System 550
Modular Electronic Controls
Unlock System 550's Full Potential
System 550 is a modular electronic control solution that provides single or multi-stage on/off, proportional or proportional plus integral temperature, humidity and/or pressure control. It is the first of its kind to include A2L refrigerant leak sensing and mitigation functionality to ensure you are meeting A2L refrigerant regulations. Plus, always stay connected to your system with Control System Cloud, our optional two-way cloud connectivity solution.
