Is this product a "low voltage" thermostat like the 7624, or would I be running the full 240V conductors to the controller?

I have it running on 110. As I understand it, it is designed to replace the manual hi/lo fan and pump switch and I use it in that capacity. According to the link in Amazon to this item, it works on "2 speed 1/3 - 1 HP motors 115V/230V" Basically it gives you thermostatic control over what was previously just a fan/pump switch. It works well.

The 120v version switches the line voltage via several relays. It can switch a two-speed motor between low and high and in the "Auto" position will switch to High when the temp rises, then (occasionally) switch back to low when it gets cool enough. Not sure it would ever shut the cooler off; it's supposed to, but ...

This gizmo replaces the standard "three light switches" used in evap cooler installations: fan off/on. Pump off/on. And fan high/low. So it is 110 volt both in controlling the units and in term of its own internal power.

It runs full voltage. Mine is 120v. It's wired like a regular inline switch. Not sure if it's rated at 240 though.

This is a relay. The relay is powered by 120VAC, but the contacts of the switch are completely isolated from that 120 VAC, so that you may run almost anything off it, including low voltage devices. I use several of these to control low voltage devices and it works fine.

You need a separate thermostat that can wire and mount to the unit or run it off a line voltage wall thermostat.. This model runs on 240volt supply. Check the website King-electric.com for useful info then you can order from Amazon. All types of these must be hard wired to supply voltage. Gives great heat, really well made.

The RTH6580WF is not 110V compatible (it can only be powered through the low-voltage "C" wire of the thermostat). The description to this product says that it accepts either 110V or low-voltage "C" wire power.

From your description it sounds like you presently have a double pole line voltage thermostat which breaks one line on each of the 240 volt loads. Since the Aube relay has only one pole, you will need two relays.

No. It is rated for 120 volt single phase. You would have to reduce the 240 volt to 120 volts.

The thermostat is designed for a line load based system such as a baseboard heater, motor, hot water heater, etc. You can use it for either 120v or 240v. I assume that your 120v relay will work just fine, it certainly should draw well under the 16 amp capacity of this thermostat.

Neither. It is digital, so its super accurate, if you set it for 70 then you get 70. Sweet! It is an inline thermostat, so it will handle 1750 watts @ 120V, and it is compatible with baseboards, convectors, and fan-forced heaters. I am so glad to get rid of my old bi-metal thermostat. By the way this Honeywell digital in-line is quiet too, you don't hear any noise at all when it switches on.

240 works much better. 120 with a plug cord cannot by electrical code be installed by an electrician. .only hard wired. If it came with a plug, he can plug it in. If it didn't, he only can hard wire it. 240 volt is available at the furnace, so he can use that to efficiently wire the humidifier. The 120 option won't boil the water quick enough to run long enough on the heat cycle unless you run the fan continuously after the heat has shut off. This unit works best by far on 240 volt.

Thermostat requires 12 volts. It could run a light with some special components.

This unit us 240V, hardwired and will not accept a remote thermostat (thermostat is integral).

These are 240 volt /30 amp requirement and your temperature control needs rated as such. If mechanical type (on/off) control, you need to have a 2 pole controller to break both hot lags from 240 v breaker.

It will run on 110AC and 12 volt battery. I tested both ways. I'm not sure where you are getting 240 volts from.

Yes. Refer to Figure 10 (on Page 6) of the manual and observe TB1 wiring Block. By connecting the AC Line in to the 240 terminal instead of the 120 terminal, the unit will operate on 240VAC.

Please google images on this connector and wire. I think the wire you are using is for 120 VAC and not 240 VAC. You should have 4 conductor (Black/Black, white, green or Black/Red, white green) 2 phase @ 240V, Neutral and Ground.

My HVAC setup is old and did not supply power (C wire) to the thermostat. I purchased a 24V transformer from now-nonexistent RadioShack to drive the thermostat. It's plugged in in my bedroom closet, and the wire is ran up to the attic and down into the wall where the thermostat is installed. Everything has been working great for 3 years so far.

It's been a while since I installed, but I think if you don't install the common wire you will have a battery operated thermostat. If you have the complete 24 volt circuit, (Common installed), batteries will be the backup, in case of AC power failure.
