Gas energy metering (2550)
This parameter is used to switch gas energy metering on or off. The
counter values are not deleted during this process.
Important
Charging priorityAbsolute If the charging priority is not “Absolute”
and there is a requirement for heating operation at the same time
as domestic water charging, the gas energy is only taken into
consideration in the meter for the heating circuit.
Gas energy metering readj (2551)
The gradient of the linear approximation function is adapted here.
Value < 1: Leads to lower gas energy metering.
Value > 1: Leads to increased gas energy metering.
A value of 1 means there is no change compared to the approximation
function stored.
Off delay flue gas damper (2560)
The actuation of the flue damper responds to the actuation of the fan. If
the fan is no longer actuated, the flue damper is closed. In order to bridge
short downtimes and transitions in post-ventilation and/or hearth-drying,
the flue damper is switched off with a delay. This parameter is used to set
the duration of the switch-off delay.

Lead strategy (3510)
The heat generators are switched on and off acc. to the set lead strategy
taking the specified output range into account. To switch off the effect of
the output range, the limits must be set to 0% and 100% and the lead
strategy to late on, late off.
Late on, early off: Additional boilers are switched on as late as possible
(output range max) and switched back off again as soon as possible
(output range max). I.e. as few boilers as possible in operation or short
running times for additional boilers.
Late on, late off: Additional boilers are switched on as late as possible
(output range max) and switched back off again as late as possible
(output range max). I.e. as few switching on and off processes as
possible for the boilers.
Early on, late off: Additional boilers are switched on as early as possible
(output range min) and switched back off again as late as possible
(output range min). I.e. as many boilers as possible in operation or long
running times for additional boilers.
Release integral source seq (3530)
A value generated from temperature and time. The lag boiler is switched
on when the set limit is exceeded.
Reset integral source seq (3531)
The following boiler will be switched off in case of exceeding the setpoint
Restart lock (3532)
The restart lock prevents switching a switched off boiler being switched
back on again. It is only released again after the set time period has
elapsed. This prevents the boiler switching on and off too often and
achieves a stable operating condition of the system.
Switch on delay (3533)
Too frequent forward and back switching (cycles) of the boiler are avoided
by the switch-on delay and therefore a stable operating state is ensured.
