Program 464 - Solar power system with 2 consumers and bypass function
Program 464: Pump A1 runs when:
 S1 is greater than the threshold min1  and S1 is greater than S2 by the difference diff1
 or S1 is greater than S3 by diff1
 both temperature delimiters (S2 > max1 and S3 > max2) have not been exceeded.
Feed pump A2 runs when:
 S4 is greater than the threshold min2  and S4 is greater than S2 by the difference diff2

and S2 has not exceeded the threshold max1.
The feed pump A3 runs when:
 S4 is greater than the threshold min2  and S4 is greater than S3 by the difference diff3

and S3 has not exceeded the threshold max2.
A1 = (S1 > (S2 + diff1) or S1 > (S3 + diff1)) & S1 > min1
& (S2 < max1 or S3 < max2)
A2 = S4 > (S2 + diff2) & S4 > min2 & S2 < max1
A3 = S4 > (S3 + diff3) & S4 > min2 & S3 < max2
All programs+1: Instead of both pumps A2 and A3 one pump A2 and a three-way valve A3
are deployed. Valve A3/S receives power when filling cylinder CYL 2.
Speed control via control outputs: COP 1 and COP 2 are set to the highest speed as soon
as value max1 is reached.All programs +2: Both secondary solar loops have separate
switch-on thresholds at
S4:
Output
A2 retains min2, and A3 switches at min3.
Required settings:
max1 … limit CYL 1 S2  A1, A2
max2 … limit CYL 2 S3  A1, A3
min1 … switch-on temp. coll. S1  A1
min2 … switch-on temp. ssl. S4  A2, A3
min3 … see all programs +2
diff1 … coll. S1 – CYL 1 S2  A1
… coll. S1 – CYL 2 S3  A1
diff2 … supply l. S4 – CYL 1 S2  A2
diff3 … supply l. S4 – CYL 2 S3  A3
