Program 336 - Solar system with 2 consumers and layered cylinder charging
Layered system only effective with speed control activated.
(Absolute value control system: AC N1)
Program 336: Solar pumps A1 run 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 solar pump
A2 runs if:
S1 is greater than threshold min1 and S1 is greater than S3 by the difference diff2
and S3 has not exceeded threshold max2.
The three-way valve A3 switches up if:
S5 is greater than the threshold min3 or S5 is greater than S4 by the difference diff3
and S4 has not exceeded threshold max3.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S1 > (S3 + diff2) & S1 > min1 & S3 < max2
A3 = (S5 > min3 or S5 > (S4 + diff3)) & S4 < max3
All programs +2: When S4 has reached threshold max3 the quick warm-up phase is
completed and consequently the speed control blocked
optimum efficiency.
If PSC (pump speed control) is activated, the speed level is set to the maximum level, if
control output 1 is activated; the analog level for the maximum speed is output. Control
output 2 is not changed and continues control.
All programs +4: Both solar circuits have separate switch on thresholds on S1:
The output
A1 continues to retain min1 and A2 switches with min2.
The priorities for CYL 1 and CYL 2 can be set in the parameter menu under PA. In addition,
a solar priority function can be set for this diagram in the menu
PRIOR (see “solar priorities”
for more details).
