the thermostat will have two wire tails or connection points that are marked either "L1"and "L2" or "Line" ,the black and white wires from the breaker box or fuse panel hook to them. the other connections marked "T1" and "T2" or "Load" hook to the wall heater. don't forget the bare wire (the ground) in case the heater develops a short, it goes from the power source ,through the thermostat box, to the green screw on the heating fixture.

∙ 13y agoIf you are looking to isolate the voltage from your hot water tank instead of letting the built in thermostat control the temperature, you need to intercept the wire coming from the breaker to the water tank. Shut off the two pole 20 amp breaker. Disconnect the tank from the supply voltage and connect these wires to the top two terminals of your double pole switch. From the bottom of the switch reconnect the hot water tank. You now have the ability to disconnect you hot water tank from the house distribution any time that you want.

What is the difference between a single pole breaker and a double pole breaker?
Courtesy of Ace Hardware - I found it on their site · What is the difference between a double pole and a single pole thermostat?Single pole thermostats breaks only one side of the power line to your heater and cannot be turned off. Therefore, power is continuous to the heater even if it is not running. The control knob will have a low temperature setting without an off position. Single pole Thermostats uses only two wires. This means that even if the temperature dial is turned all the way down, voltage is still going into the heater through one line. This may pose a hazard to anyone who might perform electrical work on the heater without realizing that the circuit was still on. You will need to turn off the power at the circuit breaker before electrical repairs can be made safely.Double pole thermostats breaks both sides of the power line; therefore all power to the heater is interrupted. This acts as a safeguard for people performing electrical work on the heater. However, to be on the safe side, you should always turn off the power at the circuit breaker, not at the thermostat, before making any electrical repairs. A double pole will uses four wires and has a off position on the thermostat.Since they are inherently safer, you should always try to use double-pole thermostats, if possible. Another advantage of a double-pole thermostat is that you can turn it completely off and the heat will not come on no matter how cold your room gets. But with a single-pole unit, the thermostat will turn the heat on even if set on the lowest setting.CHECK YOUR LOCAL CODES FOR BUILDING REQUIREMENTS IN DETERMINING IF YOU NEED A SINGLE OR DOUBLE POLE THERMOSTAT BEFORE PURCHASING OR INSTALLING. How can I determine if I have a single or double pole thermostat?Usually, you can tell the difference between a single pole and double-pole thermostat by looking at the dial. A double-pole normally has an "Off" position on the dial whereas a single-pole thermostat does not. The only sure way to tell which kind you have is to remove it from the wall and count the wires connected to it. A double-pole thermostat will have four wires that switches both hot wires whereas a single-pole thermostat will have two wires that only switches one of the hot wires. Can I use a single or double pole thermostat with a 120, 208, or 240 volt heater?Yes. Can I use 1 thermostat to control more than 1 baseboard heater?Built-in thermostats (mounted directly on baseboard) are designed for single heater use. However, it is possible to control more than 1 heater on a wall thermostat if the thermostat rating is not exceeded. Can I mount the thermostat on one side and wire the baseboard heater on the opposite side?No, the thermostat requires power from the supply wires and must be wired in conjunction with the baseboard heater. Is a built-in or a wall mount thermostat better?A built-in control is convenient when the walls are already finished. The built-in thermostat is also convenient to install. However, the wall thermostat is a more accurate way to control the room temperature, is more convenient to use, and has a broader selection of models. The use of electronic thermostats provides more accuracy and saves you money on your electric bill. Can all of the heaters in my house be controlled by one thermostat?There are many benefits to zonal heating. Zonal systems save energy by not heating unoccupied rooms and provide the ultimate in comfort by allowing occupied zones to be heated specifically to individual needs. The purpose of each zone's (room) heater is to heat that specific zone per the set point of the individual thermostat. What is the difference between a low voltage and a line voltage thermostat?Low voltage thermostats should be used when the heater load is greater than 3,800 watts such as commercial heater or central forced air systems.Line voltage thermostats should be used for zonal heat systems such as electric fan heaters, baseboard heaters and radiant heaters. What should I do if my wall thermostat feels hot to the touch?Cadet recommends you replace the thermostat. A hot thermostat indicates that it is not working efficiently; decreasing its accuracy. NOTE: A normal operating thermostat will be slightly warmer than the room temperature by 3 to 5 degrees. Can I use a wall mount thermostat to control my heater if it has an in-built thermostat?Yes, to bypass the in-built thermostat, turn the thermostat on the heater to the highest setting, then use the wall thermostat to regulate the room temperature.
Can a martin industries wall heater model w430a be repaired?
This is a 240 volt, two chimney heater (1500 watts per chimney) with a double pole thermostat. If the heater is not heating at all, indicates thermostat or electric source issue, if one element is heating and second is not, indicates one of the elements is burned out.
How to Wire a low voltage thermostat for a 220v baseboard heater?
You will need a relay with a low-voltage coil and 220v contacts rated for the current load of the baseboard heater. If you have a low-voltage transformer, see what its output is rated at (typically 24 volts or less). Then go to an electronics parts store or call some place like Digikey (phone 800-344-4539) and tell them you need (for example) a double-pole single-throw normally-open relay with a 24 volt coil and contacts rated at 30 amps at 240 volts (change these numbers to match your situation). If you do not already have a low-voltage transformer the parts store call sell you one to match the relay coil voltage (be sure to specify if you are connecting the transformer input to 120 volts or 240 volts). Then wire it up as follows: connect the transformer output (24 volts in the example above) in series with the thermostat contacts and the relay coil. Connect the 240 volt supply to the moving arms on the relay, and connect the contacts the arms touch when the relay operates to your heater. Now when the temperature drops below its setting the thermostat contacts will close and connect the relay coil to the 24 volts, the relay will operate, and the 240 volts will be connected to the heater. When the temperature rises above the thermostat's setting, its contacts open, the relay contacts open, and the heater is disconnected. Depending on where you live there may also need to be circuit breakers, protective ground wires, etc.--ask an electrician.
How do you know what the voltage of your electric baseboard heater is if there is no label on the heater?
Go to your power panel and look for two pole breakers. If there are any 20 amp two pole breakers there is a good chance that they are for the baseboard heaters. Switch this breaker off and turn your thermostat up. If the baseboard heaters do not come on and get hot then this is the supply for them. A two pole breaker is supplying 240 volts to the heaters. Most likely there will be more that one heater on the circuit. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Can you use a double pole thermostat to replace a single pole thermostat?
Answer for USA, Canada and countries running a 60 Hz supply service.A double pole thermostat is a line thermostat and not to be confused with a low voltage stat. When the heating load has 240 volts for a supply voltage, both lines from the distribution panel are supposed to disconnect when the thermostat reaches the set point temperature. A single pole thermostat is only used on a 120 volt heater an the return leg from the heater is a neutral wire.A two pole thermostat can be used on a 120 volt circuit but a single pole thermostat should not be used on a 240 volt circuit. The reason being is that on a 240 volt circuit using a single pole thermostat, one "hot" leg doesn't get isolated from the heater and is always "hot" to ground. This is a shock hazard if you are working on the heater and depending on the thermostat as a disconnect from the distribution voltage.Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What do line voltage thermostats have that low voltage thermostats don't?
Line voltage sometimes varies according to how much load there is from neighbours and other users. When the voltage is high, the water heats more quickly so that the thermostat cuts out sooner, so the amount of energy used ia about the same. <<>> It is the difference in construction of the two thermostats. A line thermostat uses a bi-metal sensor to open and close the line voltage. The room temperature fluctuation has to be greater between the stat turning on to off, as the differential setpoint can not be regulated as fine as a low voltage stat. A low voltage thermostat uses a mercury switch that is operated from a spring that senses the room temperature. Low voltage thermostats do not control the line voltage to the heater but use a remote contactor to open and close the voltage supply to the heater. There is a compensator in the low voltage stat that can be set for the contactor's coil current. This way the temperature generated by the coil of the remote contactor is nulled and the thermostat only reads the room temperature. The differential setpoint on a low voltage thermostat has a finer setting than that of a line thermostat, so a more accurate temperature is maintained.
Double pole or single pole hot water heater thermostat?
Single pole.
When the wiring is hooked directly to the 240 v heater the heater is fine 240v at heater when thermostat is installed you lose the 240 at the heater but only have 120 v to ground on each line?
It is normal to have 120 volts to ground on the supply side of the thermostat. There are two types of thermostats, a two pole and a single pole. On the two pole stat both legs of the 240 volt supply are opened. On a single pole stat only one leg of the 240 volt supply is opened. The other leg goes directly to the heater. Make sure that your thermostat is operating properly. Be it a two pole or single pole, do a continuity test to make sure that the stat is opening and closing the internal contacts. If you lose the voltage when the stat is in the line it sounds like the stat in not closing when the demand for heat is called for.
What is the difference between single pole and double pole thermostats?
A line thermostat on a 240 volt heater must open both of the supply lines that feed the heater. This is where the double pole thermostat is used. On 120 volt heaters only one hot line needs to be opened to shut the supply off from the source therefore a single pole thermostat is used.

