Question about Honeywell Programmable Thermostat Heater

Cannot set heat setting by using "hold" feature

Honeywell rectangular Model #RTH221B. It gets stuck on temperature (65 degrees). When I set it at desired temperature (67 degrees) and push hold it keeps going back to 65 degrees. I thought setting a temperature and pushing hold would overide any programming that is set.

Make sure it is not telling you room temp, some of the Honeywells, will display room temp over desired temp. check that, if it wont let you switch temp than buy a new one, if you dont have a heat pump a new cheap stat is around 20.00.

My thermostat is set on 68 degrees and it shows room temperature is 68, but the furnace still kickson, Honeywell said it has a 1 degree difference. so what's the problem then?


Yes there is a one degree tolerance, in fact my heater just kicked on and it is set to 67 and the inside temperature reads 67. It is also a Honeywell.

Adjust the temp. limit on my Model M402? Setting thermostat far below 55 degree mark, gives me 65 degrees.


Hello... may be you can set the desired temperature and later the remote control and/or the internal unit show to you the temperature of the air ... just let the air conditioning try to match your desired temperature...

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.

Trying to set temp on honeywell t-stat


I believe what your experiencing is the 75 degrees is the hold temp position...the display then reverts back to the actual room temperature...it doesn't mean the set temperature changed back to 65 degrees. Try to reprogram the thermostat schedules, and try not to use the hold function...just the temporary hold. (which is bumping the programmed temperature up or down until the next programmed period)

I just installed a honeywell 5-2 progammable thermostate.. Everything is hooked up fine and I have my days, hours wake, sleep, leave...etc all set, but when it goes on.. for example, I have it set for...


You didn't include a model number, so it's hard to know for sure - but I'll take a stab at this one. Many of these t-stats have a programmable offset to reduce "hunting". This can be as little as 1 degree or more than 2 degrees.

This means if you set the offset to 1 degree and the room temperature to about 65 degrees, the furnace will heat the room until the t-stat registers a rising temperature of 66 degrees. The furnace shuts off and will not turn on again until the t-stat registers a falling temperature of 64 degrees. The average is 65 degrees, and prevents the furnace from starting and stopping numerous times instead of just once with the 1 degree offset.

You can further reduce the number of furnace start and stops by increasing the offset to 2 degrees. This would work like this when the t-stat is set to 65 degrees and the room is cool:

Room Temp Furnace
63 On
64 On
65 On
66 On
67 On
68 Off

The room is now warm and heat or furnace is off. The room begins to cool like below:

67 Off
66 Off
65 Off
64 Off
63 Off
62 On

With a 1 degree offset, the room temperature varies +/-1 degree (about 2 degrees total). With a 2 degree offset, the temperature about varies +/ -2 degrees (about 4 degrees total).

Also, when the thermostat shut the heat off, the heat that was made is delivered to the space instead of wasted by sending outdoors - so the room will get a little warmer even though no fuel is being burned. The same holds true at the other end. When the t-stat turn heat on, fuel is burned, but there's little heat until the source has reached the optimum temperature and then the heat is delivered to the space.

I hope this helps & good luck! Pleas rate my reply - thanks!

Set manually cool mode at 67 degree and heat mode at 63 degree.
Just check practically and write here, if it's helpful.

Incorrect ambient temperature on Honeywell Model RTH221B


Check in your manual for the thermostat. By pushing a combination of buttons you can get into the advanced installer menu. From there you can make an adjustment to correct the temperature.

Housesitting. RTH111B model. I cannot keep the


That is a NONprogramable T-stat. There is no program to overide, therefore there is no need for a "hold" option. To set the temp, place the switch on the side marked

COOL
OFF
HEAT

to the desired setting, and push the up down arrows on the front until the display shows 80.

The DISPLAY will revert back to the current room temperature within a few seconds, and will keep the unit on until it reaches the desired temp.

The set temperature remains at 80, it just shows the current room temp.
