Note: The heat generator minimum temperature limit operates continuously to protect the
heat generator and blocks the DHW loading pump in case of temperatures below the
set value.
CAUTION In case of DHW temperature settings above 60°C this function should not be
activated to avoid safety switch-off (in particular for heat generators with a low water
capacity).
Boiler Temperature
parallel shift: Boiler Temperature parallel shift
This function determines the default setting of the tank loading temperature
compared to the set DHW setpoint.
In case of several controllers connected via bus and several DHW circuits the tank
loading temperature depends on the highest setpoint if several tanks are loaded
simultaneously.
Switching differential: DHW Tank Switching Differential
This function determines the size of the DHW switching differential. The switching
differential affects the relevant DHW setpoint symmetrically.
Loading enabling: The current DHW temperature is lower than the DHW setpoint by half the amount of
the DHW switching differential.
Loading abort: The current DHW temperature exceeds the DHW setpoint by half the amount of the
DHW switching differential.
Extended Pump
running time: DHW-loading pump extended running time
After switching off the heat generator the tank loading pump is stopped only after a
time delay to prevent a safety switch-off in case of high temperatures. The setting
can be adjusted to the capacity of the DHW tank.
Note: Excessively long overtravel times interrupt unnecessarily the heating mode and
increase the temperature in the hot water tank.
