NOTE: Factory setting: 4 m.
Temperature-controlled mode:
The speed is controlled by reference to the water temperature
in order to keep the return temperature always above a pre-set
minimum temperature.
The pump also maintains the set minimum flow, if the
temperature control were to lower the pump's flow below the set
minimum.
NOTE: Factory setting: TEMP, Tmin = 55 °C, Qmin = 1.0 m³/h.
NOTE: Recommendation: Set Tmin to 5 °C lower than the
temperature of the heat generator (unless other installation
instructions specify otherwise).
Thermal disinfection:
With thermal disinfection, the heat generator periodically heats
itself and the storage tank to a higher temperature.
After 24 hours of uninterrupted operation the pump detects this
automatically by the temperature increasing at least 5 °C above
the maximum temperature it has recorded.
During thermal disinfection, the pump runs at a slightly increased
speed.
The maximum running time for thermal disinfection is 4 h,
followed by a blocking period of 3 h in which no new start is
possible.
NOTE: If the pump is switched on or the parameters are changed,
thermal disinfection can only be detected after 24 hours of
operation. Unless the tem perature exceeds 75 °C: thermal
disinfection is always activated in that case.
Key lock (« Hold ») :
The key lock prevents unintended and unauthorised
modifications of the settings on the pump.
NOTE: Factory setting: Key lock off.
