If no hot water is used for several days and the storage temperature of the HPSU compact does not reach at least 60 °C,
for hygiene reasons (Legionella protection) it is periodically heated up to above 60 °C once.
The following setting options are available:
– [2-00] Operating interval: Day(s) of the week on which the "Legionella protection" function should be started.
– [2-01] Status: 0 = Function "Anti-legionella system" is switched off, 1 = Function "Anti-legionella system" is switched on.
– [2-02] Starting time: Starting time, the day on which the function "Anti-legionella system" is started.
– [2-03] Target value: Disinfection temperature to be reached.
– [2-04] Holding time: Length of time for which the disinfection temperature should be maintained.
NOTE:
– For colder outside temperatures (Lo_A), the value Lo_Ti must be higher that the value Hi_Ti, as hotter
water is required.
– With warmer outside temperatures (Hi_A) the value Hi_Ti must be lower that the value Lo_Ti, as less hot
water is required.
