DEVIreg™ Hot Water

DEVIreg™ Hotwater is an electronic programmable controller with 4 channels for on DIN rail mounting. Every channel can be set Individually to maintain hot water with the option to disinfect manually, or on a schedule. The channels sensors can be selected between 7 different temperature sensors including NTC 15 kOhm at 25°C. Building Management System (BMS) control is possible through the Modbus RS485 serial interface. DEVIreg™ Hotwater has been developed to give the user easy setup, control of their hot water system, along with the option to disinfect. The controller allows up to 4 channels to be operated, each capable of controlling a separate pipe system. 2 sensors have to be used to measure the temperature for each channel.
