I had an electrician that is a friend of mine wire up the system, but I
believe it's not running at its optimal settings. I seriously need some
help on wiring my thermostat so that I can fully use the potential of my
I currently have the following setup:
HVAC Unit - Carrier 50JS-048 (4 ton - Heat Pump)
Heater Strip - 20KW - CPHEATER054A00 (Carrier 036-060)
Thermostat - Totaline P274-0200 HP
This stages for this unit should be: 2H - 1C
The wiring to the Thermostat is as follows:
S2 = N/A
S1 = N/A
O/W2* = Orange
Y1 = N/A
L = N/A
B = N/A
R = Red
Y/Y2 - Yellow
G = Green
C = Brown (common)
W/W1 = White
Currently the W/W1 is wired to only the 1st stage of supplimental heat. The
2nd stage has obviously never worked. Reson I know this is that there is a
Blue wire in the Thermostat that is not connected and on the unit side it is
wired together with the Gray and Violet wires also connected to the heater
strip. I was wondering it I hooked the blue wire on the O/W2 and jumpered
it to the W/W1 connection if it would fix the problem without doing
something to my unit.
Please help me out on this so I can get some real heat and not this luke
No problem.... here's the very best help/advice you can get....
Call a *competent* HVAC tech to come correctly wire it up.... *most*
electricians don't have a clue about controls as you have found out.
Noon.....electricians thought process......Black = hot, white neutral.......black not always, hot
A friend of mine who is an electrician...thinks this way and has for years.
He has been in HIS OWN business for 20 years....
I don't see how he does it
and dont forget gold, silver, none (my favorite);

And I don't think I've ever seen a gold one, not that I deal with a lot of
The other formulas that I've found useful over the years are the triangles
dealing with E, R, and I...as well as W, V, and I.
I haven't seen that one, but I was taught to make a triangle with a
horizontal line bisecting it.
E goes in the top portion of the triangle with I times R in the bottom.
You cover up the one you want to calculate.
To determine E, you would need to know I and R and multiply them to get E.
To get R, you would devide E by I.
To get I, you would devide E by R.
You can make the same triangle with W, I and E, W being Watts.
W is in the top section like E was before.
Obviously, this newsgroup isn't here for helping someone out. Must be from
the lack of knowledge of the question I have previously asked. Anyway, the
big problem is the lack of documentation from Totaline(Carrier). I just
figured there were a few competent HVAC technicians that may have configured
this thermostat before and could assist me.
Funny thing is, I have asked two local HVAC technicians on different
occasions to look at this already and they didn't know what to do when they
saw a thermostat that doesn't have an "E" for the supplemental/emergency
heat. Maybe they have never installed 2- stage heat pump before.
If you apologize to Noon-Air in this forum I will post the
installation, start-up, and operating instructions for this
Lucky for your brain dead electrician friend, it also includes the
wiring diagrams needed to make your heat pump with resitive heating
apologize or go pound sand. and oh, there's no shortage whatsoever of
documentation from Totaline......if you're in the trade.....
No, it isn't.
It's here for techs to discuss the trade with each other, not to dispense
free information to homeowners who provide us with partial information
about their systems.
IOW. we're here for our own information swapping, not yours.
You think we can't answer your questions??
Well, just for that, I'm going to prove you wrong and answer them all,
Is that the response you were expecting??
Sorry to bother everyone with this post. I was only hoping to get some
simple help and the slamming started about an certified electrician wiring
up my unit. I didn't know there was such a hatred among the trade towards
such another profession. However, I did however pay two different HVAC
technicians to try and fix the problem. One of them charged me $75.00 just
for coming and looking at it (who really wasn't comfortably familiar with
Carrier or Totaline) and the other I refused payment because he didn't do
anything to fix the problem, but I gave him $50.00 just for trying to help
me out. So for your information, I wasn't trying to get anything for free.
I'm sorry I caused such a problem and thank you for trying to helping me
the problem we have is why didnt the hvac contractor who installed
your system also wire up the low voltage controls?
What? you installed it yourself and then thought you'd cut a fat hog
in the ass by having your friend electrician wire it up? An
electrician is no more qualified than a plumber.
well I already told you, all you have to do is apologize to noon-air
and I will gladly give you the critical information you seek......FOR
