Room controller HLS 44-SE

Room controller HLS 44-SE

HLS 44-SE is a versatile room controller for individual room temperature and VAV control applications. 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/or thermal actuators and 0…10 V controlled dampers. The fan coil fan speed can be controlled directly with a 0…10 V output, if the fan coil is equipped with EC motor. FCRY 3 relay module is needed for controlling the speed of 3-speed fans. One 0…10 V output (Y3 or Y4) can also be configured to control a 6-way valve.
