Those are thermostat terminals. The schematic makes it seem like the blocks to the left and right are separate components, but they are all thermostat terminals from a single thermostat.

Hey Jersey Mike! Can a 15k auxiliary heat strip be wired on one breaker or both breakers have to be wired? In other words can one side be used?
@JerseyMikeHVAC3 күн бұрын
Are you asking if you can use one breaker and power line for the heat strip and the air handler so you don't have to run an additional power line on a separate breaker? If so, my advice would be to put in a small sub panel by the air handler off of the existing electrical line (assuming it's sized for a 15k heater) and then split it with separate breakers from there. You can also call the manufacturer of the air handler and see if they offer a breaker kit for retro fitting heat strips that will serve your purpose. Most do.
@cre8tive313 күн бұрын
@@JerseyMikeHVAC Mike, I have the breaker kit, I just wanted to know if it is possible to use 1 breaker out of the 2 on a 15 or 20kw heat strip just like I would use a 10kw with 1 breaker since there are 2 heat strips on both the 15 and 20kw heat strip. I have a 10kw, a 15kw and a 20 kw for a Goodman 4 ton variable speed air handler and an inverter variable speed heat pump.

@cre8tive31 You can wire up to one breaker and then jumper over to the other.

after watching a few times i now understand what all the wires do,im just having a tough time wrapping my head around what i can do to install this C adapter for the homeywell T9,i have an okder lennox ac with no Y terminal,my tstat is a 3 wire cooling only so i have R,W and G wires,it tells me in the C adapter manual if i have no Y terminal it wont work for my system,im figuring if i can use another terminal to "fool"it maybe i can get this thing to work,im going to go back and study your video some more thanks
@JerseyMikeHVAC7 күн бұрын
The white wire should be in your Y terminal at the thermostat (originally). That is your Y wire. You don't need W. At the other end of that white wire at the air handler, that white wire will connect directly to another wire that goes straight out to your outside unit. You can try to use that wire as your "Y terminal". The other wire from the outdoor unit is a common wire coming back and should land inside the air handler. Make sure you remember the original wiring because you'll have to put it all back if that doesn't work.

So my blowers are not coming on would I then jump RTG on the thermostat and see if the actual thermostat is bad?
@JerseyMikeHVAC9 күн бұрын
Yes, jumpering R to G should start the blower motor if the thermostat is failing to do it. There are some systems with control boards however that will activate the blower on the Y signal (even if the G signal is not making it). Units with fan relay boards in them (no control board) are the ones that rely entirely on the G signal to activate the blower.

Hi. Thanks for the video! I do have a quick question... I just finished installing a smart thermostat for my boiler and I connected the thermostat with the R (load) rather than at the end with C. Is there a good practice on that? In your diagram we can see the C from the transformer goes to W of the T-stat. Mine would go to the C of the motor. What's your thoughts?
@JerseyMikeHVAC9 күн бұрын
That's perfectly fine. It's a simple circuit and you can go either way with it.
@soufianemess76818 күн бұрын
@@JerseyMikeHVAC I was thinking the same.. except when your t-stat is having R from the transformer connected to it.. you either need to shut off the electricity completely before manipulating a t-stat or be careful with the wires (R) when pulling off the t-stat. I feel like you gonna tell me the best practice is anyway to shut off completely electricity before doing any work :D thanks for the reply
