CO/CO2/Temp Sensor & Ventilation Controller
ID：DCO-S4
The model DCO-S4 is a digital ventilation controller specifically designed to monitor carbon monoxide, temperature and carbon dioxide (optional) in an enclosed or semi-enclosed car parks and to regulate car-park ventilations according to these parameters. DCO-S4 is designed for easy installation and minimum maintenance during operation. It can be operated in stand-alone mode or by optional connection to larger building management systems via output analog signals, RS485 Modbus interface or wireless Zigbee connections.
-
• Multi-functional sensing & controlling of CO, temperature or (optional) CO2 in ambient air with programmable control settings.
• State-of-art electrochemical sensor cell to measure CO gas in parts-per-million (ppm) and NDIR technology to measure CO2.
• Precision temperature sensor.
• Saves energy costs with flexible demand controlled ventilation (DCV) strategy.
• Two relay outputs (normally open contacts) with pre-settings (user adjustable) for complex local ON/OFF and/or stage controls.
• Temperature/CO2 control and display enable or disable function selects.
• Fail-safe design with N.C. contacts during power failure.
• Built-in System Test (ST) function.
• Long CO sensor cell life with typical maintenance interval > 1 year;
• Built-in temperature compensation on CO & CO2 measurement.
• Long CO2 sensor life with built-in automatic background correction (ABC) function.
• Optional CO, CO2 & Temp analogue output signals (0~10V or 4~20mA) for connection to remote central computer and/or alarm panel.
• Optional RS485 Modbus connection or wireless Zigbee connection to the gateway.
