Program 144 – Solar system with layered cylinder charging
Layered systems are only practical if the speed control is activated
(Absolute value control system: Mode „Normal“ and sensor input S1)
Program 144: The solar pumps A1 run, if:
• S1 exceeds 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 upwards if:
• S3 exceeds the threshold min2 • or, if S3 falls below min2 , S3 is greater than S4 by the
difference diff2
• and S4 has not exceeded the threshold max2 .
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = (S3 > min2 or S3 > (S4 + diff2)) & S4 < max2
Program 145:
If S4 has reached the threshold max2 , the rapid warm-up phase is completed and the speed
control is blocked, which achieves optimal efficiency.
If Control Output A4 is activated, the analogue level for maximum speed will be output. Con
-
trol Output A5 is not affected and continues regulating.
