I am a service technician trying to install a Totaline p474-1050 stat to work for one stage heat gas one stage cool.. I do not have the operating manual just installation... In the installation manual I could not get my advanced settings information that i need ... so i can go thru the settings to program it right.. the Owners manual has that info.. how do i find out what options are which with out manual ... or how can i find the owners manual for this stat... I think it is dumb they put that in the owners manual because what if some customer reprograms the stat on accident .. but any ways do you know how I can get an owners manual for this stat

Hello Stephanie Sakata,

I found 2 (two) "TOTALINE" manuals...

These little beauties all work pretty much the same...

Put the slide switch in HEAT MODE...

Push the "HOLD".. (which keeps any/all
clocks/gadgets and BACK-SETS off)...

and ADJUST THE TEMPERATURE where you want it...

ELSE...
Read these manuals (close)...

Single stage cooling and 2to3 stage heating thermostat. A 2 stage heat t-stat will/should have the option for a heat pump and aux heat in the installation configuration.

See if there is 124 VAC across the common and the red wire. If not then the thermostat transformer inside the unit will have to be replaced or the fuse changed if it has one(not likely).All t/stats are not the same. If your T/stat doesn't have a provision for the 2nd stage or emergency heat then you have the wrong T/stat That will definitely blow the transformer that supplies 24 vac to the control relays

If you have a two stage cooling system, you are probably unaware of its turning the second stage on and off unless you are right there listening to it or have the proper tools with which to tell. Most of the times, it is just a higher speed that the compressor runs on with a change to stage two.

Many times, a two stage cooling stat is installed in a single stage system because that is what was on the service truck. If so, it will operate the same on first stage as a single stage will. Usually the tech gets into the setup and changes the configuration to make the stat believe it is only has one stage. Many people may think they have an option that's not there.

Just a possibility.

Your t-stat should be set up so that the furnace is the second stage heat and also emergency heat. First stage (heat Pump comes on) sometimes they use Time to start 2nd stage, sometimes they use outdoor temp and this all bepends how bryant has set it up, without a model # I cannot tell you but send it and i will look in somebooks i have to tell you.

Hi, the problem is you have bought the wrong thermostat for the unit if it is not a heat-pump. A heat pump will have W-1, W-2 for heat strips, and Y-2 is for 2nd stage cooling. G is Green for Fan, R is Red for Power, Y is Yellow for cooling, and W would be for Heat. This is all you need if you have gas heat, Orange is for a reversing valve for a heat-pump, and the blue is also for the reversing valve on a Rheem heat-pump. The stat you need will have these terminals, if you are sure its not a heat pump, which I am sure you would know. The stat you need has these terminals. RC and RH. It will have a Red jumper wire connecting the 2 terminals. This is where the Red wire connects, to either one, as they connect together. Connect G to Green, Y to Yellow, and W to white. Since you only have one control transformer, that's why the stat has RH for Red Heating, and RC for Red cooling tied together. Just hook the red coming in to either one. You need only, R, G, Y, and W, to run this unit. Look at your old stat and check the terminals. A heat-pump, uses many more conductors to operate it. O or orange for the reversing valve, blue also depending on the unit. C for common, W1 for stage one heating, W2 for stage 2 heating, Y1 for stage one cooling and Y2 for stage 2 cooling. This stat is used for a commercial unit with multible stages of heat and cooling. If you have a common wire and no batteries on the old stat, go to the indoor unit, remove the panel, and see if you have a common wire hooked up, such as the brown, black, or maybe blue. If so, you will need to hook it up at the stat if it has a C terminal. If it has batteries, just take all of the extra wires and shove them in the wall. You won't need them. Just the R, G, Y, and W, and you will be back on line. Very easy.
Please rate me. Take it back and have them sell you the right stat. Please keep me posted and I will be here if you need my help. Thank you for using Fixya.

getting heat in the cooling mode leans toward the reversing valve in the outside unit. it changes the flow of refergerint so that the hot air you get outside in the summer is blown inside in the winter. another possibility is that the reversing valve isn't getting 24v check to see if you have 24v at O and C either at the t-stat, furnace, or the outside unit. if you check at the furnace rember the safty switch for the lower door if that switch is open you will have no power. i would look at the t stat first if you have 24v there go to the outside . 24v present outside will mean a bad valve or board, no 24v means a bad or broken conection in the control wire between the stat and the outside unit(usally the orange wire)

Hi,
Here is a tip that will help you with that...

sounds like a wiring issue to me

either there are wires going to the wrong terminals on the t.stat, or there is a physical problem with 1 or more wires somewhere

it is also possible that the new thermostat will not correctly control the unit that you are trying to operate. Unfortunately, just because it has all the right color terminals, does not always mean that they all operate the same.

Good Luck!

R comonY cool W heat G fan C other side of 24 unless you are battery operated. On the back of the Tstat tou should have switch that says gas or electric this controls how the fan operates. If not go into programing and program 1 stage heat one stage cool.Let me know I will walk you thru this.
