PECO Control Systems

When it comes to keeping buildings comfortable and systems running efficiently, the right controls make all the difference. PECO Control Systems has built a solid reputation in the HVACR industry by manufacturing dependable, straightforward products that get the job done, and at DM Supply Source, we're proud to carry their full lineup.
Whether you're outfitting a commercial building, maintaining a residential complex, or managing an institutional facility, PECO delivers the kind of precision and durability that professionals count on day in and day out.

What Makes PECO Stand Out?

PECO has been engineering temperature control solutions for decades, and its product line reflects that experience. Their equipment is designed with the installer and end user in mind; simple to set up, easy to operate, and built to last in real-world conditions.

Here's what you'll find in our PECO inventory:

  • PECO thermostats: Available in a wide range of configurations for commercial and light commercial applications. From basic line-voltage models to programmable options, there's a thermostat for virtually every setup.

  • PECO HVAC controls: Purpose-built control modules that integrate smoothly into existing systems, giving you reliable command over heating and cooling operations.

  • PECO HVAC sensors: Accurate sensing components that feed critical data back to your control systems, helping maintain consistent comfort levels and energy efficiency.

  • PECO control switches: Durable switching devices engineered for repeated use in demanding environments.

  • PECO temperature switches: Designed to respond to specific temperature thresholds, these switches play a key role in system protection and climate regulation.

  • PECO wall sensors: Sleek, responsive sensors that monitor room conditions and communicate with your building's control infrastructure.
