Produal HLS 44
4-pipe Fan-Coil unit room controller with Modbus RTU communication.
HLS 44 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 thermal (PWM) actuators.
