Information About TR42-CO2
The TR42-CO2 is part of the Honeywell TR42 series of LCD wall modules for building automation systems. It combines an integral temperature sensor with a CO₂ concentration sensor and supports connection to compatible controllers through the Sylk bus. The CO₂ sensor measures from 0 to 2,000 ppm and uses automatic background calibration to maintain measurement performance. Its LCD interface can display sensor readings and provide temperature setpoint, fan-speed, and occupancy controls depending on the controller configuration.
Key Features:
- Temperature Sensing: Measures room temperature with an integral temperature sensor.
- CO₂ Sensing: Measures carbon dioxide concentration from 0 to 2,000 ppm.
- LCD Interface: Provides a backlit monochrome display for sensor and control information.
- Sylk Communication: Uses a two-wire Sylk bus for power and data communication.
- Setpoint Adjustment: Supports configurable temperature setpoint adjustment.
- Fan Control: Provides configurable fan-speed control through the wall-module interface.
- Automatic Calibration: Uses automatic background calibration for the CO₂ sensor.
- Wall Mounting: Designed for vertical wall installation in commercial HVAC spaces.
The TR42-CO2 delivers the reliability and precision required for room temperature and CO₂ monitoring in building automation systems.
