      A line voltage thermostat is ideal for baseboard or radiant heating systems. The thermostat's electronic temperature control allows for selectable heating and cooling modes for use in hundreds of commercial HVACR applications. Line voltage thermostats can also be used for ventilation control. Select an attic fan thermostat for ventilation control with attic ventilators, fans and dampers. Choosing a thermostat with a keypad lockout switch prevents tampering. Find the thermostat you need at Grainger.
