The MSR eco is designed to provide complete control for refrigeration systems with up to 4 respective 8 stages, while
serving as a central unit for up to 64 cold storage controllers. When used in conjunction with front end devices such
as the SMZ-5140 or Web-Gateway , the MSR eco becomes fully capable of control from a remote location, as well
as message communication, (see example below):
