The WRZ Series Wireless Room Sensor and WRZ-7860-0 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 room sensor and receiver.Like a network sensor, the WRZ-7860-0 Receiver is designed to communicate over a Sensor Actuator (SA) Bus interface through the Master-Slave/Token-Passing (MS/TP) BACnet® protocol with JohnsonControls® Variable Air Volume (VAV) Modular Assembly (VMA) 16 Series Controllers and Field Equipment Controllers (FECs). The receiver supplies the sensed zone temperature and humidity, temperature setpoint, and occupancy override data.In a typical application, one WRZ Series Wireless Room Sensor reports to one WRZ-7860-0 Receiver; however, up to five WRZ Series Wireless Room Sensors can be associated with a single WRZ-7860-0 Receiver. In multi-sensor applications, the receiver passes all the room sensors’ data to the controller. The VMA16 Series Controller or FEC can be configured to either average the room sensors’ temperature and humidity input, or select the highest or lowest sensed temperature and humidity for control of the target zone.The WRZ-7860-0 Receiver uses direct-sequence, spread-spectrum RF technology, and operates on the 2.4 GHz Industrial, Scientific, and Medical (ISM) band. The receiver meets the IEEE 802.15.4 standard for low-power, low-duty cycle RF transmitting systems. A WRZ-7860-0 Receiver operates as a transceiver, to create a bidirectional association with a WRZ Series Wireless Room Sensor.

Dimensions Repair InformationIf The WRZ-7860-0 Receiver fails to operate within its specifications, replace the unit. For a replacement receiver, contact the nearest JohnsonControls representative. Multiple Sensor Temperature or Humidity Averaging or High/Low SelectionEnhances zone temperature or humidity control by enabling up to five sensors to report to a single receiver, which allows the controller to average the sensors’ temperature or humidity input, or select the highest or lowest sensed temperature or humidity for control of the target zone.Compact and Easy to Install DesignReceives the sensed zone temperature and humidity, temperature setpoint, and low battery condition from the WRZ Series Wireless Room Sensor, and interfaces directly with a Metasys field controller.Simple, Field-Adjustable DIP SwitchesProvide easy commissioning, with up to 4,096 unique RF addresses.Optional, Battery-Powered WRZ-SST-120 Wireless System Survey ToolProvides wireless mobility to check for the best RF link, and to determine the optimum receiver mounting locations.High Resistance to RF Interference from Other Radio Devices or RF Noise SourcesResults from application-based frequency agility, which allows for automatically changing to a different channel to avoid RF interference and missed messages.Optional FX-ZFR18xx Series Wireless Field Bus RouterActs like a repeater to extend the operating range between the receiver and its associated sensors.Blinking Red LED Light to Indicate Firmware VersionFlashes 5 seconds after the power is applied to indicate the firmware revision. For example, firmware revision 3 is indicated by the LED flashing three times during the startup process.Table 1: Features and Benefits (Part 2 of 2)FeaturesBenefitsIMPORTANT:Use the WRZ-7860-0 Receiver only to provide an input to equipment under normal operating conditions. Where failure or malfunction of the receiver could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the receiver.IMPORTANT:The WRZ-7860-0 Receiver, used in conjunction with a WRZ Series Wireless Room Sensor in a One-to-One Wireless Room Sensing System, is not designed or intended for use in mission-critical or life/safety applications.Figure 2: WRZ-7860-0 Receiver Dimensions and Physical Features, in./mmTamper ResistantSet ScrewBack of Base toFront of Dome1-1/238FIG:wrz_7860_dmnsnsSARFStatus Light-EmittingDiodes (LEDs)RJ-12 Port for SA BusConnection (on Underside)3-5/32803-5/3280WRZ-7860-0 Receiver for One-to-One Wireless Room Sensing Systems Product Bulletin3Table 2: Accessories (Part 1 of 2)Product Code