Wiring for GPH1548 & Honeywell Themostat Th8320U1008

I have a Goodman GPH1548 2 stage cooling and 2 stage heating via the heat pump. The unit has had field installed heat strips.
Wiring as best as I determine is as follows -
Y2 - yellow
AUX -brown
RC+R - red
O/B - orange
Compress relay 1 - yellow
Fan Relay - green
Compress relay 2 - purple
I have a white wire (W1) where does it go?This unit has a 2 stage heat/cool and aux heat strips.
I am starting to think I do not need the white wire since the rev. value will give me the two stage heat and the 2 stage cool. The brown wire would control the heat strips?
any help is appreciated

the black wire is your common wire, you need to program your thermostat, in the advance mode, to tell the t-stat if your heat pump reversing valve is energized on cooling or heating, is the orange wire connected to your t-stat.= w2/o/b

the fan fill come on with the sequencer (stack switch you call it) it will also come on with the fan relay. on some goodmans the fan relay is the black box on the circuit board. use a jumper to jump red to green, this should bring the fan on sounds like you could have a broken green wire, try using a different wire instead of green

Carrier OEM to Honeywell Programmable Tstat - NEED HELP


you likely have a "two stage" system, but not a two stage heat pump. the first stage is probably the heat pump itself, and the second stage is the auxilliary resistance heat that suppliments the heat pump at lower temps. if i knew the terminals that are available on the new stat, i could advise you on the proper wiring.

I installed a new Honeywell Programable thermostat, When I turned on the AC it turned on the Heater... I followed the wiring but some of it is not making sense... G=Green, Y=Yellow, R=Red, C=Blue,...


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.

No heat, got great a/c....


W1 and W2 are the differences from the single stage to the two stage. Im thinking its your thermostat is not programed for 1 heat / 1 cool. You probably had 2 heat / 1 cool before.

MY HEAT PUMP SYSTEM WILL NOT WORK IN EMERGENCY MODE


the thermostat sub base has a place to connect a wire usually white to energize the heat strips when you push the stat way hotter than the house temp. that is why the strips come on in normal heat. it also has a terminal that is only energized in emergency heat and it also should have a wire connected to it so that terminal can supply power to the strips when the stat is switched into emerg heat . you can identify the terminal from the wiring diagram and if need be jumper w2 wire over to the aux terminal and it will work. they both go back into the airhandler and power the same strips. w2..................................................................................................w2 in airhandler to strips or w2...jumper to aux......................................................................................................................w2 in airhandler to strips.
