Program 496 - 1 consumer and 3 feed pump functions
Program 496: Solar pump A1 runs 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 feed pump A2 runs when:
 S3 is greater than the threshold min2  and S3 is greater than S2 by the difference diff2
 and S2 has not exceeded the threshold max2.
The feed pump A3 runs when:
 S4 is greater than the threshold min3  and S4 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 = S3 > (S2 + diff2) & S3 > min2 & S2 < max2
A3 = S4 > (S2 + diff3) & S4 > min3 & S2 < max3
Required settings:
max1 … limit TK S2  A1
max2 … limit TK S2  A2
max3 … limit TK S2  A3
min1 … switch-on temp. coll. S1  A1
min2 … switch-on t. heat source S3  A2
min3 … switch-on temp. boiler S4  A3
diff1 … coll. S1 – TK S2  A1
diff2 … heat source S3 – TK S2  A2
diff3 … boiler S4 – TK S2  A3
