Full charging buffer (2208)
Under prog. no. 4810 (full charging buffer storage tank) is selected,
whether and when the buffer storage tank is fully charged despite
automatic generator lock. Program no. 2208 is used to set whether the
boiler takes part in the full charging or not.
Off: The boiler does {1}not{2} take part in the full charging of the buffer
storage tank.
On: The boiler takes part in the full charging of the buffer storage tank.
Setpoint min (2210) andSetpoint max (2212)
As a protection function the boiler temperature setpoint can be limited
below by the minimum setpoint (prog.no. 2210) and above by the
maximum setpoint (prog.no. 2212).
Setpoint manual control (2214)
Temperature to which the boiler is controlled in manual control mode.
Burner running time min (2241)
Here, the period following the commissioning of the burner is selected
during which the shutdown differential is increased by 50%. However, this
setting cannot guarantee that the burner remains operational for the
selected period.
Burner off time min (2243)
The boiler minimum pause time only takes effect between heating
requirements coming following in sequence. The boiler minimum pause
time blocks the boiler for a set time.
SD burner off time (2245)
When a switching difference is exceeded,Burner off time min (prog. no.
2243) is aborted. The boiler starts despite pausing time.
Pump overrun time (2250) and Pump overr time after DHW
(2253)
The delay times of the pumps are controlled according to heating mode or
drinking water mode.
Frost prot plant boiler pump (2300)
This parameter can be used to set whether the frost protection system
should affect the boiler pump.
Off: The frost protection system does not affect the boiler pump.
On: The frost protection system affects the boiler pump.
Boiler pump on heat gen lock (2301)
Stop of boiler pump in case of activated manual heat generation lock (e.g.
via H1).
Off: Switching off not activated
On: Switching off activated
Impact heat generation lock (2305)
This parameter is used to set whether the heat generator lock should be
effective only for heating requests or also for DHW requests.
Heating mode only: Only heating requests are locked. DHW requests
are still operated.
Heating and DHW mode: All heating and DHW requests are locked.
Temp differential max (2316)
When the pump reaches the maximum speed with the setting temperature
rise nominal, the temperature difference increases via the boiler. The
value set in temperature rise maximum is not exceeded. This is achieved
by reducing the boiler setpoint to the current return temperature plus the
value shown here.
