Am I able to adjust the 'hysteresis' of my digital thermostat?


Some thermostats allow you to change the differential value - that is how far below the heating (or above the cooling) set point before calling for heat (or cooling in the case of air conditioning). The built in 1 degree differential setting provides the most even temperature in the space at the expense of more frequent furnace firing and stopping. Many people prefer this mode as opposed to allowing wider swings in temperature for less frequent furnace firing and stopping. If you wish to change this setting, you'll need to replace the thermostat as it is not user adjustable in this model.

Honeywell thermostate will not kick off on set temperture


There's a "throttling range." The unit starts (say, in heating) one degree below setpoint and shuts off two degrees above set point.

You can change the "temp" but you can't change the throttling range.

RTH2310b thermostat not heating to temperature set, I turn it off and back on, it runs few minutes then shuts off not heating to temp set on thermostat


All thermostats have a "Differential" setting that causes the thermostat to turn off early as an energy saving feature to blow all the hot air out before the furnace fan shuts down. On some stats, there is a switch on the back for setting this and some have a programming choice for setting this time. Others have no setting but normally start the heat about 2 or 3 degrees below the set-point and shut it off 2 degrees above. In this case it would be called a 5 degree differential. Look for these as described and adjust it up 2 degrees if found. Good luck.

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.

I can not set the temprature differantial of my honeywell beutler thermostas


well back when i worked on honeywell controllers, you don't set differentials on thermostat you set the temperature and it has its own differentials like + or - 1 or 2 degrees to the set temperature they don't let you play with this setting, you set your temperature and it will maintain around that temperature you shouldn't need to change the differentials around that temperature as controller does what the heater needs to get to the temperature you require setting the differential closer to set temperature will make the unit cycle a lot more and coast you more and having it to far away can let the conditioned area start to get back out of comfortable range so they set these in factory and you shouldn't be able to change them as they are set to how it should work to wrok properly so i wouldn't change them even if you could!

Thermostat drops 5 degrees before furnace turns


If you still have the installation manual for that stat you should be allowed to program a differential as little as 1 degree.

My honeywell t-stat reaches current temp setting and furnace kicks off...but within 1 minute the t-stat drops 1 degree and the freakin furnace kicks on! This can't be right as it has never happened with...


Your differential is set to close you can go into tstat and change differential setting. Your install manual for your thermostat will tell you how you can set 1.2.3 degrees differential
