Program 272 - Solar power system with 2 collector panels and feed pump function
Program 272: Pump A1 runs when:
 S1 is greater than the threshold min1  and S1 is greater than S3 by the difference diff1
 and S3 has not exceeded the threshold max1.
Pump A2 runs when:
 S2 is greater than the threshold min2  and S2 is greater than S3 by the difference diff1

and S3 has not exceeded the threshold max1.
The feed pump A3 runs when:
 S5 is greater than the threshold min3  and S5 is greater than S4 by the difference diff2

and S4 has not exceeded the threshold max2.
A1 = S1 > (S3 + diff1) & S1 > min1 & S3 < max1
A2 = S2 > (S3 + diff1) & S2 > min2 & S3 < max1
A3 = S5 > (S4 + diff2) & S5 > min3 & S4 < max2
All programs +1:
If the difference between collector sensors S1 and S2 exceeds the difference diff3, the
colder collector is switched off. This prevents heat from being lost in the colder collector when
temperatures are mixed.
All programs +2:
Instead of the pumps, one pump A1 and a three-way valve A2 are used.
WARNING: This program is not intended for systems with two collector fields, since through
a three-way valve one collector field is always operated at standstill.
Note: The additional application of the priority circuit "All programs +1" is recommended.
Required settings:
max1 … limit CYL 1 S3  A1, A2
max2 … limit CYL 2 S4  A3
min1 … switch-on temp. coll.1 S1  A1
min2 … switch-on temp. coll.2 S2  A2
min3 … switch-on temp. CYL 1 S5  A3
diff1 … coll.1 S1 – CYL 1 S3  A1
… coll.2 S2 – CYL 1 S3  A2
diff2 … CYL 1 S5 – CYL 2 S4  A3
diff3 … see all programs +1
