Trying to hook up the defrost so it will energize some heat during the defrost cycle. It says run a lead from D on the heat pump to P on the air handler. Only problem is, I seen no P terminal on the air handler's circuit board.
Apparently you can't read a schematic?? or the installation instructions?? This is basic controls, with basic wiring. You do know that Rheem equipment RVs are energized in heat, I would hope What model heat pump?? What model of air handler are you using with it?? What control are you using with it??
Why are you putting in an R22 heat pump when in a year, R22 is going to become *VERY* scarce and *VERY* expensive??
You have already proven that you not a tech, but a home owner trying to DIY. Take a crowbar to your wallet and call a local tech that knows what he is doing.... who knows what else you might have screwed up in the process.
BTW... you do realize that the warranty on *ANY* Rheem equipment bought over the internet is null and void.
This is an EXISTING heat pump that was installed in 2005.
I already called the tech and he says he doesn't know anything about that and furthermore, he is too busy to fool with it. He says he has
100 calls to make on units that are out of service and. Says if my system breaks down, call him.
I did not buy this system on the internet, It was installed by the above mentioned tech.
It's just a simple connection. All I want is for the heat strips to kick in when the thing goes into defrost. I waited till warmer weather to do it so I wouldn't freeze my butt off trying to hook it up in the winter. I looked in the unit outside and the D terminal is already connected to the purple wire. But it ends inside the air handler without being connected to anything. I don't think it takes a highly educated tech guy to connect 1 wire.
There's several years of R-22 out there, in HVAC shops and on the trucks. Enough for a while. The new R-410a, which is marketed as Puron, and some other names. Supposed to do the job nicely. It won't work in the old systems. As the price of R-22 goes up, someone is sure to develop a drop in replacement.
most manufactures quit making R-22 stuff last September..... My suppliers can't even get a replacement R-22 3 ton evap coil anymore.... they are not to be had.
Can't you install an R22 metering device on a new coil? If it won't take an orifice/piston for R22, braze an expansion valve on it. Have you never converted a system over to another refrigerant? I've done a number them.
I assumed he was talking about a cased coil, not putting a coil into an existing case. Good grief, I can't count the times we've had to cut out an old coil, case and all, and install a new one.
The question still remains.... with the HCFC phase-out, does the customer want to pay the almost $2,000 to replace a leaky coil, or put that money towards a new system that has a 10 year unit replacement warranty, will cut their power bills in half, and not have to worry about if the refrigerant will even be available in the next couple of years.
The whole thing is to present the customer with facts, information, and hand-outs to back up what you tell them, and let them make the decission of what they want to do, and if they opt for a new system, let them tell you what system they want you to install so its win-win. Either way, you want the customer to be happy to write that big check, and you'll be doing the happy dance all the way to the bank.