What does a thermostat do and how does a thermostat work?
the thermostat used to control the heater and after we select the four pole switch to some number the thermostat start connect the power to the heater at the same time the heater start to heat and when we select the switch to zero position the heater not work
How do I wire a double pole thermostat in place of a single pole?
Answer for Canada, USA and countries running a 60 Hz supply service.This description is for a line voltage thermostat. It depends on what the voltage of the baseboard heater is. If it is 120 volts the thermostat will be a single pole and that is all that is required, as the neutral wire is not to be opened according to the electrical code.Now if you are replacing the thermostat and all that you have is a two pole thermostat to replace it just use one side of the two pole thermostat. Connect the voltage supply to the top and the heater load to the bottom of the thermostat.Single pole thermostats can also be used on 240 volt installations as only one leg has to be opened to stop the current flow to the heater. This is not recommended as the other leg of the 240 volt supply is still "hot" to ground and you could get a shock if you accidentally touch the other leg and ground.The proper way of wiring a 240 volt heater is to bring the two supply wires to the top of the thermostat and connect the heater load to the bottom of the thermostat.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself, on electrical circuits, equipment or appliances always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS.
Is 220V line voltage or phase voltage?
Phase, if you are referring to line, as power line from pole.
How do you wire a single pole built in thermostat to a baseboard heater while feeding power to another thermostat?
Split the feed circuit (inside a junction box) and feed the hot to both the baseboard heater with the built in thermostat AND to the 2nd thermostat. If you have any questions, contact a local, qualified electrician, heating specialist or local handyman.
Can a martin industries wall heater model w430a be repaired?
This is a 240 volt, two chimney heater (1500 watts per chimney) with a double pole thermostat. If the heater is not heating at all, indicates thermostat or electric source issue, if one element is heating and second is not, indicates one of the elements is burned out.
Is your baseboard heater using power when a single-pole thermostat is set to low?
Your thermostat is just a temperature switch. A switch just breaks the circuit to stop the current from flowing. When you set a position on the thermostat you are telling the switch when to come on and when to shut off depending on the room temperature. If it is set to low then the base board heater will not come on until the low set-point is reached. When the room warms up to above the set-point the baseboard heater will shut off. If your concern is about a 240 volt baseboard heater and just a single pole on the thermostat do not worry. Breaking one leg of a 240 volt circuit will stop the current flow and the heater will not operate.
