Can this thermometer be used for heat only via the wires are hooked in? Also, when the battery dies, does one just throw the thermostat away?

Yes, you can replace the battery. My thermostat is the CT87N model and takes a type CR2450 battery. This battery is hidden under the circuit board and the unit snaps apart to gain access. Take care when doing so, the temp adjustment arm needs to be assembled back exactly.

The are no batteries in mine, not sure why the description says that it requires batteries. It would be better to buy the less expensive heat-only Honeywell CT87K, URL: http://www.amazon.com/Honeywell-CT87K-RoundHeat-Manual-Thermostat/dp/B000EANORW/ref=pd_sim_sbs_hi_1

This thermostat is very simple, but controls your heat and your air. However, you do need to switch it from one to the other. It is not programmable. It's the simplest you can get. No batteries required.

It cannot be used alone. It is not wireless.It does not send alerts.It is really to be used to move the temperature sensor of a professional Honeywell Thermostat to another location without moving the control panel. You can also use several of them to "average" the temperature reading in several locations.

I have this same thermometer, and I think my battery is dead, i was able to open the compartment and take it out, it says it's a GP392 battery which costs about $4. might just buy another thermometer just in case it wasn't the battery that died.

you don't notice the wires. there is an automatic safety shut off and there is a numbered temp setting system. there is no timer you can set on the model I have.

OK, first this is a thermostat, it closes relays when the temperature is right and also the fan relay. The battery only powers the display and relay when you hit temperature. Don't worry about the voltage 12, 24. the thermostat connects the + from either the air or heater to the heater wire or the ac wire or the fan. If you go to modmyrv.com they have instructions there are only a few AC and heaters they use. Sorry for the long answer but I'm an HVAC guy, and this is not rocket science.

See the comment by Gene. Note that if you have only two wires from boiler to thermostat you can't power it from the furnace so have to use battery.

t requires 2 aa batteries to store info, and it gets wired up to the back panel. The front of the thermostat can be detached from the back panel. I had my a/c guy install the unit, but it's not very hard to do it. It comes with instructions.

I don't really have an answer because I bought this for a neighbor and put it in but I did notice that it does cover air conditioning or heating and its battery operated so therefore you don't need power wires to run it just simple contacts and probably runs for a year on battery might run longer I don't know for sure but she read you some product for the price so you could either burn up with heat to hi, you could chill out too cold either one of which would be outside of comfort range

The battery in the thermostat is for the internal clock and settings memory. To use the WiFi you must power it externally. You can download the users manual from Honeywell to see the specifics.

i dont believe the thermostat can read the remote "thermostat" or remote "sensors", unless it has the 12 volt power from the 4th wire to operate that part of the system

If the batteries are dead the thermostat will not work. However the batteries last a very long time so change them on a yearly basis if you are concerned.

yes, battery is for backup only, good thermostat i had old model last for 15 years just replace newer model because i just installed central air, works graet

Sure you can. Works like a charm. Set it and alarm will beep on temp. Nice machine. The wire can over heat in the BBQ tho. Learning exp. just get new probe. And also be careful not to pull by the wire. It possibly might pull out and not work after. Pull by the solid probe! �

Yes - You are correct. The battery will overheat and it can be damaged! Try using a thermostatically controlled outlet like Farm Innovators model TC3-3545 as long as the 120V receptacle (or thermostat) in the same general area as the battery.

No, this is strictly a 110V setup. The heat is on or off. Thermostats are usually low voltage.

If you want to use the automatic setting, you'll need to run wires for the outside temperature sensor. Most of the rest of the wires should be pretty similar though.
