If case constant mixed water temperature control, the mixed water temperature setpoint depends on the:
The mixed water temperature setpoint is calculated according to the formula:
Mixed Water Temp Setpoint = Setpoint Time Schedule +/- CPA
where CPA is the control point adjustment set with the wall modules setpoint potentiometer.
For constant mixed water temperature control, you should set the heating curve slope to "0".
Attention:
Even if you set the heating curve slope = 0, the heating circuit will adapt to the optimal heating curve.
In this case you have to the disable the heating curve adaptation setting parameter HCA-04 = 0 – no adaptation.
