Heat generation lock
With this parameter, the heat
generation lock function is released. If
this is the case, the burner and the
boiler pump are turned off when, for
example, due to a programmed input or
a sensor of the clip-in AGU 2514, the
burner is locked from the outside or the
temperature at the sensor of the clip-in
is high enough to supply the
consumers.
Setpoints
The controlled boiler temperature
setpoint can be limited with Setpoint min
and -max. These limitations can be
considered to be a protective function
for the boiler. In normal operation,
minum limitation of the boiler
temperature is the lower limit value for
the controlled boiler temperature
setpoint, depending on the boiler´s
operating mode. In normal operation,
maximum limitation of the boiler
temperature is the upper limit value for
the controlled boiler temperature
setpoint and setpoint for the electronic
limit thermostat (TR).
The adjustment range for the minimum
and maximum setpoints is limited by the
manual mode setpoint.
Setpoint manual control
In manual control, the common flow
temperature setpoint can be set to a
fixed value.
Fan PWM heating max
(cannot be changed).
PWM signal for the maximum capacity
of the unit in heating mode (for values
for the different ratings, see table).
Fan PWM controller delay
(cannot be changed).
PWM signal for device output after the
ignition phase and before modulation
release (for values for the different
ratings, see table).
Output min
(cannot be changed).
Minimum device output in kW (for
values for the different ratings, see
table).
Output nominal
(cannot be changed).
Maximum heating output in kW (for
values for the different ratings, see
table).
Burner off time min
After switching off the burner,
reconnection is prevented for this time.
In the case of shorter cycle times the
device clocks more often, for longer
periods less frequently.
Locking time dynamic SD
(cannot be changed).
(Values for different ratings see
table).
Pump overrun time HCs.
Pumps for heating circuits, also
internal device pump, will run for this
time.
Proportional coefficient Kp DHW,
Proportional coefficient Kp HCs
(cannot be changed).
These values determine the heat-up
behaviour of the device (for values
for the different ratings, see table).
