Program 896:
A1 = S4 > min1 & Heating = active
A2 = S4 > min1 & S4 > S6 + diff1 & S6 < max1
A3 =
[
(S6
à
min3/max3 & TP
Req. DHW
) or ((S4 < min2 or S4 < Set flow temp + diff2) &
(Heating = active))
]
& S4 < max2
All pr1:
Cylinder priority
A1 (+1) = only if
[
(S6 < max1) & TP
Req. DHW
]
is false
Together with „All pr2“:
A1 (+3) = only if
[
(S5 < max1) & TP
Req. DHW
]
is false
All pr2:
Separate sensors for activation and deactivation threshold of the
DHW request
A2 = S4 > min1 & S4 > S5 + diff1 & (S5 < max1)
A3 on =
{
(S6 < min3 & TP
Req. DHW
) or
[
(S4 < min2 or S4 < Set flow temp + diff2) &
Heating = active
]
}
& S4 < max2
A3 off =
{
(S5 > max3 &
[
(S4 > min2 & S4 > Set flow temp + diff2) & Heating = active
]
}
or S4 >max2
All pr4:
Like program 896, however limit
max1
at
S6
only active, if heating = active.
A2 = S4 > min1 & S4 > S6 + diff1 & (S6 < max1 & Heating = active)
All pr8:
Like program 896, however the burner request is only related to the de
-
mand of the heating circuit and the cylinder charging rather than to a comparison with the
boiler temperature.
A3 on =
[
(S6 < min3 & TP
Req. DHW
) or (Heating = active)
]
& (S4 < max2)
A3 off =
(
S6 > max3 & Heating = inactive) or S4 > max2
Time programs
are not possible for the heating circuit
A1
and the DHW request
A3
. The time
program
TP
Req. DHW
only
affects the request
A3
and
not
the charging pump.
