• P12
Boiler
parameter - Servo flap SEKGS shutdown difference
The parameter is intended for setting the shutdown difference of the servo flap function, i.e. for
the shutdown difference of the combustion air supply limitation for equipped boilers (DCxxGSE,
DCxxGSP) defined by
→
P11
Boiler
parameter.
When the flue gas temperature drops by the shutdown difference, the SEKGS servo flap opens
completely again.
Factory default setting: 10 K
• P13
Boiler
parameter - Recommended flue gas temperature for BRE
The parameter allows you to set the flue gas limit temperature for automatic boilers with burner
(for pellets). If the flue gas limit temperature is exceeded for more than 1 hour, a logical alarm is
issued to alert the operator to the need to clean the boiler exchanger or change the boiler burner
setting. The boiler remains in operation.
Factory default setting: Off
INFO - Logical Alarm (message) does not affect any function of the ACD03/04 controller,
it only serves for information purposes. The alarm automatically stops when the flue gas
temperature decreases.
• P14
Boiler
parameter - Enabling of heating circuits
The parameter is intended for setting the temperature at which the operation (start-up) of the
circuits (MK1, MK2, MK3, (MK4), DHW) is enabled, when the boiler is connected without the
accumulation tank.
Factory default setting: 75 °C
CAUTION - The temperature defined by → P14
Boiler
parameter must always be set to a
higher value than the switching temperature of the DKP pump in the boiler circuit defined
by → P04
Boiler
parameter.
• P15
Boiler
parameter - Shutdown difference of enabling
The parameter is intended to set the circuit shutdown difference (MK1, MK2, MK3, (MK4),
DHW) when connecting the boiler without the accumulation tank (shutdown difference for
P14
Boiler
parameter).
Factory default setting: 2 K
INFO - When the WF boiler temperature ( → P14
Boiler
parameter) drops by the defined
shutdown difference, the operation of the circuits is prohibited.
