Honeywell Chronotherm III, T8600D1111, furnace/AC, clicking twice, won't turn off

[sbdivemaster]

Hi, I have an old Honeywell Chronotherm III, T8600D1111. This morning, while the heat was on, the tstat would reach temperature, then click twice real fast, and the air keeps blowing. I tried lowering the heat set point, but it still clicks twice and keeps running. I'm pretty sure the tstat is shot, and I think a replacement is in order. I have found a few places that say to go to the Honeywell VisonPRO 8000, but I don't know which model is the direct replacement.

Would the Honeywell TH8110U1003 be the correct one?

Any help is much appreciated.

For a upgrade programmable stat,that one is fine.

Arigato, Jumptrout Senpai.

Would any of the other Honeywell tstats also work? E.g. TH6110D1005 FocusPRO, TH4110D1007 PRO 5-2, or any of the others listed here:

We don't need anything really fancy, but I do like the ability to set different temperatures for different parts of the day - Wake up, away, home, sleep, etc. We don't live in an area where we would need heating and cooling on the same day, but I do like the adaptive recovery feature. I just don't know much about all the bells and whistles found on various thermostats...

They will all work.

My personal preference has nothing to do with programmable.

Too old fashioned.

I will adjust it myself.

Gives me something to do in my off time.

Agreed - what could be better than - look if I just turn this dial to a temperature thats comfortable, the furnace will come on as needed to keep the area warm enough - what more could I want !

Thank you again, Jumptrout Senpai. And thank you, Kdog Poop Daddy. I like the programmable for the summer time, so when we are not at home the AC will run at a higher temp, but cool down before we get home. When it's 100°+ (much of the summer), it really does help keep the electric bill down.

OK Got the Honeywell Pro4000 tstat - blower still going.

So, I fugured out that there is a LED blinking a code...

Starting new thread.

You can continue here.

What code?

Sounds like a stuck fan relay to me.

I thought it better to start a new thread, as it was a different problem than what I started this thread for.

I did manage to fix the problem, and the new thread is here:
