BACnet® protocol models have been added to the Spyder® family of controllers. They offer powerful functionality and are sized for variable air volume and unitary applications. The availability of the BACnet protocol provides openness and the ability to use the controller with other devices or as standalone systems. The Sylk™ two-wire, polarity-insensitive communicating bus simplifies and speeds wiring of the powerful Zio™ LCD wall module. The manufacturer’s Adaptive Integral Algorithm control offers the most accurate control available for space control applications, according to the company. Two hundred function blocks and 220 network variables provide greater programming capabilities.
