Program 320 – Layered cylinder and charging pump
Only practical with speed control activated!
(Absolute value control: mode „Normal“ and sensor input S1)
Program 320: 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:
• S5 exceeds the threshold min2 , • or, if S5 falls below min2 , S5 is greater than S4 by the
difference diff2
• and S4 has not exceeded the threshold max2 .
The charging pump A3 runs, if:
• S6 exceeds the threshold min3 • and S6 is greater than S2 by the difference diff3
• and S2 has not exceeded the threshold max3 .
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = (S5 > min2 or S5 > (S4 + diff2)) & S4 < max2
A3 = S6 > (S2 + diff3) & S6 > min3 & S2 < max3
All pr1: If S4 has reached the threshold max2 , the rapid warm-up phase is complet -
ed 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.
All pr8 (independent charging pump A3 ): charging pump A3 runs, if:
• S6 exceeds the threshold min3 • and S6 is greater than S3 by the difference diff3
• and S3 has not exceeded the threshold max3 .
A3 = S6 > (S3 + diff3) & S6 > min3 & S3 < max3
