Program 816 – Boiler circuit pump, mixer for return flow boosting
Program 816:
Boiler circuit pump
A1
is enabled, if
S1
exceeds the threshold
min1
and
S4
is
greater than
S2
by the difference
diff1
and
S2
has not exceeded the threshold
max1
.
A1 = S1 > min1 & S1 > (S2 + diff1) & S2 < max1
Program 817:
Like program 816, however with additional 10V burner request via sensors
S4
and
S2
at the control output A4.
A1 = S1 > min1 & S1 > (S2 + diff1) & S2 < max1
A4 on = S4 < min3
A4 off = S2 > max3
The menu
Technician level/Parameters
features a setting to change the control output from
inverse no
to
inverse yes
. The setting
inverse yes
has the control output generating 0 Volts,
if the threshold
min3
is underrun and 10 Volts, if the threshold
max3
is exceeded.
Program 818:
Like program 816, but with additional 10 V burner request via sensors
S4
and
S5
at the control output
A5.
A1 = S1 > min1 & S1 > (S2 + diff1) & S2 < max1
A5 on = S4 < min3
A5 off = S5 > max3
The menu
Technician level/Parameters
features a setting to change the control output from
inverse no
to
inverse yes
. The settings
inverse yes
has the control output generating 0 Volts,
if the threshold
min3
is underrun and 10 Volts, if the threshold
max3
is exceeded.
min3
... A4 on (10V)
S4
(FS = 60°C)
max3
... A4 off (0V)
S2
(FS = 75°C)
min3
... A5 on (10V)
S4
(FS = 60°C)
max3
... A5 off (0V)
S5
(FS = 75°C)
