WRZ-TTP0000-2 Johnson Controls Wireless Room Sensor

Overview

The Johnson Controls WRZ-TTP0000-2 is a wireless, wall-mounted room temperature sensor designed for commercial and light-industrial HVAC applications. It measures ambient temperature and transmits data via radio frequency to compatible receivers or building automation systems, eliminating the need for dedicated control wiring. This model features a warmer/cooler (+/-) setpoint dial adjustment, an integrated LED status indicator, and a manual occupancy override button.

Features

• Wireless RF design allows for flexible, cable-free installation and reduces labor costs.
• Warmer/Cooler (+/-) setpoint dial adjustment for manual zone temperature offsets.
• Integrated LED indicator provides at-a-glance status for battery level, signal strength, and commissioning.
• Manual occupancy override button immediately updates the system for occupied comfort.
• Suspended sleep mode during normal operation to conserve battery life.
