Can I use this to replace an old mercury switch thermostat that controls just a heater? (i.e. there is no C'wire power available, just switching)

It does require a C'wire power. There are other Z-wave thermostats out there, that are battery powered and should work in your case. I have one on my upstairs HVAC by a company called 2GIG.

I think this can replace your thermostat. You didn't say if the system was electric or gas (hot water) heating but the heavy current is probably being handled by a system relay. You can download the manual and installation document from Honeywell for additional information, and/or check with a heating contractor to be sure.

This will work with any heat only application, so should be fine as long as the electric is setup for single in-line power. Keep in mind the thermostat is battery powered, so you'll need to keep that replaced. I have this in our camper and it's about 3 feet from me. I can't say that I hear the on/off solenoid. So, however loud it is, it's not enough to wake me up.

Yes. It should work just fine. This kit comes with the wire harness wired to two heaters and a thermostat. It took 5 min to install..

These 5 answers are only half correct ,you can use thermostate . THey can be wired to turn on and off with heater set to a certain temp.

It is a wire for wire replacement. However mine failed after about 10 days ( on off on off.....). It would have burned ac motor out if I hadn't been there. I have modified a home programmable control. Better temperature control and can be programed. Only down side so far is control runs its backup batteries as the control voltage supplied to the thermostat from the ac/heater is not compatible with the programmable control. See http://www.modmyrv.com/2008/07/14/rv-digital-thermostat for an example of this mod.

You will need an electrician to run power to it from the thermostat. Mine was a replacement, so I installed it myself using the existing power line.

Not that i know of, unless you can put a in line 120v. thermostat.The only way that i know of is to bring your feed ( power) to your stat. then to your heater.It's best to have it's own feed (breaker)

My old thermostat had to be switched from heat to cool. The Hunter works perfectly in this application (gas furnace plus air conditioner). If you have a complex system such as multi-stage or heat pump, I'd consult with an expert.

I experienced a power surge in my home which fried this thermostat so I just ordered the same model number thinking I could just plug it in and replace it. Come to find out it is a contractor thermostat and there is programming of some sort that has to be done so I ended up calling an HVAC person to get it working. Good luck.

I put it in a Quelet 10000 watt heater. It allows you to control this unit with a regular low voltage thermostat. The heater I bought seems to be designed to go with this relay. It took me a little bit to figure out how this was wired, but if I recall it was very simple I did this almost 2 years ago

Most likely. If you turn off the power to your existing system and pull the existing control away from the wall you should be able to see which wires it uses. Don't go just on the color of the wire look at the label on the existing thermostat. Compare this to the diagrams in the manual (http://www.luxproducts.com/support/TX1500E_ENG_Manual.pdf) and make sure you've got all the right connections.

If you're only controlling heater, then use a 2 wire heat only unit like this one:Heat Only Digital Non-Programmable Thermostat

I don't see why not. However, you will need a 240 volt circuit and have to wire that heater for 240 volt operation. The thermostat requires this voltage.

It's a relay that has a timer and thermostat connected to it. As long as you respect the load rating of the relay (thermostat), you can switch anything.

These units connect directly to the line voltage.. If your current thermostats only connect via romex type wire then these will work. If your current thermo has low voltage wiring (thin wires) then they will not work.

Yes .. You can add a thermostat.. I actually installed a heat only wall mount thermostat .. You will have to install a control transformer also... Use the thermostat to break your primary voltage.