NumberProduct DescriptionWRZ-MHN0100-0Wireless Room Temperature and Humidity Sensor with PIR Occupancy Sensor, Battery Level/Signal Strength LED, and Manual Occupancy Override ButtonWRZ-MNN0100-0Wireless Room Sensor (No Temperature or Humidity Sensing) with PIR Occupancy Sensor, Battery Level/Signal Strength LED, and Manual Occupancy Override ButtonWRZ-MTB0100-0Wireless Room Temperature Sensor with PIR Occupancy Sensor, Display, Setpoint Dial Adjustment Scale: 55 to 85°F (13 to 29°C), °F/°C Button, and Manual Occupancy Override ButtonWRZ-MTJ0100-0Wireless Room Sensor with PIR Occupancy, Display, Setpoint Adjustment Buttons for Warmer/Cooler (+/-) Setpoint Adjustment or Scaled Setpoint Adjustment: 55 to 85°F (13 to 29°C), and Manual Occupancy Override ButtonWRZ-MTN0100-0Wireless Room Temperature Sensor with PIR Occupancy Sensor, Battery Level/Signal Strength LED, and Manual Occupancy Override ButtonWRZ-RMT10K-0Wireless Room Temperature Sensor for Remote 10K Temperature Probes, Display, °F/°C Button, and Manual Occupancy Override ButtonWRZ-STR0000-0(Non-NIST Certified Model)Wireless Room Temperature Sensor with Remote 3K Refrigerator/Freezer Temperature Probe, Display, °F/°C Button, and Manual Occupancy Override ButtonWRZ-STRNIST-0Wireless Room Temperature Sensor with NIST Certified Remote 3K Refrigerator/Freezer Temperature Probe, Display, °F/°C Button, and Manual Occupancy Override ButtonWRZ-THB0000-0Wireless Room Temperature and Humidity Sensor with Display, Warmer/Cooler (+/-) Setpoint Dial Adjustment or Scaled Setpoint Dial Adjustment: 55 to 85°F (13 to 29°C), °F/°C Button, Relative Humidity (RH) Button, and Manual Occupancy Override ButtonWRZ-THJ0000-0Wireless Room Temperature/Humidity Sensor with Display, Setpoint Adjustment Buttons for Warmer/Cooler (+/-) Setpoint Adjustment or Scaled Setpoint Adjustment: 55 to 85°F (13 to 29°C), °F/°C Button, Relative Humidity (RH) Button, and Manual Occupancy Override ButtonWRZ-THN0000-0Wireless Room Temperature and Humidity Sensor with Battery Level/Signal Strength LED and Manual Occupancy Override ButtonWRZ-THP0000-0Wireless Room Temperature and Humidity Sensor, Warmer/Cooler (+/-) Setpoint Dial Adjustment, °F/°C Button, Relative Humidity (RH) Button, Battery Level/Signal Strength LED, and Manual Occupancy Override ButtonWRZ-TTB0000-0Wireless Room Temperature Sensor with Display, Warmer/Cooler (+/-) Setpoint Dial Adjustment or Scaled Setpoint Dial Adjustment: 55 to 85°F (13 to 29°C), °F/°C Button, and Manual Occupancy Override ButtonWRZ-TTB0000-5 Wireless Room Temperature Sensor with Display, Setpoint Adjustment Buttons for Warmer/Cooler (+/-) Setpoint Dial Adjustment or Scaled Setpoint Dial Adjustment: 55 to 85°F (13 to 29°C), Manual Occupancy Override Button, Sealed for Sanitary Hospital UseWRZ-TTD0000-0Wireless Room Temperature Sensor with Display, Warmer/Cooler (+/-) Setpoint Dial Adjustment or Scaled Setpoint Dial Adjustment: 55 to 85°F (13 to 29°C), °F/°C Button, Fan Speed Control, and Manual Occupancy Override ButtonWRZ-TTJ0000-0Wireless Room Temperature Sensor with Display, Setpoint Adjustment Buttons for Warmer/Cooler (+/-) Setpoint Adjustment or Scaled Setpoint Adjustment: 55 to 85°F (13 to 29°C), °F/°C Button, and Manual Occupancy Override ButtonWRZ-TTK0000-0Wireless Room Temperature Sensor with Display, Setpoint Adjustment Buttons for Warmer/Cooler (+/-) Setpoint Adjustment or Scaled Setpoint Adjustment: 55 to 85°F (13 to 29°C), °F/°C Button, Fan Speed Control Button, and Manual Occupancy Override ButtonWRZ-TTP0000-0Wireless Room Temperature Sensor with Warmer/Cooler (+/-) Setpoint Dial Adjustment, Battery Level/Signal Strength LED, and Manual Occupancy Override ButtonWRZ-TTR0000-0Wireless Room Temperature Sensor with Battery Level/Signal Strength LED, Manual Occupancy Override Button, and No Setpoint AdjustmentWRZ-7860-0 Receiver for One-to-One Wireless Room Sensing Systems Product Bulletin4Note:All sensors with both a dial and a display can have either a W/C or a SCALE setpoint adjustment configuration.
