Ranco ETC Model Selector

The RANCO ETC is a microprocessor-based family of temperature controls designed to provide on/off control for commercial heating, cooling, air conditioning and refrigeration applications. With its wide temperature range, one and two stage capability, selectable heating/cooling modes and multi-voltage input, the ETC is one of the most versatile temperature controls available.

There are 10 different models of Ranco ETC Controllers to choose from. The following table summarizes the primary features that are different between the the available models. If you are unsure which model will work for you or have any additional questions please feel to Contact Us.

Relay Output Ratings - NO(NC):

One Stage (controlling heating or cooling) and Two Stage (controlling both heating and colling at the same time) have different output power limits. If the relays of the Two stage models don't satisfy your needs, you may need to use either an external relay, or two Ranco ETC Controllers since the One Stage controllers can control higher amperage. All relays are capable of switching 0 to 240 volts.
