9.2.11 Boiler
Release below outside temp (2203)
The boiler is only put into operation if the mixed outside temperature is be
low the threshold set here. The switching difference is 0.5°C.
Full charging buffer (2208)
Under prog. no. 4810 (full charging buffer storage tank) is selected, wheth
er and when the buffer storage tank is fully charged despite automatic
generator lock. Under prog.no. 2203 it is set whether the boiler takes part
in the full charging or not.
Off: The boiler does not take part in the full charging of the buffer stor
age tank.
On: The boiler takes part in the full charging of the buffer storage tank.
For more information, see
Full charging (4810), page 102
Setpoint min (2210) andSetpoint max (2212)
As a protection function the boiler temperature setpoint can be limited be
low 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.
For more information, see
Manual control (7140), page 116
Burner running time min (2241)
Here, the period following the commissioning of the burner is selected dur
ing which the shutdown differential is increased by 50%. However, this
setting cannot guarantee that the burner remains operational for the selec
ted period.
Burner off time min (2243)
The boiler minimum pause time only takes effect between heating require
ments 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) andPump overr time after HW
(2253)
The delay times of the pumps are controlled according to heating mode or
drinking water mode.
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 HW 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 val
