The mixed water temperature is limited between the minimum mixed water temperature MWT-02 and the maximum mixed water temperature MWT-03.
Depending on the P-band MWT-05, the integral action time MWT-06 and the calculated water temperature setpoint, the control signal varies from 0...100% as shown in the next figure.
Fig. 8. Mixed water temperature control
In order to allow an accurate measuring of the mixed water temperature, the heating circuit pump will start one minute (fixed time) before the internal temperature control is released.
