Outdoor VOC controllers
HVAC controllers to regulate air quality, temperature and relative humidity and to measure the ambient light level. Their IP65 enclosure is intended for outdoor or harsh-environment applications. In many situations, the measurement of the ambient light level can be used to control the ventilation system based on the occupancy of the space. Settings can be adjusted via Modbus RTU communication. The Sentera VOC outdoor 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.
