SOURCE: installing a honeywell CM900 wireless programmable thermostat

the analog unit uses just two wires for heat. red - white. there is a heat anticipator setting that must match the burner current. check your programmable specs and follow instructions.

SOURCE: Installing Honeywell RTH7000 - I have too many wires!

check to see if the B terminal is on the new t-stat if connect to it , but this terminal refers to heat pumps and is normally use to energize the reversing valve on the outside unit and not used on ac units , but normally the tag O/B is the same terminal on therostats

SOURCE: how does transformer hook up

if you just replace the unit and it is working, no your do not need the tranformer. The unit is getting power from the furnace. For reference though. The black and white wires are your 120 volts. Black hot, white common. the 2 screws are your 24 volts

SOURCE: Honeywell T8411R 1028No power to the thermostat; breakers are not

site shows this thermostat is a non programmable unit and has been discontinued. none of the info sheets including a pdf shows a replacement battery. this thermostat operates off line voltage only. check for a control fuse or breaker on your heating unit.

SOURCE: I have a new York hybrid heat pump/gas furance

Did they check the sensor in the plenum. You are suppose to have bonnet sensor to switch from heat heat pump to gas whaen it is to cold for the heat pump. The bonnet sensor may be to bad. The unit is cycling ever five minutes because it may have five minute time delay.

My unit is a Honeywell and not a Muirfield.97-4118/5-89 and it will not work on auto but works on manual.


If it's a new thermostat that you have recently installed, check your installer configuration. Make sure the tstat is set up for gas or electric heat, depending on what you have. Some t-stats also have a small switch on the back to switch from gas to elec. A gas furnace has components to control the fan, electric unit uses the tstat to control the fan. Hope this helps!

Replaced Thermostat and now Blower Motor will not run


Sounds like a set up issue on the tstat. You say this is a packaged unit, inside the machine you should find where the tstat wires hook up. Typically red is power yellow is compressor orange is reversing valve white is emergency heat green is blower. Put red and green together, test blower. Then red green and yellow, make sure blower works again. If blower runs both ways it's either the tstat wire or tstat itself. Make sure you are landing wires on dedicated heat pump terminals, make sure in settings you are set up for heat pump with back up electric heat and TSTAT CONTROLS THE FAN. Good Luck. Also if there is a switch on the tstat for gas or electric on the back you want electric.

Rheem water heater flashes seven times ,it is in lock out mode


You have Honeywell electronic gas control valve, and error code is 7 flashes.
Probably you have power vent model.
One manual from different company says: "Reset gas control using on-off button on front of control, replace flammable vapor sensor, replace gas control thermostat.
But with Rheem you also need specific steps: Remove gas burner and look for broken glass vial, and then blow out arrestor screen air intake using compressed air, clean burner parts, check for unobstructed venting, you will need new glass vial from Rheem depending on year and model number of water heater that appears on label on side of unit, or they may not have a repair kit for that model, and you might need a new gas control valve depending on model and how extensive problem was
You have Rheem water heater.http://waterheatertimer.org/How-to-repair-Rheem-FVIR.html

Where is the thermostat located on a rheem fury 81v52s ?


Hi, The thermostat on most hot water heaters is part of the gas control unit.
if you disconnect the wiring on an electric unit or the piping on a gas unit the whole controller should screw out. Make sure that the electrical power is off, gas **** is closed and water tank is empty.
Hope this helps.

I have a Rheem 41VRP50N water heater. The water I am getting is luke warm on a good day. The burner fires up when I turn the thermostat to the highest temperature only. I drained the unit and flushed...


This condition can be caused by 4 different problems, or combination of these problems.
Good indicator would be to check temperature of water inside tank.
Put bucket under TP overflow tube and release water into bucket, then use cooking thermometer to gauge temperature. Stand back from scalding water that can shoot out of overflow.

If tank temperature is 120-130:
1) Crossover is suspect:
http://waterheatertimer.org/Crossover.html

If tank temperature is low:
2) Bad gas control valve thermostat is suspect.
I believe Rheem 41VRP50N has Honeywell or White Rodgers electronic gas control valve.
Open following link to identify gas control thermostat and see typical error codes.
http://waterheatertimer.org/How-to-adjust-temperature-on-water-heater.html#Honeywell
Replacement gas valve can be purchased from Rheem.

3) Combustion parts and tubes need cleaning, and bleed gas line for air and water contaminants.

4) Water heater has sediment build-up coating burner transfer surface and covering thermostat.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html
Year of manufacture for Rheem water heater is 2nd two digits of serial number, so XX03.. would be 2003.

Whats' so hard is the Honeywell thermostat has a built in 1@ differential. It is not adjustable.
You might ask your installer about a time delay relay installed in the furnace to break the thermostat heat wire (usually white wire).
Most time delay relays are 90 seconds. But that might be enough to reduce the furnace cycling.

Manual Thermostat replcaement with Programmable Digital unit.


Hopefully there are markings on the old t-stat as to what terminal is what.
on the honeywell 8000 use the heat pump labeling and then the standard wiring would be
R- red
AUX-white
Y- yellow
B- O/B
C- black
G- green
There should not be a bare wire, it probably just has the insulation stripped back way too far.
You should probably open the furnace and compare the terminal label in the furnace to the wire color. normally yellow and blue pass through the furnace and are wire nutted to wires going to the outdoor unit. In the furnace the white wire will connect to the w or w1 terminal. also, you will need to set the Honeywell stat to have the following parameters.
170-7
190-1
200-0
other parameters that I did not specify, you may read the manual and make your own decision but I recommend factory settings for the other parameters
