Description
Main Controller for B.M.S, Fan-Coil applications, with pulse modulating outputs for Cool & Heat valves, with Modbus protocol.
General
The CTU4500-PM2-3S-FC-SUPER is a main controller for Fan Coil applications, suitable for B.M.S. (Building Management System), with Modbus protocol.
It has a modular, user-friendly design with various Fan Coil applications built-in, field selectable. This modularity allows you to have one main controller for different Fan Coil applications and suit it according to customer’s needs on the spot.
The CTU4500-PM2-3S-FC-SUPER also offers cost efficient capabilities, such as, occupancy sensor and fault inputs for maximum energy saving.
The CTU4500-PM2-3S-FC-SUPER is factory pre-programmed to save valued time for the installers on field programming.
