ZUP / PUP / LAP
..... Activate the correct long-distance line function according to the installed system scheme.
ERW
........................ Aktivierung einer Heizkreiserweiterung mit zusätzlichem Wandgerät Set-MK 261.
49)
During heating operation, the temperature at the top of the pipeline buffer must be 6°C below the highest required temperature of a
heating or hot water circuit (factory setting) so that the buffer can be loaded again.
Example:
highest requirement temperature = 50°C
Start charging when the temperature falls below 44°C at the top buffer sensor.
50)
The switch-off condition for the FULL loading program is met at the long-distance line buffer when using the factory setting at 55°C at
the top buffer sensor and 45°C at the bottom buffer sensor.

The switch-off condition for the PART charging program is met when using the factory setting at 61°C at the top of the buffer.

52)
Specification of the source from which the energy for the buffer storage is obtained.
53)
With (long-distance) lines, for example, a temperature loss caused by the length of the line can be compensated. A setting of, for
example, 2°C loss. increases the setpoint temperature by the set value.

INFO
54)
Auto
......................... Variable control of the return temperature with active start-up relief and/or partial load limit.
Fixed
....................... Fixed regulation based on the target return temperature set under the RLT target parameter.
open
........................ Function for test or emergency operation --- Manually open the RLM bypass line.
close
........................ Function for test or emergency operation --- Manually close the RLM bypass line.
OFF
.......................... Function for test or emergency operation --- Turn off the RLM mixer manually.
55)
Specifies the difference (spread) between the boiler setpoint temperature and the boiler return temperature.
56)
Determines the minimum difference (spread) between the boiler target temperature and the boiler return temperature after reaching
100% buffer load for partial load control.
Attention: Partial load control only possible with active additional sensors (5-sensor buffer management).
57)
When the start-up relief is activated, after the boiler has started, the target return temperature increases by the set value at most, in
order to enable the target boiler temperature to be reached more quickly.
