Hook up like this:
R-RC (jumper rc with rh) unless you have more than one transformer
O-Y/O (depending if reversing is energized by O or B terminal, refer to your manual)

Can you provide me with the wiring instructions, I want to replace the old analog thermostat. I have a roof mounted not ducted Advent A/C and a furnace unit.

The terminal board on the rtu should match fairly closely with the letter designations on the thermostat. R, W ,(possibly W2) G, Y, (possibly Y2) and C. W2 and Y2 are most likely NOT used on a small capacity rtu (roof top unit) as those terminals are for a second stage of heating and a second stage of cooling.

The thermostat terminals should be Rc, Rh, W, G, Y and C (common). IF the replacement thermostat is programmable the common terminal should be used because that allows the thermostat to run on 24vac and not just battery power.

There should be a factory jumper installed across Rc and Rh and that should stay in place as the two terminals are for systems that have TWO different control transformers. Small capacity rtu's will have only ONE transformer.

Some rtu's have a W2 terminal as well as a Y2 terminal even though they do not have the second stages of heat. You have to determine exactly what your system is prior to changing the thermostat.

I have a Hunter Thermostat 44360 7 day Programable and I want to cancel all programs and just use it manually amy help?????

There should be a tiny unmarked hole in the front of the thermostat....if so, the thermostat 'reset' micro-switch should be under that hole. Gently stick a thin toothpick inside to depress the switch and get ready to operate it manually.

If there is no hole, separate the thermostat from its sub-base and look closely at the sub-base for a reset button.

I am replacing an T8411R with RTHL3550 and I have the following wires. Original vs New G=G,R=R,Y=Y,O=O......? I have a W2 and an E wire that go into different screws on original but no seperate terminal...

C is actually a power wire; it provides power for some programmable thermostats. You don't have to connect it on the new thermostat; cover the end with electrical tape to avoid it causing a short. (If you keep that wire accessible, it will be nice for someone who wants to use another programmable thermostat. The ones which can talk to wireless networks require this wire.)

Do you have a heat pump? That is the only time a thermostat uses an E wire.

The W2 wire should go to AUX (third screw terminal from the left) and the E wire should go to E (second screw terminal from the left). See page 25 (27 on the pdf) of the Quick Installation manual for the RTHL3550. This manual is available from Honeywell at .

I hope this helps.

W and W2 wiring on old thermostat...where do they go on the new thermostat?

It depends on the equipment you are connecting the thermostat to. If you have a heat pump, the thermostat must be wired differently than if you have separate heating and cooling equipment. If you have a two-stage or modulating furnace (or boiler), the w and w2 wires will conect for heating, and the y and g wires will connect to the air conditioner. Naturally, some configuring must be done with the new thermostat so that it acts correctly. w-w2-wiring-old-thermostat-go-new-u40lsvyytnuesyuv3fbafhtd-1-0.jpg

I have old Honeywell with 7 wires W2, L, B, G, R, Y and E. Now I have bought Hunter 44155c with six terminals: G, RC, RH, Y/O, W/B and Y1. How can I connect them? Thank you so much for your help!

You need a 2 heat, 1 cool, heat-pump thermostat. W2 is the heat from the heat-pump unit outside, E is the emergency heat inside the house (usually electric), and on the new thermostat you just have the one W terminal for heat. You can jumper the two wires together (W2 and E from the old thermostat), but you will get both heats all the time when its being called for. Since you may have powered heating instead of powered cooling, I would try to get a thermostat that matches up better, otherwise, you might run into more problems than just the terminals, like rewiring the heat pump and furnace/air handler to accommodate the new thermostat. Hope this helps, and if you still have problems afterward, be sure to explain which wires were already hooked up to which terminals and so forth so we can have a little better idea whats going on, sometimes it can get confusing without being there. Good luck and hope everything works out for you!

Is this a heat pump? Look in the thermostat. You should have something like the following.
Red wire to R terminal
Green wire to G terminal
Yellow wire to Y terminal
White wire to W or W1
Blue or Orange wire to the O or B terminal
Brown wire to C terminal.

Let me know what you have in the thermostat. The wire colors are not always the same.

Usually there is a blue wire to the thermostat but in this case it is not. instead there is a black wire. i used that one as blue. now there is no heat. it is a hunter cool/ heater unit.

Red Wire Old to

New RC and RH Terminal

Y Old = W ?

New = Y1 Terminal

G should be for the fan Old to

New =Green Terminal

White is for Heat W2 Old to

New =W/B tremnial

X2 Is used only on 24 volt thermostat that need 24 volts to opperate the thermostat usly not used on most thermostat
To start I would not hook this wire to any thing just yet
Tape it so it can not short any thing Black Wire

Orange Old to

New Y/O Not used

The thermostat on my coleman heat pump has 7 wires labled:g,y1,w1,x,w2,a,r. but the hunter replacement thermostat i purchaced does not have the same labeling it has rc/r,c,y1,y2,w2,e,o,b,g,l.i need to know...

here is some info may help you
coleman = Hunter
g   =  g
y1 =  y1
     =  y2 (second stage you don't have it on your system)
r    =  rc/r (leave the jumper bewteen rc/r)
x   =  c
w1 =  w1
w2 =  w2
a   =  o
     =  b
the "b" terminal is to energized the revensing valve on heat mode
the "o" terminal is to energized the reversing valve on cool mode

Wireing code from goodman heat and air to a Hunter 44360 programa

To get your heat going take the red wire hook it up to R on t-stat. Take white wire and hook it to W on t-stat. Take the green wire and hook it to G on t-stat. that will get you heat. Now I need for you to go to the unit where the wires hook to the furnace circuit board. I need to know what color wires go to what on the board. Might have to take off bottom panel. should only be using 4 or 5 wires. Get back with me and will complete the wiring. Be sure no wires at the t-stat are touching each other as this will short out transformer. So tape them off or cut flush so wire and insulation are flush. ken
