I installed the new thermostat and not furnace comes ON and OFF every 5 minutes - space-time - 02-20-2010
in reference to http://forums.macresource.com/read.php?1,884530
I mentioned in that thread that the new thermostat seems way more sensible to temperature changes than the old one.
I installed it today, and noticed that the furnace comes ON and turns OFF way more often than before. The default setting was 4 cycles per hour, but I think it does 6 or even 7. I changed the default setting to 3 cycles per hour, if needed I can make it 2 cycles per hour, but I still would like to know why the heat comes ON and OFF so often, almost 6 times per hour, if the thing it set to 3 cycles per hour.

Does it have a heat anticipator setting? Normally you look at the current draw of the gas or oil valve and set the anticipator to that value.

Did you buy a Honeywell?

How can you set a furnace to cycle a certain number of times per hour? It should be coming
on when the temperature drops a certain amount to make it come on. Can you change the
temperature differential on the thermometer, in other words I have mine set to come when it
drops 1 degree below my set temp. and go off when goes 1 degree above the set temp. Mine
can be set to a differential as small as a 1/2 of one degree.

The thermostat has a setting for number of heating (and also cooling) cycler per hour. The default is 4. They recommend 2 for steam or gravity, 3 for high efficiency furnaces, and so on, all the way to 6 cycles per hour for electric systems.
I guess what this does is adjust the temperature differential so that the number of cycler per hour comes close to the set value. I think it takes a while for the thermostat to learn how fast the house heats up and how fast it cools down, and then adjust the T-min (when heat comes on) and T-max (when heat turns OFF). There is no temperature differential setting on this thermostat.
What model do you have?

yes, similar to this (except a white cover)

I expected more from a virus like you. since you jumped from pigs to humans, I expect you should speak at least several non-human languages.
