I was getting really tired of our old Honeywell analog thermostat and
how inaccurate it had become over the years. It was very difficult to
consistently set the temperature.

So I replaced it with a Hunter "Just Right" (model 42999B) digital
electronic thermostat that cost $27. I didn't bother getting the
programmable version of the thermostat because of our unpredictable
schedule.

I took pictures of the install process and wrote up a quick guide.

Here's the guide -

I don't know if we have saved much on our power bill, but I can
definitely feel the difference in how consistent the air temperature
inside the home remains.

Thanks for the info.

I don't think I saw any Hunter thermostats at The Home Depot.
I have been trying to tell my relativse to get rid of that stupid mechanical
thermostat. A lot of digital thermostats give the option of temperature
sensing, like +- .5 drgree or 1 degree, up to 2 degrees.

I used to use a programmable thermostat. It is NOT needed in a home thats
quick to heat or cool. I can set it as I like when i'm there.
I actually bought a cheap Honneywell programmable unit for $25.
I have not tried the programming. I also consider it unique
as the sensor is attached right to the case, an I can get a cold
shot from the cooling if I rest my hand there.

My first digital thermostat was a Hunter, and that was a monster
to program. That was a $100 unit way back then. It was also a two way power
with battery backup.

I think the mechanical actually actually saves heating costs because
it does not cycle as much buy the fine tune digital will feel a lot
more comfortable and you may not have to set the temperature
as high or low.

I would still have the installed thermostat installed (White Rodgers)
but the display and the controller became unrealiable.
My Ritetemp touch screen thermostat also became unreliable.
In a sense, the mechanical thermostat IS more reliable.

Therre are various levels of temperature control. The best use
adaptive PID, but the cheap systems don't go anywhere near that.

My White Rodgers only started failing after I was hammer drilling in the same wall !
Do not subject your digital thermostat to severer vibration OR drop it !

I also think I might be able to fix it, as I think its the crystal for
the circuitry is unstable.
