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 values were determined by exact measurement of valves and determine the water temperature with an accuracy of +/- n°C.
The temperature control circuit input value is therefore the flow sensor value corrected by the respective offset.
