SOURCE: Furnace doesn't reach desired temperature

On the thermostat if its a manual on then pop the cover off and look for a small dial with numbers on it. Take and move it tpoi a higher number than whats it is set at. Its called a heat anticipater and is supppose to make it so that the unit does not oveshoot or under shoot like what your experiencing. If its a digital oine then you are going to have to configure the setting in the insdtallers menu.

SOURCE: Furnace doesn't reach desired temperature

One of two things you can try. Do you own a volt ohm meter? Anytime your unit cycles short like it is doing the control circuit which on this one is 24 volts that engages relays and controls the gas valve to open and close. I am thinking the heat exchanger is getting so hot it is tripping the upper limit which for the most part is around 180 degrees. So next time it turns off take your ohm meter and with the power to the whole unit off. Either turn the breaker off or there is a light switch that is real close to unit turn it off. Undo the two wires to the gas valve and ohm them out. You should have continuity if you get nothing check each limit switch should have a couple. Undo wires to them and check. If you find one that is open more then likely the upper one. They are a safety device that keeps the unit from getting too hot.

There might be another option increase the speed of your fan motor to get the heat out of furnace quicker. Look at the circuit board notice the fan wiring going to it. The Red wire from fan is low speed look to see if it is on HEAT on the board. You should have 4 speeds to pick from you could take the black off of COOL and swap wires and test the unit by doing that. I'm going to put a solution on this so I can come back to it quicker. Even though we a just testing it for now. ken

The display on my thermostat T8400C 1024 isn't working. Everything else works but the heat and the flame is not igniting either. Please help.


Sounds like a manual limit needs to be reset (thermal disc). Generally the manual limits are around the exhaust - backdraft, or burner assembly - flame rollout.

How do I change my Honeywell FocusPRO6000 TH6110D1005 thermostat to from Fahrenheit to Celsius?


Press and hold the up arrow and fan buttons until the display changes. Then press Next until you see 14 in the display. Change this value to 1 (with the up and down arrows) to get Celsius. (O is Fahrenheit.) Press Done to exit and save the setting.

The manual is available here: http://customer.honeywell.com/Honeywell/ProductInfo.aspx/TH6110D1005 . Scroll to the bottom and choose a manual then press Download. This particular section is in the Installer's Guide.

I hope this helps.

Hello
Try taking the batteries out for 5 min,or disconnect power for 5min.
To clear it out.
Then re input all your times days and temps,

Is t stat in a cold location near a door or window?this could also override your settings,most progrmamble stats will go into override at 58.f im guessing this is not your problem.

If it continues after you reset,i would consider a new thermostat.

Adptive intelligent recovery


On the Pro4000 model you hold the 2 arrows until you go into setup mode. Then arrow up ONLY til you get to option 13. The display will read 13 and 1, press the DOWN arrow and it will read 13 and 0. This turns off Adaptive Intelligent recovery. Now hold the 2 arrows til you see the normal display screen. You are done.

I just did this with a Honeywell tech rep on the phone.
