Piggyback Power Cord ThermostatSeveral of our single stage thermostat controllers are available with what we like to call a piggyback plug. It’s similar to a piggyback ride, but they are not the same. 😉 A piggyback plug, also known as a switch plug, is a 6 foot grounded plug-in power cord. Purchasing a piggyback plugin thermostat controller makes installation so much easier! All you need to do is plug the thermostat plug into a standard 110/120 volt outlet. After that, plug any 110/120 volt appliance, such as a heater or fan, into the female outlet on the plug of the thermostat. If you decide a different location would work better, simply unplug it, move to the desired location, and replug it back in. See how they are similar, but not the same?

Please note these units are shipped wired for heat. If you wish to use the unit for cooling, simply open the thermostat enclosure and adjust the wires.
