P34
PWM circulation pump control
0 ÷ 1
1
With P34 = 0: PWM=100% pump stopped and
PWM=0% pump at maximum operation.
With P34 = 1: PWM=100% pump at maximum
operation and PWM=0% pump stopped.
P35
Setting of default parameters (except P0, P1,
P2, P3)
0 ÷ 1
0
0 = user parameters; 1 = default parameters
P36
Display of reset shut-down and fault
0 ÷ 1
n.a.
0 = OFF; 1 = shut-downs and faults reset
