan, but here in the U.S.A. the EPA unfortunately is the party calling for compliant tooling. Probably safe to say that we will see some requirements from OSHA and others in the near future as well.

Thanks for the comment. Yes, it has been used all over the world for some time now. The Kigali amendment to the Montreal Protocol is the driver for the low GWP transition. Here in the U.S.A. we did not sign on to it until much later than most of the industrialized world. So basically we are way behind and you might have noticed there seems to be an effort to get us caught up. That is the main reason, (my opinion) that the A2L transition is happening as fast as it is. Most of those places that have already switched, also allow R-290 to be used in air conditioners as well. Currently the EPA limits the use of R-290 to about 1 pound-1 ounce. So, we will not likely see it used in air conditioning here. For anyone unfamiliar, R-290 is straight Propane.

My exact thoughts!!

Love the "I make ice water" as a former chiller mechanic myself! Also an R-22, R-12 and R-11 fan. Unfortunately, California is going even further. We will try to do an update soon on SB 1206 which is an HFC phase-out plan that is far more restrictive and much faster the the EPA plan.

Thank you Mr. Afram for your input. You are correct. We actually offer an 8-hour class on the A2L transition that includes an ESCO certification test. Unfortunately, we can only fit so much info into these video's and I do my best to get the key points out. My intention and hope, is that our industry will start paying closer attention to this and what is happening overall. I am also trying to get folks to understand they should do the research, or get training. Our industry is changing, and will continue to change. A2L's are just the next step, more change is coming!

@@jsoriongroup Still?? why use it when there are A1 non-flammable, non-explosive and freely available?! see ASHRAE 34 table which all have to apply cause its the USER safety and nothing to do with engineers

@@neilafram663 The Kigali agreement is what is driving this low GWP transition. The EPA has set the maximum GWP value at 700 for new AC equipment manufacturing. Pretty much all of the A1's your referring too have a GWP above the 700 allowed value. This means that the equipment will (actually has already begun) be designed and contain the new low GWP refrigerants that are slightly more flammable than the A1's we've been using. You can absolutely continue to use A1's as long as they continue to be available. However, soon you will NOT be able to purchase new equipment that contains an A1 refrigerant. A2L's will be our future. I highly recommend everyone become familiar and seek training. Go to an appliance store and look at the refrigerants used in household refrigerators. You will see lot's of R-290, which is straight propane. This is our current reality. Thanks for reaching.

All of that came in my universal

So ah everyone goes and buys new tools to accomodate the A2L. How long before the EPA comes and moves the goal post again? One BIG $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$making racket!

The simplest answer is regulation, but propane is also more dangerous, particularly in drier areas, because of the flammability.

@@jsoriongroup We have propane piped through our homes already in !!/2 inch PEC pipes! The flammability argument is stupid and you know it... DOW's lobbyist, is the correct reason...

We also have like 20 gallons of gasoline in our cars...

We also have 24,00 Jules of electrical energy running through the average Americans home's walls...That's about 6oz of TNT.

Are you looking for an expansion valve there in the islands?

It depends how bad the valves are. Reversing valves need a proper differential of pressure to move as well as a good coil. A compressor with really bad valves/low differential pressure might not move the valve.

Sorry, the Johnstones are independently owned, and we don't know Erick over here...we DO have an Eric!

I wanted to be sure the sound was in there. Otherwise, how will they know?

I agree
