HLS 44-CO2 is a versatile room controller for individual room temperature and VAV control applications. Controller has a built-in CO₂ sensor. The controller can be connected to any system that supports Modbus RTU protocol by using the RS-485 connection. The bus is galvanically isolated from the controller's other electronics. Controller supports 0...10 V controlled actuators and thermal (PWM) actuators.
