Question about Honeywell Programmable Thermostat Heater

1 Answer

My honeywell central heating system turns off on its own. I set the room temp., the heating system reaches that temp then just turns off. The temperature drops and the system does not kick back on again to reach the temperature that I initially set. So, I have to go down to the basement and turn the switch off then on and the system kicks back on again. But I can't keep running down to the basement to keep my house warm all day and night.

Hi, Just to let you know I have repaired central Heat & Air systems for 33 years and Have seen this problem on many occasions. Lets see if I can save you so many trips.It says you have a programmable stat? On this stat and on a mechanical stat, they have what is called a heat anticipator that controls how many and how often your thermostat turns you're unit off and on and how long it cycles after the stat is satisfied. If you have ever seen under the cover of a mechanical stat, ( mercury switch type) you will see a dial with an arrow with numbers as .1, .3, .4 1.0, or .15 to 1.0 amps.Some are fixed and some are adjustable. On a digital stat, you will have to get into the program and see what the heat anticipator is set on. They come from the factory at .4, but to really find out what you'res should be it takes an amprobe to do this. The setting you need is what you're gas valve requires.I am sure I have lost you, but I am just giving you a little food for thought. If you can get into you're program and set this to .4, great. If the problem continues, your anticipator on this stat is more than likely, shorted, which would require you to buy a new stat.With a shorted anticipator, it will seem to be working like you say, but when satisfied, the temp.keeps falling until you reset power, then it fires and repeats this. Change the stat. If this is central heat and air, just follow red-rc which will have a red jumper to rh for heat, white to w, green to g=fan, and yellow or blue to y = cooling. If you have central heat only, you will find 2 wires red and white.Red to rh with jumper still installed to rc and then white to w.This is quite a long explanation, but I wanted you to know a little more then the next guy about your stat. Please let me know.
Sincerely,
Shastalaker7

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.

It's either because the thermo sensor is faulty or the location is wrong. Try setting the temp one degree above room temp and see if that works, if it does it's a location issue. The thermo should be close to the centre of the house, not near an outlet or the RA vent & not in a breezeway or other heatsink, at approx 1.5m above floor level.

You want the air to distribute through the room as evenly as possible. You don't want the air to blow down in one spot. In a room where a thermostat is located make sure the air doesn't blow toward the thermostat or this will make the unit turn off before the desired temp is reached.

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.

Cannot set heat setting by using "hold" feature


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.

Heat pump auxiliary heat does not turn on


Turn up your outside thermostat in the outside unit.
You should have about 3 degrees difference in one stage to the next. So I would change the thermosat with one that has three stages of heat.

You could possibly have an ignition problem. The controller will go into a lock-out condition if flame is not established. Turning the temperature control down and then back up may be serving to reset the control system so it tries again.
