When you are preparing to install a line voltage thermostat, make sure your home is compatible with this type of system, as incorrect thermostat installment can lead to fire! If this thermostat is best for you, and you aren't sure which one to choose, this page contains everything you need to know, so read on! It is a type of thermostat which is normally used with baseboard or radiant heating systems. It is uncommon for one to be for cooling, although they exist. Normally line voltage thermostats use 240 volts of power, but there are occasional older line voltage models which use 120 volts. The voltage power is connected to the heater directly through the line voltage thermostat causing it to turn on or off through thick wires. These thermostats have to carry the full current drawn by the heater. These are not to be confused with low voltage thermostats or used with gas heating systems
There are two types of line voltage thermostats: single pole and double pole. Single pole systems have two wires and cannot turn off your heating system completely. A double pole system has four wires and can shut off your system completely. The double pole units have the ability to be turned until a clicking noise can be heard, so you are assured power is off. With a single pole system you can turn the heat down significantly instead of turning off the thermostat, so to speak. While most are designed with four wires as a double pole unit, some offer the option of 2-wire or 4-wire application.
Mechanical line voltage thermostats work through bimetallic strips that bend with the rise and fall of temperature. When the bimetallic element heats up, the current will switch off your heating system, and when the element cools down, the heating system will go off. Clearly, this is not the most accurate method for temperature control, and this is where electric line voltage thermostats come in. These use thermistor sensors to do basically the same thing, but with more accuracy (thermistor coming from the words thermal and resistor). Sensing elements promise the sensing of temperatures within +/-1 degree. Try a programmable one for even more added benefits!
The Line VoltPRO series is the leading choice for this thermostat family. With features such as precise readings within one degree of accuracy, soundproofing, on/off switching, and Honeywell's classic backlit display. Honeywell has created another family of creditable thermostats, improved just for your system. The one degree temperature setpoint offers precise, absolute control, so that your system will never be inaccurate. With soundproofing, the common clicking noise is reduced, so that only a light, quiet switching noise is heard with your Line VoltPRO. The on/off switch comes with the double pole Line Volt PRO, and allows you to disconnect your heating controls when you would prefer to save energy along with money. As with other Honeywell favorites, the Line VoltPRO is above and beyond others in its large screen with backlighting. When upgrading, you do not have to settle for second best. Line voltage thermostats are available with several special features, and Honeywell has them all.
