The Chroma-FP-OD series of controls is a “Plug and Play” controller for freeze protection applications. When the temperature drops below the adjustable set-point, it activates the contactor energizing the heating elements. The Technician mode allows installers or technicians to adjust the parameters for customized installations using the electronic controller installed in the front panel. The Chroma-FP-OD Built-in Ground Fault interrupter allows manual reset from the front panel. Three LEDs visible through the transparent plastic cover provides information about the status of the system.
