Hi, I am looking to replace my old Honeywell dial-type thermostat with a modern, digital one. I currently have two separate thermostats; one that controls A/C, and one that controls heating. Will I encounter any problems combining the functions of the two old thermostats into one new one? Thanks for any help. Neal

You should not have any problems..it's fairly straightforward and easy if you are at all handy.
That old T87F Honeywell is more accurate than a digital..but whatever floats your boat.
Cheap new stuff isnt always what it is cracked up to be . There is a good reason they stilll sell the old round Honywell ,, They Work Good.......
hey , my old thermostat just went south onme. What would you recommend? heat only, steam radiators/baseboards. Thanks!

Hard to say. I'm not there to see how it's wired.
But, as a heating and AC professional, it's very likely that the job can be done to wire them both into one. Might take a few relays installed, though.
Get another T-87. They are nearly indestructible.
sheesh..
Or it MIGHT take just the right stat, with a RC and RH terminal, but IF you WERE a pro, (and you are not) Then you would know that...right?
I would prefer to use another T87F in that case...adjustable anticipation is really nice on those steam systems.
