How do I program my bestech thermostat


Even the best of technicians still read the manual. There's 1000 tstats out there, gotta read the manual. If you are configuring the tstat you must know how many stage cooling, how many stage heat, heat pump, straight cool, etc. Good Luck

The Honeywell TH811U1003 thermostat is a universal programmable thermostat that gives you electronic control of 24V AC heating and cooling systems. It also has the capability to be used on 750mV heating systems

One of the best features of this thermostat is it’s big clear backlit display. The current temperature, the set temperature and the time of day are displayed at all times. Simply touching the screen also activates the back light feature.

This thermostat has a menu programming guide the helps you through the process of setting up your schedule. You are able to select multiple days and customize the thermostat for any kind of unique schedule you may have. This thermostat also let’s you take it off the wall and still be able to program it. This lets you watch TV and program it at the same time.

There are built in backups that will hold the time for you if the power goes out. This t-stat will also update for daylight savings time. There are HOLD features that allow you to modify your program and hold it and then go back to the original.

Change reminders that are built in include the air filter, UV light, humidifier service and of course the batteries of the thermostat. The blower of you furnace can also be programmed to run extra to help increase the air quality in your home.

If you decide you want to know the outdoor temperature you can purchase an additional sensor and then hook it to you thermostat. The outdoor temperature will then be displayed on you thermostat. This feature also gives you the capability of using the sensor to monitor indoor temperatures remotely.

This thermostat will keep you very comfortable as the variation typically in temperature from set point is less than 1 degree F. The thermostat after a period of time learns the characterizes of the way the house or building heats and cools and then adjusts to get the most efficient operation of the heating or cooling system while maintaining a very close temperature tolerance.

By changing a few of the parameters in the thermostat this can be can be configured for either single stage conventional heat/cool systems or any single stage heat pump system.

Frymaster Dean Deep Fryers pilots light automatically go off


Will this heat up at all. Is it the same Model # as the one you .have some changes from the one you have for 2 years ago might have been made. check model # and make sure it is the same The light that go's out might be when the unit come up to the setting you put you Thermostat on meaning it heated up and will come back on when the temp drops and it starts to heat back up. it's that simple. if you just got this unit it should work if you turn the heating setting up . Let me know if the unit heats that is the starting point.

I have a honeywell thermostat t6360.the light stays on continuously whereas before it only came on when the heating was due to come on.now the heating doesnt come on at all.


Many thermostats have battery backup as well as the 24 volt ac. Have you replaced the batteries to see if it fixes all of your issues at once?

My bestech thermostat want go no higher than 32 and my air will not come on


Check the temp in the room with another thermomiter; compare.
Or remove the Thermostat and join the two switch wires that closes when the heat comes on. Do the same for wires that causes the fan to come on. See what happens. If fan comes on, fan is good.
I cant help any further as I am not sure if you are setting for heat or Air condition.

No heat model 44100b


First make sure that your heating system is on (gas turned on if applicable). Check the unit for any error messages. My furnace has a blinking LED for trouble-shooting. However, the typical issues for it are: blocked air inlet and burner ignite the gas (alternatively, pilot light unlit). Once, the problem has been with the circuit board but that failed in the summer. Make sure the circuit breaker is on and that the cover of the furnace is fully seated. (This can be an issue after changing the filter.)

Next change the batteries if they are low. (This model needs new batteries every 30 days or so since it doesn't use AC power.) Make sure that the thermostat is set for heat. If this is a replacement thermostat, double-check that the wires were connected to the correct spots. (You should have labeled these when the old thermostat was removed.) Tighten all of the terminal screws. Use a unbent paper clip to press the reset button on the thermostat (just below and to the right of the up/down arrows). If the furnace works and the above do not solve the problem, replace the thermostat.

The manual for the 44100b is available here: http://www.hunterfan.com/uploadedFiles/Support/Owner_Manuals/44100.pdf .

I hope this helps.

Pilot light is on,but heat won't ignite to heat the house. Put new batteries in the thermostat, no reaction.


Not much to go on but lets give it a shot. If it is a furnace, you will need to find it and open it up to see if it has a pilot light or not. Without a make and model number there is very little we can help you with.

Carrier Weathermaker SX model 58SX060-CC Blower runs all the time


Remove all power from the furnace, it is likely the brain in the furnace is need of being reset, from the battery replacement, why did you change the battery, was there an indicator telling you to change it?

Many times just removing all the power to the furnace will do the trick with a reset, if not let me know and we will go from there, but it sounds like the main brain is confused or bad, more likely confused, so try the power removed first.

Than let me know wbwill@sbcglobal.net
