I have a Totaline CR100 - a non programmable tstat.
I want to replace it with a Ritetemp 6080 tstat - programmable.

My home has a heat pump - both cool and heat are derived from the one pad mounted compressor outside my home.

There are 5 wires coming from my wall and are connected to the currently installed Totaline to a respective letter, as follows:
Yellow -> W
White -> O
Green -> G
Red -> R
Blue -> C
NOTE: Yellow going into W has a jumper FROM W TO Y.

There are 5 wires coming out of the wall. There are 6 letters filled due to the jumper from Y to W.

The new tstat by RiteTemp has 8 letters/connections.

The instructions, as I interpret them, ask that I connect in the following manner:
Yellow ->Y jumped to W, aka compressor
White ->O, (given O/B (will run to O because the Totaline has O & no B?) aka rev valve
Green ->G, aka FAN
Red ->RC jumped to RH - aka power constant
Blue ->C - (on RiteTemp, C is to avoid constant battery replacement

In summary, B will be left vacant.
I will connect the Blue wire from wall to RiteTemp C to provide tstat lighting power??

My question: does this sound right OR am I way off? I am NOT in any way an electrician nor HVAC specialist. I just don't want to "blow" anything up, pop fuses, or worst, catch my house on fire or burn up an expensive tstat or piece of equipment in my HVAC system.

Your help is much appreciated.

A link to see the RiteTemp connection is here: The RiteTemp Support Site - Y, O, B, G, R, C* Wiring Steps (http://www.ritetemp-thermostats.com/YOBGRCstepsR2.html?step=all)

Totaline does not give ANY information anywhere I could find to confirm what each of WOGRCY goes to. After much much time hunting the entire web, I found just a few clues here and there as to what each letter corresponds to and am hoping that my best guess, as seen above is the right guess.

In summary - those of you who are experts in this arena, could you please tell me if that looks correct?

Looks good,, warning just in case, don`t fail or forget to turn off power to furnace
1 little spark can fry the transformer

Just to make certain, if I don't have a furnace, will this still work?

You have a heatpump,, what is it tied to,, to blow the heat into your home?
Where is the power for the red thermostat wire coming from?
The green wire that goes to the fan, what/where is the fan motor?

Guessing you are going to say a airhandler,, does the airhandler have a heatstrip installed for emer. Or backup heat

you have a heatpump,,,,,what is it tied to
Heatpump is a stand alone pad mounted unit outside the home - acts as both the cooler and heater


,,,to blow the heat into your home?
The heat pump, from what I've read, goes one way for cool and the other way for heat via something called a reverse valve or changeover valve. I can't recall which one I have or if these are the save thing.



where is the power for the red thermostat wire coming from?
From what I can tell, the power for the red wire is coming from a 24 volt transformer, I believe it might be ac - I though 24v would be dc, but I read somewhere that the voltage is actually ac... could be wrong, I've not hooked up a meter to test this.


the green wire that goes to the fan,,what/where is the fan motor? The fan, from what I can understand from schematics I've looked at online and from what I looked at up in my attic is the "airhandler" - I think that just blows the cool or hot air created from the heat pump?. not sure. But the only fan I can find is in that unit in my attic.


guessing you are gonna say a airhandler,,,,,does the airhandler have a heatstrip installed for emer. or backup heat
Yes, airhandler, no there is no emergency heat strip.

I believe I should have mentioned in my initial scope that my home is in Phoenix AZ. The coolest it gets here during the coldest of winter is around 30 degrees F... and to get below freezing is not at all common. Whole different story if you go just 30-40 north of the Valley.

Anyway, I sure appreciate your time, effort and input on this.

I did more research this morning as get more accustomed to the jargon used and I'm thinking more and more that this just might be correct. However, in all of my reading, I've seen so many bad things happen that I would like to error on the side of caution... so I'll wait for confirmation from you that know your stuff.
