Program 640 - Preparation of hot water including circulation and solar power system
Only makes sense if the speed control is activated!
(Absolute value control system: AC I5, Differential control DC N35)
WARNING: Collector excess temperature limitation on output A1 is activated ex works. This
must be changed to
A3 or deactivated.
Program 640: Pump A1 runs when:
 the flow switch (FS) S6 detects flow. The nominal value DVA for the PSC speed control
(absolute value control) of pump A1 is specified for sensor S5.
The circulation pump A2 runs when:
 S3 is greater than the threshold min2  and S3 is greater than S4 by the difference diff2
 and S4 has not exceeded the threshold max2.
Solar pump A3 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.
A1 = flow switch (S6) = ON
A2 = S3 > (S4 + diff2) & S3 > min2 & S4 < max2
A3 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
All programs +1:
Circulation pump A2 is only switched on when in addition to the basic function the volume
flow switch
(FS) S6 is ON.
All programs +4: Pump A1 runs when:
 the flow switch (FS) S6 detects flow or pump A2 is switched on.
A1 = A2 or flow switch (S6) = ON
