Product Description
ETC RCT-1H-UW Wall-Mount CO2, Temperature and Humidity Sensor
Overview
The Wireless CO2 Sensor (RCT) uses wireless technology to communicate accurate indoor CO2, temperature, and relative humidity readings to compatible controllers or gateways.The RCT sensor is designed for commercial facilities where indoor environmental quality is of concern and potential savings from utilizing CO2 based demand controlled ventilation is desired. The sensor is equipped with a solar panel that harvests light energy from natural or artificial light sources. Excess energy is stored for use in periods of darkness allowing the sensor to operate for as long as 75 hours with no light. A CR2032 battery is installed for calibration purposes or to provide backup power for up to five years in continued low light applications.
The RCT incorporates Echoflex’s latest diagnostic and configuration features to ensure calibrated CO2 values, wireless range and solar harvesting capability. At the push of a button, the RCT sensor can indicate current CO2 levels via three colored LEDs. Simple button press and hold sequences can display solar energy harvesting performance and Echoflex’s Range Confirmation technology will indicate radio signal strength.
Sensor status updates are dynamically controlled driven by power management logic that determines the messaging rate to ensure consistent and timely updates. Further control logic monitors quick changes in data values and can push immediate sensor updates to linked receivers.
An on-board absolute pressure sensor provides correction for CO2 readings when at higher altitudes ensuring accuracy with each reading. CO2 calibration can be initiated manually or as an automatic self-calibration routine.
The Echoflex RCT sensor works with many gateways from common BEMS manufacturers to provide explicit, accurate, and timely monitoring of a facility’s interior spaces.
