Program 611:
As with program 608, but the burner requirement (
A3
) comes from sensor
S2
.
A3 (on) = S2 < min3
A3 (off) = S2 > max3
(dominant)
Program 612:
As with program 608, but the burner requirement (
A3
) comes from
S4
and
S5
.
A3 (on) = S4 < min3
A3 (off) = S5 > max3
(dominant)
Program 613:
As with program 608, but the burner requirement (
A3
) comes from sensor
S4
.
A3 (on) = S4 < min3
A3 (off) = S4 > max3
(dominant)
All pr8:
The pump
A1
runs if:
S1
is greater than threshold
min1
and
S1
is higher than
S3
by the difference
diff1
and S3 has not exceeded threshold
max1
.
or
S1
is greater than threshold
min1
and
S1
is higher than
S4
by the difference
diff1
and
S4
has not exceeded threshold
max2.
The pump
A2
runs if:
S2
is greater than threshold
min2
and
S2
is higher than
