PROCEDIMENTO PER RILEVARE LA RELATIVA POSIZIONE D'APERTURA DELLA VALVOLA PER L'ACQUA CALDA E DI QUELLA PER L'ACQUA FREDDA AZIONABILE ELETTRICAMENTE DI UNA BATTERIA DI MISCELAZIONE PER SANITARI.

摘要

The closed position of a valve having a valve member that can be rotated by an electrical motor that in turn is connected to a potentiometer furnishing an output corresponding to valve position is determined by first energizing the motor so as to close the valve and monitoring the current consumption of the motor. The instantaneous current consumption of the motor is continuously or periodically compared with a set point corresponding to motor current consumption of the motor when stalled and the potentiometer output is recorded in a nonvolatile memory generally when the instantaneous motor current consumption exceeds the output so as to establish the corresponding position as the motor closed position. Then the motor is de-energized and from then on the recorded position is used as the full-closed valve position.
