The state-of-the-art 211M control system is the cornerstone of Otis’s hydraulic elevator modernization system. It offers proven reliable operation for maximum performance.
The 211M control system is a dependable microprocessor controller, which links to components such as the motor, valve, door operator and fixtures. It can be installed easily and economically. The pre-engineered system is designed to install quickly with minimal disruption to the elevator operations. It can work in conjunction with Otis’ remote elevator monitoring system to alert building owners and Otis maintenance to problems before passengers and tenants are aware them.

The 211M system applies to hydraulic elevators for your passenger or service requirements. Hydraulic elevators are found in most low-rise buildings, up to seven stories tall.
