WRZ-TTK0000-2 Johnson Controls Wireless Room Sensor

Overview

The Johnson Controls WRZ-TTK0000-2 is a wireless room temperature sensor designed to sense zone temperature and transmit wireless control data to compatible building automation systems and HVAC controllers. It features an integrated LCD display, setpoint adjustment capabilities, and a push-button interface to enable efficient, wire-free environmental management in commercial and residential indoor spaces.

Features

• Built-in LCD display allows occupants to view zone temperature and status
• Push-button setpoint adjustment buttons for warmer/cooler (+/-) or scaled adjustments from 55°F to 85°F (13°C to 29°C)
• Integrated fan speed control button
• Manual occupancy override button to request immediate comfort level adjustments and optimize energy savings
• Selectable Fahrenheit and Celsius readout options
• Utilizes direct-sequence, spread-spectrum RF technology on the 2.4 GHz ISM band
