Product Description

NW21D Telecom Shelter Ivs Temperature and Humidity Environment Remote Monitoring System Free Cooling System Controller

Product Description

        NW21D temperature and humidity controller controls the work of air-condition and DC fans based on indoor and outdoor temperature, indoor humidity. Control logic is smart, simple and stable, it can help energy saving. It output a start signal for ventilation system, through relay (free dry contact), and distribute AC 220V for air-conditioner. It output alarm signal when environmental condition has abnormal or equipment has failure.
