Product Description
. . . . . The WRZ-7840 Receiver for One-to-One Wireless Room Temperature Sensing Systems is designed to receive wireless Radio Frequency (RF) temperature data from WRZ-TTx Series Wireless Room Temperature Sensors and provide single zone temperature control data to specified Metasys system extended architecture digital controllers in building Heating, Ventilating, and Air Conditioning (HVAC) systems. The WRZ-TTx Sensor and WRZ-7840 Receiver combination is a functional equivalent to a network sensor, such as an NS-BTP7001-0, but eliminates communications wiring (which is usually placed inside the wall) between the sensor and receiver.
Like a network sensor, the WRZ-7840 Receiver is designed to communicate over a Sensor Actuator (SA) bus interface via Multidrop Serial Bus/Token Passing (MS/TP) BACnet® protocol with Johnson Controls Variable Air Volume (VAV) Modular Assembly (VMA) 1600 controllers and Field Equipment Controllers (FECs). The receiver supplies the sensed zone temperature, temperature setpoint, and occupancy override data.. Johnson Controls. Johnson Controls. WRZ-7840-0.
