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 am trying to install a thermostat and I am not sure where to put all the wires... it is for american standard freedom 90 two stage - furnace and air conditioning

Should be like this:

Y from furnace goes to Y on thermostat (yellow)
C from furnace goes to C on thermostat (usually blue)
G from furnace goes to G on thermostat (green)
W1 (first stage heat) to w1 on thermostat(white)
w2 (second stage heat) to w2 on thermostat (black)

Doesn't sound like you have a heat pump but if you do "o" will also have to be connected which is the reversing valve.

Replacing 9420 robertshaw hooking up 6300B honeywell. I have a wire (W2) i don't know what to do with?

If you have a single stage furnace, you do not need that wire....if you have a two stage, then you cannot use that thermostat because it will not do 2 stage...

I have a honeywell thermostat model # th5220d1003-0636 & need to know what connections to make for gas forced air heat.

This is a Focus Pro 2 heat,2 cool thermostat. If you are connecting this to a single stage(1 heat) residential furnace then your connections are: At the thermostat the R and Rc therminals are internally connected so you can connect your R terminal wire from the furnace to the R terminal at the thermostat(this is your 24 volt supply for both heating and cooling. The W or W1 wire (heating) from your furnace you connect to the W1 terminal at the thermostat. The W2 wire from your furnace(if your furnace is a 2 stage furnace) you connect to the W2 terminal at the thermostat. The G wire from your furnace(indoor fan) you connect to the G terminal at the thermostat. The Y1 wire(cooling) from your furnace you connect to the Y1 terminal at the thermostat. The C wire(common or neutral) from the furnace you connect to the C terminal at the thermostat.

Goodman heating system -gmt1155b is not providing enough heat.

if you are using a single stage with just a W connection not a W1 and W2 then it may be wired to the W1 connection on the furnace contro board. in that case it will only run in first stage. the easiest thing you can do is run a small piece of wire between W1 and W2 on the furnace control board. if you dont have a W1 and W2 connection on the board then its not 2stage, if you have an extra wire at the stat you can get a 2stage stat and wire W1 and W2 individually.

Honeywell Thermostat

Make sure G from indoor unit goes to G on thermostat for fan continous fan, if that doesn't work and you have 24 volts to R and C then the t'stat is bad.
For 2nd stage heat or aux.heat, on the indoor unit you need to make sure the wire W2 from the indoor unit goes to W2 on t'stat.
You don't need any wires from W1on the indoor unit to W1 at the t'stat because with a York heat pump Y1 is the contactor which turns the compressor on and you will get 1st stage heat, and for cooling the t'stat will also bring on O which is the (reversing valve) or cooling changeover relay for the cooling mode.
C = common usually black wire
R = hot usually red wire
Y or Y1 = contactor
W1 = 1st stage heat not needed for heat pump
W2 = Aux. heat indoor heat
G = fan
O = Cooling changeover relay
B = Heating changeover relay
L = System monitor
E = Emergency heat relay
