Question about Honeywell Heating & Cooling

1 Answer

I have an existing 3 wire honeywell room stat on a conventional ch system which has gone faulty. I have bought a honeywell DT200 to replace it but this looks like it only takes 2 wires. Can I use this stat as a replacement? If so how do I wire it and what do I do with the spare wire?

Hook up the Red wire to R on the t-stat and the White wire on the W just cut the wire flush with the insulation and leave it un hooked. If those are not the color get back with me. ken

    Take the Red and go to R on t-stat. Then take the blue and hook it to W. Try to turn on furnace if it works good. If it don't disconnect the blue and hook up the yellow in it's place.

Hi I have a hb2400vd2m20 air handler and need to know what wires are needed to hook up to my thermostat its a Honeywell, as of the moment there is no heat pump it just the air handler running. I know there...


Honeywell 5000, 8000, 8000 iaq, prestige, round dial analog, digital Honeywell redlink. 1 heat 1 cool thermostat 3 heat 2 cool thermostat. does the stat u have do conventional a/c and heat pump. red wire is hot wire 24 volts not heating its your 24 volt control power. this will be r on your board and t-stat and red wire. y is for cooling mode and is yellow and will be noted y on both board and t stat. green is fan on the indoor furnace and will be g on board and t-stat and the wire is green. blue is the common side of the transformer labeled b on both board and t-stat. I did not see brown on your schematic I looked up I seen orange which is your reversing valve wire for the heat pump whether its calling for cooling or heat this is what changes the flow of Freon to make it to the indoor coil as warm Freon or cold when called for in heat or cool. the thermostat if a vision pro 8000 needs to be programmed in the installer mode which if this is the t-stat u have u need to read through the heat pump section. the green hooked to the orange doesn't look right on the print but that's the breakdown. http://www.manualslib.com/manual/277678/Haier-Hb2400vd2m20.html?page=11#manual heres your schematic

Disregard wire colors. Instead wire by terminal designation. In other words :
Wire on "R" Terminal on old thermostat to "R" Terminal on new thermostat no matter the color.

We are trying to install a HoneyWell programmable thermostat (model RTH6350) and the colors do not match up. We have an orange wire, blue wire and white wire without a connection. It says to wrap the O,...


T-stat wiring is commonly connected with the following color codes:

On a straight heat and cool system:
White = W on T-Stat
Yellow = Y on T-stat
Green = G on T-stat
Red = R on T-stat

On heat pump systems:
Blue = W2 on T-stat

There is no guarantee that your system is wired using this system so you will need to look in the furnace and see where the wires are connected to. You will have another set, probably 2 wires, going to your outside A/C unit. They are typically red and white but could be any color as long as they are hooked up to the same connections. I.E. blue on R at t-stat and to R on furnace would be OK, it just makes it harder to service the unit if you don't know what wire is for what.

Just check your furnace connections and connect the same wires to your t-stat no matter their colors.

Honeywell DT200 thermostat is not responding to any buttons pressed. Display is showing small flame icon on left of screen and what looks like a battery in top right hand corner. Any suggestions?


The thermostat is calling for heat, and the battery icon means that the batteries are low and should be replaced. If the thermostat is wired to run on battery power alone, replacing the batteries usually corrects this problem. Hope this helps! Jim

DT92E room stat appears to be very inacurate with its room tempreture, our normal room temp is about 22c we have to set the stat at 25c to get heat and the stat cuts out after a temp rise of 1c


All thermostat is calibrated @ difference of 2 degree.to cut in and cut off.
In heat mode, if you keep 25 and your room temp 23. it will start at the end of 24 or beginning of 25 degree.Cut off also @27 degree beginning. Please check Tips & how to do's in Fixya

Installing thermastat


any wire can go to any terminal. unfortunately you now have to hand trace each onre to the device it powers and hook it up accordingly. a daunting task even for a pro. having said that the installer could have used the normal colrs for the usual wiring if you were real lucky. as a general rule the red goes to the r terminal. the yellow goes to the y terminal. the white on a heat pump usually goes to w2. the green powers the fan and goes to g. usually the changeover valve is powered by the o terminal and that is usually wired with an orange wire. that only leaves two more wires. one is the auxilliary or emergency heat terminal and any color wire can be used for that. it will go back to the airhandler and tie on to the w terminal along with the white wire from the stat on most units. or they may have jumped the w and emergency terminal together and hooked the white wire to both. it will work either way. that only leaves one wire and that is the common wire to the stat taht allows it to light up and think and have power. . most stats need the red and a common to work. you may have bought a stat that works off battery power only but since you are blowing fuses it seems you have a common pulled on one wire that you have hooked up wrong and it is creating a dead short , aka a blown fuse. if you go to airhandler and finf low voltage terminal board look for terminal labeled comm . observe what color wire is connected to it and if that is the wire that goes off to the stat. if it is hooked to common and goes with the others to the stat then thats your common and should be hooked to your stat common terminal as outlined in your install sheet. you can keep replacing those fuses till you get it right or take a chance and use an amp probe and a jumper wire . only run an instant and if amps are 4, 5, 6, amps at trans your wrong. only test an instant or you will ruin transformer.probably best if you get a box of fuses.label stuff make notes and good luck. i have gotten in the habit of using a sharpie pen to make copius notes right on the service panel for me and the next guy.

Have an old honeywell room stat (type with round temp knob) and have taken off wall to allow for decoration. Now heating does not work. Any ideas on whether it's broken or alternatively can it be bypassed.


jumper red to white and it should bring on a call for heat. if it does then you probably damaged stat on reattachment. do you self a big favor and go to a digital stat. you probably have a red white yellow and green wire. hook them up same way on new stat. if you have an extra wire you can pull a common and power the new stat off the transformer, if not you can get one that uses batteries. robertshaw makes some good ones 9400 9401 etc. you need straight cool with gas furnace. they are great. no need to get to fancy and avoid the ones with programming and all. they are way to complicated unless your into lots of programming and tech details. plus those old honeywells are almost impossible to get perfectly level on the wall and if they are not level they will perform way out of whack
