Product Details
Controller with DC 0-10V signal for EC centrifugal impeller
IVS temperature controller, LED display, auto control two A/C and EC fan, monitor fire, flood, door, motion besides temp.. Real-time recording, and upload date via Mini USB port.
It’s wall-mounted, multi-function with small size.
It controls the work of two air-conditioners and EC fan based on indoor and outdoor temperature. Control logic is smart, simple and stable, it can help energy saving. It output a start signal for air-conditioner via relay (free dry contact), and DC 0-10V PWM signal for EC fan.
It monitor fire, door open, water in floor, motion, battery voltage, AC power off and EC fan failure besides two temp..
It also can real-time recording temp, alarm code and work status, upload date via Mini USB port.
It output alarm signal when environmental condition has abnormal or equipment has failure.
