SOURCE: 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.

The thermostat will not cut off the A/C until the thermometer reading gets to 76.

If there is not a heat source near/behind the thermostat which is causing the thermometer to read higher than actual room temperature, it sounds like the thermostat thermometer is out of calibration.

There are ways to calibrate it, but much to involved to go into here.

One solution is to just set the thermostat at 80, knowing that it's really set on 76.

Another solution is to replace the thermostat.

SOURCE: my honeywell central heating system turns off on

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

SOURCE: Honeywell TH8320u Vision Pro 8000 Digital keeps calling for heat

Hi,
If the thermostat is not over shooting the temperature than don't worry about it.
These thermostats are very sensitive and will turn the heat back on even before the degrees drop on the display. Often they will shut down before the display changes also. You can change the sensitivity of the thermpstat if you read the directions and change the cycles per hour to a less number. There is an installers program in there that you need to push a combiunation of buttons to get too. The instructions tell you how to do that also.

Hopefully you did not throw away the instruction manual for your t-stat.. :-)

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.

Aux heat comes on


If you turn your heat on and the temperature is set 3 degrees above what the actual temperature of the room, the auxillary heat will automatically come on. The auxillary heat is an electric heat strip that provides heat to your home while the heat pump is in defrost cycle or if there are extremely low temperatures outside. Try not to set the temperature more than 2 degrees above the actual temperature of the room. Hope this helps.

I have a Skytech 3301 for a propane stove with some thermostat problems.


Great question! It sounds to me like the Skytech's swing temp setting may be out of whack.
Here is a quick link to the product page with a link to the owner's manual at the bottom if you need: Skytech 3301 Fireplace Remote.
Below is an excerpt on how to check and modify the swing temp settings for the Skytech 3301. (I apologize if the copy/paste formats poorly).
The Thermo Mode on the transmitter operates the appliance whenever the ROOM TEMPERATURE varies a
certain number of degrees from the SET TEMPERATURE. This variation is called the "SWING" or
TEMPERATURE DIFFERENTIAL. The normal operating cycle of an appliance may be 2-4 times per hour depending on how well the room or
home is insulated from the cold or drafts. A smaller "swing number" increases the number of cycles so the room temperature is more
constant. A larger "swing number" decreases the number of cycles, which saves energy, in most cases. The factory setting for the "swing
number" is 2. This represents a temperature variation of +/- 2
0
F (1
0
C) between SET temperature and ROOM temperature, which determines
when the fireplace will be activated. The "SWING" number values are:
1=+ 1
0
F (.5
0
C), 2= + 2
0
F (1
0
C) and 3 = + 3
0
F (1.6
0
C).
SETTING THE TEMPERATURE SWING (TEMPERATURE DIFFERENTIAL)
1. To change the temperature "SWING" setting (1-3), press the TIMER/TIME and DOWN buttons
simultaneously to display the current "SWING" setting in the SET TEMP frame. The letter "S" will
display in the ROOM TEMP frame on the LCD screen.
2. Press the UP or DOWN button to change the temperature differential or "SWING" (1-3). See above
for 1-3 "SWING" temperature valves.
3. To store the "swing number press the SET button or allow 15 seconds to lapse, and the new "swing
number' will be automatically programmed.

MANUAL CHECK OF " SWING" OR TEMPERATURE DIFFERENTIAL
The operation of the factory set "THERMO SWING" can be checked by adjusting the SET TEMP 2
0
F above or below the room temperature.
This will cause the system to turn ON or OFF. Normally the system will only respond to temperature changes every two minutes. Manually
changing the SET temperature will activate the system in less than 10 seconds. IF the "SWING" is changed, then a new room temperature
differential will respond. Factory setting of "SWING" temperature is 2
0
F.

My round Honeywell T-87 on the main floor(middle) of the house has no ON/OFF switch. It controls the temp of that level of the house and even though it is set at 60, the temp is way too high and reads 74....


What you are describing is the Heat Anticipator. It is a small resistor that helps the thermostat from overshooting the set temperature by heating up and shutting off the thermostat just before your set temperature. I don't think that is related to your over heat. 14 degrees is a lot and the Heat Anticipator will only effect it 4 or 5 degrees. I would remove the thermostat and check if there is a call for heat. If so, you have a shorted wire. If not, replace the thermostat.

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.

My heat is turning on but the fan isnt working. my honeywell thermostat is showing a flame and a blinking battery, and i know nothing about this thermostat, we just moved in . Can u help?


This is not a PC problem
Symptom
Heating comes on, but sometimes it
gets too hot, sometimes too cold.
Neutral not connected
Cure
Check wiring in room thermostat. Look for a
connection to the Neutral terminal (N 2 on
the Honeywell T6060, T6160, and T6360).
Make sure that it is connected (check
continuity).
If there is no neutral available, replace with a
two-wire thermostat, e.g., CT200, CM61 or
CM67. These will also offer extra energy
savings, (Without a neutral connection, the anticipator within the room thermostat does not work,
so the temperature control reduces from ± ½ºC to ±3ºC. People can feel a six degree
temperature swing. Then, if they try to adjust the room thermostat to overcome the
problem, the temperature swings become even worse.)

Honeywell Surround HZ2200 / HZ2204 /


A link to an Adobe (Acrobat) Reader format (.pdf) owner's manual for Honeywell® (Mini Tower) SURROUND HEAT™ HEATER FAN Models HZ-2200 (charcoal) and HZ-2204 (white) is here.

Some text from the manual:

SET UP
• The Surround Heat™ Heater is designed to
disperse heat in either a 360° range or in one direction only.
• To select the desired heating mode, slide the Direction Control switch, located
on the top of the heater, to the position of your choice:
– to the right (full circle) for 360° Heating
– to the left (half circle) for forward only heating (One Direction
Heating)

OPERATING INSTRUCTIONS
Select the appropriate heat dispersion mode. (See
Set-Up instructions.)
• With the Power knob in the OFF position, plug the
heater into a polarized 120V outlet.
• Turn the Thermostat control fully clockwise to the
HIGH setting.
• Turn the heater on using the Child Resistant switch
(Power knob). To operate the switch, push down
the two sides of the Power knob while turning it
clockwise to the desired position. The power
light will illuminate. The Child Resistant switch helps
ensure that the heater can not be turned on accidentally.
• When the room reaches a comfortable temperature, slowly turn the Thermostat
control counter-clockwise until the heater goes off. This is the point at which the
Thermostat setting equals the room temperature. At this setting, the Thermostat
will automatically turn the heater on and off to maintain this selected temperature.
• Push down and turn the Power knob to OFF and unplug the heater when you
are finished using it.
