Plants without buffer or combi storage tanks: Parameter “Charging priority“ should be

set to “Absolute“, ensuring that the consumers will be switched off. If this is not

observed, the required DHW temperature might not be reached.

Plants with buffer or combi storage tanks: Parameter “Charging priority“ should be set

to “None“. If this is not observed, the heating circuits of plants using storage tanks will

be unnecessarily restricted.

Parameter “Charging priority“ has no impact on the condenser pump Q9.

setpoint is attained via solar plant, independent of the time set, the period of time will be

started again.

• Fixed weekday

The legionella function can be activated on a fixed weekday (1642). When using this

setting, heating up to the legionella setpoint takes place on the selected weekday,

independent of previous storage tank temperatures.

During the period of time the legionella function is performed, the DHW circulating

pump can be activated.

During the period of time the legionella function is carried out, there is a risk of scalding

when opening the taps.
