Totaline makes a wide range of thermostats for your home or business. A thermostat controls your heating and cooling systems from a central panel. Totaline offers thermostats with three basic configurations, each with a different set of instructions for use. If you need to reset the unit to the manufacturer's settings, just find the model that is like yours.
