Enter the Eliwell EWCM 900 S. Part of the Schneider Electric family (Eliwell’s parent company), this advanced controller represents a generational leap from simple electromechanical thermostats to fully integrated, programmable digital solutions. This article explores the features, applications, and practical value of the EWCM 900 S.

It supports ON/OFF, electric, and hot gas defrost termination by temperature or time. At the end of a defrost cycle, it manages drip time and fan delay to prevent blowing water or cold air into the room before the evaporator is ready. Note: Always consult the official Eliwell EWCM 900

One of the most valuable features of the Eliwell EWCM 900 S is the TTL copy card capability. If you manage 50 cold rooms, you don't want to parameterize each manually.

The EWCM 900 S isn't just a "setpoint and differential" controller. It integrates advanced logic:
