Honeywell T834C Question

Hi
My first post and I need some help. I have a Honeywell T834C it's either a 1137 or the 2309 as my home is total electric HVAC I purchased new in1984. My question is will a Honeywell TH3110D1008 non Digital wire up with out any problems??? I am retired and do not need a expensive one that you can program. I am not sure what Heat Anticipator model I have. Has anyone else with this beige T834C swapped out to another manual thermostat that is a plug and play :-) so to speak??? It does not have to be a Honeywell just a manual one that does not need batteries etc.

The old stat did not require a common wire. The new stat will require C (common) if it does not require batteries.

Do you have any extra conductors to the existing stat?

I have Not removed the old from the wall yet. I am not sure if I have 1137 or 2309. It still works but I had to tilt it some for the mercury sealed tube to cycle with the temp needle. I think it needs to be recalbrated. I looked at where the nut for the coil. I want a new manual one that is a plug and play so to speak.

You can replace it with another round one. CT87N this does not need a C wire.

Round one? Mine is the beige retangle model, is there another one the shape as mine? I painted the house and if possible I wanted one that would cover the same spot on the wall.

Oh ok, sorry.. I didn't look into the old model off hand.. Thought it was a round one.

They still make the T843c if you want to keep the same footprint.

This is what I've found for you. I think they are getting harder to find.

Glad to help. When you do get this stat, set the heat anticipator to "hot water/High Eff."

If you already had this stat, most likely you don't have a heat pump.. But if you do in fact (provide us your model # of both indoor and outdoor unit), then you may have the wrong stat, unless you have a kit near the furnace. May I ask why you hate that word, "Heat Pump"?

I know I don't have a heat pump . standard 2 1/2 ton HVAC all electric heat and A/C it was a 2 ton and a friend that moved was A/C tech and he replaced my A coils and a bit larger Copeland compressor he had 10 years ago, pulled a vacuum for several hours and installed a new drier. No hard start kit on it yet :-) it will pull down about 25 degrees from the outside temp.

hot water term??? I did not see this term(hot water) in my service manual for my stat that shows how to re calibrate the hear antcipator. I will re read the sevice manual I found online before I joined this forum.

You'll see this in the new manual, and it will show you a chart for the heat antcipator setting for type of system. Even tho you are Electric heat, set it to Hot water/Warm air (High Efficiency) setting of .8 for better comfort and long run time.
