HDH-M and HDH-M-N transmitters with a Modbus communication are designed to detect carbon dioxide concentration and temperature in the climate zone. The measurement values scroll on the N model display. The wanted value can be locked to view continuously. ABCLogic™ self-calibration method eliminates the possible long term drift. The controller settings, modbus settings and options' limits can be changed by using the ML-SER tool.
