The switch on the right side of the T87 is for the fan. Down is the auto position which will cause the fan to run only when needed. Up is the always-on position, used to circulate the air constantly. If you want to shut down all heating cooling associated with this thermostat you need to look at the switch on the left side of the stat. To the right is heating, center is OFF, and left is ac.

Bought new thermostat model ct87k but old Honeywell model I have was hook up by black and white wire not red and white , so how do I hook up.


The two wire Honeywell T87 and CT87 is nothing but a switch in a control circuit. Wire color is not important at all. What is important is the TERMINAL DESIGNATION those wires are hooked to. Soooo....take the wire off of the sub base of the old stat terminal marked 'R' and attach it to the new sub base terminal marked 'R' and so on. Wire COLOR means nothing at all in your case.

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

I would switch to a two wire heating only stat It sounds to me like they have the boiler wired into cooling side. Do you also have to set switch on your t-stat to cooling or leave it on heating. Just curious. I would still go with two wire stat. Thanks.

One thing you can try is to remove cover, it just snaps in place.There are two plastic leveling posts at top two sides. You will need a small level commonly called a torpedo level to set on these leveling points.It should be very close to level,bubble in middle. If it's not look at base plate against wall and locate two lower mounting screws there will be a small slot where the screws go into wall to allow for slight adjustment.You will need a small screwdriver to back these two screws out a little maybe 1 turn.Adjust thermostat base so that level has bubble in middle and carefully tighten the screws,keeping t-stat held level. This should help some but it is not unusual for set temp. ont-stat to be off 3-5 degrees from thermometer reading. Hope this helps you.Thanks.

We have a round thermostat made by Honeywell. I


Hi,
The thermostat that you have is position sensitive. By that I mean that you need to have it in the right position for it to work correctly.
When you have the ring off of the thermostat loosen the two little screws and pull the thermostat away from the subbase. On the subbase you will see a line that needs to be level. If it is not level then the mercury bulb will not be in the right position to start and stop the furnace. Level the subbase and reassemble the thermostat and your furnace should start to work properly. If not then the thermostat is probbaly bad.
When they go bad it is often becasue ot the little arm that you refeered too. That is a small heater than actually fakes the thermosat into thionking that it is hotter in the room then it really is. This makes the furnaces shut down a bit early to combat overshoot. Adjusting that will determine how much time before the furnace hits the shutdown temperature that it will actually shutdown... got that?? In others ward it is probably a good idea not tp mess with that unless you know what you are doing. However the heater can burn out and create problems.

So, check that the thermostat is level and if not get a new t-stat...

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

Hey John, man that ole T87 has been around for a hundred years and I have installed many of them, but I cant remember the letters on the wiring. Seems to me that it is R-W-Y, any way you will use the R and W. I have a t87 at home still in the box and I could wait till I got home to help you but Im sure its the R and W terminal. Dont forget to set the heat anticipator. Set it the same as the current value of your gas or oil valve.
