What kind of system are we working with here?
I'm going nuts here. Make a terrible mistake and took wires off old therostat without writing down which terminals they were connected to or taking a picture.
Is this a heat pump or standard furnace and AC?
Its a Payne central air/central heat inside unit.
I don't know if there is a heat pump. Its all electric, no furnace.
So just a standard system, correct?
Yes, i suppose. I don't know shit about HVAC
I need to know if it's a heat pump because they get wired differently
do you want me to send you some pics?
How would i find out if there's a heat pump?
How about some make and model numbers of inside and outside units?
ok. hold on let me get those for you.
ok, indoor unit is Payne Model PF1MNB048
outdoor unit is a Carrier
Model is PH10JA048-G
Outdoor unit is typical central AC unit I suppose.
This is a heat pump and fan coil unit
So typically red would go to Rc and Rh, green to G, yellow to Y1, orange to O/B, and white to E and Aux tied together
Don't need the black
ok hold on. Let me send you of pic of my thing and how I have the wires now.
ok there it is. What a pain it was to do that. Sorry.
No problem, do you have back up electric heat?
ummmmm i don't know
i have electric heat period. I don't know if I have back up
Well, heat pump supplies some heat, but usually in colder climates, you also need backup electric heat
would it say on the unit somewhere if there was back up? is the red wire supposed to be attached to the jumper like that?
I live in Florida, so I am going to guess that there is no back up.
No the red should go down and be put into the terminal either RC or RH
The rest of the wires look OK. Did you turn power off before starting to wire?
oh, ok. which terminal should i put the red one in? should i try each one?
and there is only R or RC, no RH
Take and turn power off, doublecheck all wires to make sure they are firmly seated. Bring the red down and put it in the R terminal next to the jumper wire and tighten down securely
ok. oh, leave the jumper in? put the wire in with the jumper still in there too?
Yes, you need the jumper
ok cool. Let me give that a try and I'll get right back to you.
thermostat is going through its reset process.
as soon as its done i'll let you know if it worked.
OK, did you go into the setup menu and set up the system type as "heat pump"?
it doesn't have that function. this is a very basic thermostat. there is a switch inside to go between electric and gas, but that's all. its switched to electric of course.
OK, I just noticed that
i'm so angry with myself for not taking a picture of the original thermostat wiring before i disconnected it. its till flashing right now, some sort of protection thing for the condenser. it takes a while before it actually kicks on. sorry.
OK, let's wait and see what happens
ok its done flashing. nothing happened. the airhandler did not kick on. damn.
should i call my AC guy? have a pro come over?
OK, I'm thinking you may have blown a fuse on the board or worse yet, the transformer
this is maddening. i played with the wires quite a bit today, trying different configurations. got the air handler to kick on several times but not the outside unit.
oh my. that doesn't sound good. what would cause that?
Having the wires in the wrong place, for one thing
could the thermostat be faulty?
i called an hvac guy and he said to try several different combinations. he said nothing bad could happen because its low voltage.
i guess he lied?
Most air handlers have a fuse or circuit breaker on the board.
i didn't use the blue or the black wire at all.
Do you have a voltmeter?
no. i don't. i should get one though.
i guess i need to call someone to come out.
what a mess.
OK, without that I can't have you check for 24 volts. It looks to me that from the picture, the wires are in the right place now. I just think you may have blown a fuse on the board or the transformer.
ok. is that a big deal to replace?
like, is it expensive?
No, not really
ok cool. I'll call someone and them come out tomorrow or whatever. thanks.
No problem. Good luck and thanks for using Just Answer. Please don't forget to rate my service. Feel free to post back with any further questions.
