Program 368 - Layered cylinder and feed pump function
Layered system only effective with speed control activated.
(Absolute value control system: AC N1)
Program 368: Solar pumps A1 run when:
 S1 is greater than the threshold min1  and S1 is greater than S2 by the difference diff1

and S2 has not exceeded the threshold max1.
The three-way valve A2 switches up when:
 S5 is greater than the threshold min2  or S5 is greater than S4 by the difference diff2
 and S4 has not exceeded the threshold max2.
The feed pump A3 runs when:
 S4 is greater than the threshold min3  and S4 is greater than S3 by the difference diff3

and S3 has not exceeded the threshold max3.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = (S5 > min2 or S5 > (S4 + diff2)) & S4 < max2
A3 = S4 > (S3 + diff3) & S4 > min3 & S3 < max3
Program 369: If S4 has reached max2, the quick warm-up phase has been completed, and
the speed control is thus blocked
 optimal efficiency.
If PSC (pump speed control) is activated, the speed level is set to the maximum level, if
control output 1 is activated; the analog level for the maximum speed is output. Control
output 2 is not changed and continues control.
