Honeywell TR40-H-CO2 Zio Mini Wall Module, Temp/Humidity/CO2 Sensor

Description

Honeywell TR40-H-CO2 Zio Mini Wall Module Overview

The Honeywell TR40-H-CO2 Zio Mini Wall Module is a compact, multi-parameter sensing device engineered for modern building automation and HVAC control applications. Combining temperature, relative humidity, and CO2 sensing in a single sleek enclosure, this wall module delivers the precise environmental data needed to maintain occupant comfort and optimize system efficiency. Its vertical-mount design and Sylk Bus network communication make it an ideal fit for commercial and light-industrial BAS installations.

Key Features

• Three-in-one sensing: simultaneous temperature, relative humidity, and CO2 monitoring
• Default setpoint temperature range: 55°F to 85°F for flexible comfort control
• High-accuracy temperature measurement: ±0.36°F accuracy at 77°F
• Operating humidity range: 5–95% RH, non-condensing
• Sylk Bus network communication for seamless integration with compatible Honeywell controllers
• Vertical-mount wall module design for clean, professional installations
• Compact Zio Mini form factor minimizes wall footprint

Temperature Sensing

The TR40-H-CO2 provides accurate space temperature readings with a ±0.36°F accuracy rating at 77°F, ensuring reliable data for precise HVAC control decisions. The 55°F–85°F default setpoint range covers a wide spectrum of commercial comfort applications.

Humidity Sensing

Relative humidity monitoring operates across a 5–95% RH non-condensing range, giving building automation systems the data needed to manage ventilation, dehumidification, and IAQ strategies effectively.

CO2 Sensing

Integrated CO2 sensing supports demand-controlled ventilation (DCV) strategies, helping reduce energy consumption by adjusting outdoor air intake based on actual occupancy levels — a key component of ASHRAE 62.1 compliance.

Communication & Installation

• Sylk Bus network communication protocol for plug-and-play connectivity with Honeywell BAS platforms
• Vertical wall-mount orientation for standard electrical box installations
• Sleek, low-profile Zio Mini aesthetic blends with modern commercial interiors

Applications

• Commercial office buildings
