The NC203 is a full-featured intelligent controller designed for residential and commercial HVAC applications. It provides advanced features that surpass standard mechanical thermostats at a competitive price point.
Key technical specifications include 5 relays rated at 2A @ 24VDC, 8 analog inputs, and 2 analog outputs (10V @ 100mA). The operating temperature range is -30°C to 70°C, with supply voltage compatibility of 12-24 VAC/DC ±20% and a power consumption of 100mA at 12VDC.
Environmental features include an operating humidity range of 0-99% non-condensing and a high-impact plastic enclosure with a UL 94V0 flammability rating. The enclosure has an IP31 rating for protection. The unit utilizes a 10K thermistor for temperature sensing with an accuracy of ±0.5°C, contributing to a tight control accuracy of 0.5°C for a comfortable indoor environment.
This controller is designed for customizable sequences of operation, supporting FCU with modulating or on/off valves, single or 3-speed fans, pressure-independent VAV, and stage sequencers. Its robust design and comprehensive features make it suitable for various HVAC projects.
