Question: does this work on steam heating systems
Document: Free enterprise at work.
did not work well at all. had to buy a new thermostat. never again will I buy a roundheat only manual thermostat
the other one we had didnt work all the time or at least it seemed like it didnt. put this one in and have had no problems at all. easy to install and holds a true temperature.
I turn it to 60 at night then when I wake up it goes to 64, then when I leave for work I turn it off. Do I really need a fancy poorly designed hard to use console to handle this part of my life? No - so this is my answer. SIMPLIFY! !
The old Honeywell Mercury thermostats from the 1960s which came with the house were starting to malfunction. We replaced those thermostats with this. It seems to work and the temperature seems accurate. Its not a fancy dial, but it seems to serve its intended purpose.My older mother is getting up there in years and if I had switched to digital she might not be able to work the dial. So this is easy, a no brainer dial and it seems to do the job.Oh, about that battery. I did some searching and I found this answer on the internet.
I will worry about the battery issue in 10 years. The battery will not die because its only used when the thermostat is first installed or the house loses power. So the battery is rarely used by the thermostat. The battery's shelf life according to Panasonic is 10 years. So it may work a little bit longer, but the design of the battery is for a shelf life of 10 years. "The battery is used when the stat is first powered and when there is a call for heat that last for over 4 hours.
This was a white and red wire only. They are low voltage so easy to work with. The posts in the thermostat were clearly marked. I used a single, small screw driver, it took 5 minutes. It worked straight away and has since. If you *D*E*S*P*I*S*E* the new fancy programmable thermostats because they are a major P. I. T. A. to work with then this is the inexpensive answer to undo this rather unnecessary automation in your life.
I had an old thermostat in my 1971 condo. The thing didn't work well, so I needed to find another thermostat that was HEAT ONLY. I found this on Amazon and decided to take the plunge. I was not disappointed. It took me about 5 minutes to hook up to the existing wires where my old thermostat was. The instructions are clear and easy to follow. This even comes with a white backplate (not shown on the picture) that can be mounted on the back of this, in case the previous hole in the wall is not covered fully by this unit.
I replaced it with a basic Honeywell manual bi-metal coil thermostat and it only lasted about a year. Not believing it was the thermostat, I replaced the thermal generator and the wiring on the heater but it still didn't work right, I could make the heater kick on if I disconnected the thermostat from the wall and twisted it around. I bought this new one today, and it wouldn't work at all. As far as I can tell, Honeywell products are unreliable junk. I hope I can find a better thermostat made by someone other than Honeywell.
I just bought one of these from a big box store, it didn't work. I guess I should have been suspicious when there were only 2 of them on the shelf and one of the packages had already been opened. I bought the unopened one and it didn't work. This is for our vacation home which had a Honeywell digital thermostat when we bought it. That one lasted about a year then started working intermittently. Since it has to have 2 AA batteries, I thought that might be the problem  but it wasn't and since we're not there all the time, I don't want something I'm going to have to worry about having the batteries go dead in the middle of winter when we're not there.
