Due to thermal transitions, an offset occurs between the flow sensor installed in the MLR003 and the actual temperature in the water circuit (temperature drop in the valve itself and via the valve connection/adapter to the MLR003 sensor). This offset is compensated by the automatic offset correction function in the MLR003. The correction function was determined by exact measurement of valves and determine the water temperature with an accuracy of +/- n°C.
Therefore, the device uses the following automatic offset correction:
Flow Sensor RAW Value = (1.1964 * Flow Sensor measured Value) - 3.7785
Data used to determine the correction function:
