How do i adjust AC temperature variance on a Honeywell TH5220D1003 thermostat


If you are talking about the difference between heating mode and cooling mode and the room setpoint, you can not change it. It comes from the factory with a 3 degree difference. In other words if you raise the heat setpoint until it is within 3 degrees of the cooling setpoint, for every degree you raise the heat setpoint the cooling will raise a degree.
About all you can do is increase the distance between the heat and cooling setpoint. To do this either lower the cooling setpoint to 3 degrees higher than the heat setpoint you want and then increase the cooling setpoint the desired setting. For example heat and cool setpoints are 67 and 70 respectively, and you want 65 and 73. Lower the cooling setpoint to 68 and then raise the cooling setpoint to 73. Now your heating will come on 3 degress lower than 68, the 65 you wanted and cooling will come on at 73. Remember, the thermostat new setpoints will turn on the cooling at 75 and turn back off at 73 and heat will turn on at 63 and turn off at 65.
You can perform the same using the heating setpoint, just have to look at it backwards. If you need to lower the difference I recommend a 8000 series thermostat. They are the most functional thermostat that Honeywell makes, be in mind they are about 3 times more expensive and many of the setting require a well trained tech to interpret and set properly.
Hope this helps.

I bought a Honeywell RTH8500 thermostat and I can't get the temperature to go down past 75 degrees


You will need the installation book that came with the thermostat. There is a way to enter into the programming of the thermostat from the home screen. From there, you will need to find what code is the temperature settings in the manual, they are usually all 3 digit numbers. Once you find the code for the setting your looking for which is the lowest temp for the thermostat, it will have a 75 to the right of it which you can set a lower number. Sorry I do not have the manual right now to just tell you exactly how, but hope this still helps!

Everyday the central air unit keeps our house at a comfortable 73 degrees. Every evening, despite the thermostat setting of 72, the house heats up to 77-79. What's the problem?


Is the sun hitting the t-stat during the day? If its a programmable unit check the programming, perhaps its set for energy sving at night

Try it with out the programming. There is no fix if the dates and times are correct. Before you call someone you are better off buying one online ($150) and changing yourself. Should not even have to do any wiring, just remove screen and put new one on old backplate. Of course you will have to redo all your run times with the new one. Likely pay that much for the service call just to hear you need a new one. Good luck.

1996 honda accord ex (six cylinder) My engine temperature gauge will go to the halfway mark and sometimes just a small way past this half point mark. It only does this in the mid to late afternoon...


if overheats,and trows water or steam,there you can think on the water pump or the thermostat,but you only have a signal problem,try replacing the tempeture sensor.

I have a set-back number on my thermostat


the easiest way with a programmable t-stat which i assume it is, is to set the temp you want then press the hold button, otherwise if it isn't held at that temp at different times of the day the t-stat will resume its programming schedule.

Temp shows 2 degrees warmer than what is was set to


sometimes the furnace does a better job than anticipated, i wouldn't worry about it, especially if the furnace shuts off.
the setpoint is the temperature you want it to be
cycle lenghts are determined by how much recovery you are requesting. for instance, in the morning when you wake up, you want the temperature to be at its setpoint. what the thermostat will do is make the furnace run a limited lengths during the recovery process.

What tempratues should be set on a honywell 4 cycle thermost during the summer months


As a general rule set your t.sat 20 degrees below outside temp. Leave at this setting 30-45 minutes. Move down until comfortable no lower than 10 degrees below outside for 30-45 minutes. Unit should cycle normally. If it runs continuously then raise the t.stat 3 or 4 degrees up. The national average is 75-78. I usually keep mine set at 80 during the day here in Georgia and 74-78 at night...
