Always shutdown when boiler maximum setpoint
is exceeded by +
If the maximum boiler temperature setpoint is exceeded
by this value, the available heating circuit pumps and
DHW tank loading pumps are also activated for cooling
the boiler. If the current boiler temperature falls below the
boiler temperature setpoint, the boiler starts up again.
Minimum boiler temperature to enable all pumps
When the current boiler temperature reaches this value,
the buffer tank loading pump starts (hysteresis: 2°C).
Recommendation for PE1 Pellet and P4 Pellet: For
systems with a storage tank, this value should be about
20°C below the specified boiler temperature setpoint
(prevention of cold through flow!).
Minimum return temperature
Prerequisite: Return temperature control with mixing
valve
Minimum temperature of return to the boiler.
Enable return mixer only with active storage tank
pump
Prerequisite: “Variant 2 and 5” or “Variant 3”
Return mixer is controlled only when the store loading
pump is active. If the pump stops, the mixer closes the
total return / opens the bypass.
Target temperature difference, flow/return temp
Defines the desired difference between flow and return
temperature in boiler heating mode.
Return setpoint delay
Prerequisite: Maintaining outfeed through return feed
mixer
Waiting time for calculating the return temperature
setpoint adjustment. Once the specified time has passed,
the heating system temperatures are evaluated.
Return setpoint boost (output influence)
Prerequisite: Maintaining outfeed through return feed
mixer
This parameter determines how heavily the deviation of
the actual boiler temperature from the boiler temperature
setpoint is weighted.
Return feed min. difference at 100% output
Prerequisite: Maintaining outfeed through return feed
mixer
Minimum difference between boiler temperature setpoint
and return temperature setpoint. The temperature
difference between the boiler outfeed temperature and
boiler return temperature should not be below this value.
This parameter is applicable when the boiler is at nominal
load.
An interpolation is made between the two parameters
between partial load and nominal load.
Heating circuit overheat invariable mode
Prerequisite: Variable mode activated or boiler system in
the cascade
The boiler setpoint temperature in heating mode is
increased by this value compared to the required flow
temperature.
