Adjustment Control Units FIXED-POINT OR WEATHER COMPENSATION FOR HIGH/MEDIUM TEMPERATURE WITH 0-10V SETPOINT PROPORTIONAL INLET AND RTU MODBUS REMOTE MANAGEMENT OPERATION THREE SELECTABLE TYPES OF OPERATION FIXED-POINT REGULATION By means of a temperature probe, the control unit detects the fluid temperature and generates opening or closing commands for the motorised valve (not included), suitably calculated by the regulator with PID algorithm. This allows the system to maintain a constant temperature according to the setpoint value. Adjustment range -15°C to +90°C In case of power interruption,...

Adjustment Control Units FIXED-POINT OR WEATHER COMPENSATION FOR HIGH/MEDIUM TEMPERATURE WITH 0-10V SETPOINT PROPORTIONAL INLET AND RTU MODBUS REMOTE MANAGEMENT REMOTE MANAGEMENT MODBUS RTU The control unit is equipped with a MODBUS RTU interface; using the RS485 serial connection, it is possible to modify all the operating parameters, send commands to the valve and receive information on the operating status. The control units can be connected to the modern Building Management Systems (BMS). The Modbus address table can be downloaded from www.comparato.com. FLOW SENSOR EXTHERNAL PROBE ELECTRICAL...
