Is this thermostat compatible with 240v/2000w a baseboard heater? Thanks.

No, if you read the description carefully you'll read that. That info is kind of buried in the description.

This thermostat is rated for a max. of 1100watts. The triac will short with a 2000watt load.

John,The P4400 does not work with 240 volt appliances. It is designed for 115 volt and the maximum voltage is 125.See P4400 data sheet at http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000010953.pdf

No you do not need 240v. I would recomend a 20 amp 120vac line for this unit.

Sounds like a wiring fault to me (perhaps a 120V heater hooked up to 220V?). I've used this thermostat with an oil-filled heater with excellent results, and with other, non-oil-filled heaters, with no funny business of any kind.

I purchased the model TH140-28 and am using it with a hot water baseboard radiator system with a low voltage (24V) control. The user guide shows that it can also be used with a 120 to 240 VAC control. If your system is circulating hot water, this unit should work. If your system is direct resistance heat, I cannot speak to that type system since I'm not familiar with the different types of controls that it may be using.

Its easy. 240 volts in (two wires) and two wires out (to the baseboard heater).

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.

Compatible w/ voltages of 100-240vac. May need an adapter in certain countries.

No. It is not compatible unless a relay is used. This particular heater is 240 volts. It needs a thermostat that installs on either end to regulate the unit.

Usually the watts rating is on the back of the plug. If the heater rating is less than this it will work.

I am NOT an electrician but it works for a 20a 240v heater BUT, and I stress BUT....it is NOT inline with the heater....just hooked to the same switch.

If the floor radiant heat is 240 volts, like many are, I don't suggest trying to use it. If the radiant heater is 120 volts then just make sure the current draw of the heater does exceed 20 amps which is what this thermostat will handle.

It should work for a 120V floor heating system. One has to make sure that the rated wattage of the heating (resistance) coil used is not greater than the thermostat spec. I have used over a dozen of these thermostats for 240V baseboard heaters with no problems. However, I did mange to burn one up when I ganged two heaters that totaled close to the upper wattage spec, so I would include a safety margin on the upper margin spec by at least 10% (90% of the spec).

The spec on the label says 120VAC only - the plug is 120vac type, not for 240V.

The manual that comes with the unit states 110VAC or 220VAC (+ or -) 10% single phase. Thus, 10% added to 220 = 242V. If the manual is right it should be able to run on 240VAC if you system actually supplies that voltage.

Yes The relay interfaces between the 240 volt circuit and the 24 volt circuit of the thermostat.
1844617
Yes, it has built-in relay & 24volt transformer, so it allows low voltage (24v components) control of the line voltage (240v) loads... Which is the 240 v baseboard heat er(s). Fits in heater wiring compartment.
