CHECK LOCAL CODES FOR BUILDING REQUIREMENTS Single pole thermostats break 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. Double pole thermostats break both sides of the power line; therefore all power to the heater is interrupted. The control knob will have an “off” position.

CHECK LOCAL CODES FOR BUILDING REQUIREMENTS Single pole thermostats break only one side or leg of the power supply lines to your heater and cannot be turned “off”. Therefore, power is continuous to the heater and the heater will come on if a low temperatures exists. The control knob will have a low temperature setting without an “off” position. Double pole thermostats break both sides or legs of the power supply lines; therefore all power to the heater is interrupted. The control knob will have an “off” position if turned fully counterclockwise.
