Exclamation Thermostat--urgent help needed

I live in an old bunglow. Have two thermostat in the same floor, in is in the bedroom area (which has control buttons) and other is in the living room area (only temperature settings). Its a faily small floor space and I am assuming the second one using as a zoning thermostat.

First one:

Problem: They are old and I am having trouble to turn on my pc. After saveral attempt it kicked in (and sometime I even cannot turn the ac on) and then the AC turn off in couple of mins.

I have gas furnace with AC and boiler. The furnace is fairly new, ac is not. But when it turn on, it works.

Questions:
1. Can you please help me to figure out the wiring for the thermostat? I got the manual online which does not make much sense to me.

Honeywell Heating-Cooling Thermostat User Guide | ManualsOnline.com


2. Which programable thermostat whould be compatible with this?
3. For the second one, can I remove it completely from the system? If so how?
4. If not, which would be compatibale model for that?

Due to the summer, I appreciate if anyone help me urgently.

Thanks.

Mark

Welcome to the forums.

Any basic thermostat will work for you.
Are you sure it's the thermostats at fault. Everyone automatically blames the thermostat when there's a problem but they aren't always the problem. Actually from what I've found it's very rarely a defective thermostat.

Yeah... for that type of thermostat with the mercury bulb (please dispose of responsibly if you do change them!, mercury does NOT belong in a landfill) the chances that the thermostat is the problem is slim to none... ESPECIALLY if they operate the heating reliably.

Thanks guyz. As the ac is working (it worked for 24 hrs in a stretch couple of weeks back) and working every now and then, any idea what might the issue if it is not the thermostat.

The reason I was thinking to change it is to get a programmable one.

Also, please advise me if I can remove the 2nd thermostat as well.
