The M7410G (ILONA-S PI) series LON actuators are targeted for decentralized building structures. They give the installers and system managers a flexible and easy to install actuator in combination with a built in PI controller, providing the following features: – Standard network variables for ambient temperature, setpoint temperature, temperature offset or valve position ensure easiest installation and proper operation. – LonMark compliance ensures interoperability with other Honeywell or 3th party LON devices. – The combination of actuator and PI controller in one device makes it easy and cheap to establish a hydronic or chilled ceiling room control loop. – The M7410G comes in 3 different forces (90/180/300 N), and so fits the most valves being used in room and zone control. – Default configuration can be used off the shelf, or can be adapted to special needs with standard Echelon tools if desired. The actuator is both, attractive and robust in design.
