The Ranco ETC is a microprocessor based temperature controller suitable for switching 120Volts at up to 16Amps for heating or cooling applications making it suitable for a wide range of applications. This is a great universal controller for any application where switching 120Volts or temperatures outside that of a normal home thermostat is required. The sensor with an 8' foot cable and instructions are included with the unit. (This is the Goldline SP-30 alternative. Goldline HVAC controllers are no longer being manufactured .) We also sell the Ranco ETC controller prewired with power cord and output cord for those who dont' want to wire their own. This is a great option for those who aren't familiar with wiring.
