EWC Controls has built a truly innovative, plug-n-play 4 wire communicating zone system for any application. The UT-3000’s design allows the zoning system to “Talk” to the equipment and thermostats to reduce labor time and optimize performance. This “Talk” feature allows the system to auto-configure itself without installer programing or setting dip switches. The highly advanced UT-3000 is compatible with all communicating HVAC systems that are built on the ClimateTalk™ open protocol. The UT-3000, 3 zone system and expandable up to 5 zones, will also work with non-communicating 2 heat / 1 cool or 1 heat / 1 cool systems. This Hybrid design allows for maximum flexibility with one zone panel. The UT-3000 produces a true proportional signal to control BTU capacity during operation. The output signal for the system is based on how many zones are calling and the temperature of the supply air. Based on these readings this unique feature will allow an ECM motor operating on the ClimateTalk™ protocol to function at it's lowest possible Cfm output, reducing the need for a by-pass damper to control static pressure. Any multi-stage or modulating hi-efficiency HVAC system that functions in ClimateTalk™ mode, will be operated in a manner that maximizes temperature control and minimizes blower speed and reduces by-pass function. By monitoring the Supply Air temperature the UT-3000 will stage the HVAC equipment to optimize the comfort level while reducing energy consumption. Based on the demand for heating or cooling, i.e. how many zones are calling, how far out of range the supply air is from set point and the type of thermostats installed, the UT-3000 will produce the required amount of supply air to satisfy the demand. The flexibility of the UT-3000 allows the installer to change that demand level based on the customers expectations of the staging function. The Supply Air Sensor feature is a constant monitoring device that sends vital data back to the UT-3000 in order for the system to function efficiently. Adjustable target set-points on the supply air sensor allow staging to occur in shorter or longer increments, as well as, allow system capacity to increase or decrease based on the target set-points. The adjustable set points allow for greater flexibility for all operating conditions giving the installer the ability to maximize energy savings and comfort.
