Outdoor CO2 controllers
HVAC controllers to regulate CO2, temperature and relative humidity and they measure the ambient light level. Their IP65 enclosure is designed for outdoor or harsh-environments applications. In many situations, the integrated light sensor can be used to control the ventilation system in function of the occupancy of the space. Settings can be adjusted via Modbus RTU communication. The Sentera intelligent NDIR CO2 sensor controllers transfer the measured values to a Modbus RTU register, they have no analogue output. The controller's algorithm creates a control output based on the measured temperature and relative humidity values. This control output value is written in a separate Modbus register.
