Hot water securing works independent from the status
of the network-connection (even at network-incidents).
With the button „Single Boost“ the hot water backup can be started
immediately once
Boost Temp Set-point temperature for hot water backup
Start Hour1: Start of boost time window 1
Stop Hour1: End of boost time window 1
Start Hour2: Start of boost time window 2
Stop Hour2: End of boost time window 2
Two boost timeframes can be defined per day. These frames may overlap.
Start hour and stop hour refer to the same calendar day. If a time window is defined over
midnight, hot water backup will not start!
If start-hour and stop-hour are identical, boost-backup starts one-time until the set-point
temperature is reached.
If the adjusted start-hour is after the stop-hour, hot water backup will not start!
Legionella Protection
To ensure drinking water hygiene, a period of time can be specified up to which an adjustable
minimum temperature must be reached again after the last time this value has been reached.
The number of days of this period is adjustable between 1 and 14. A time at which the
legionella program is to be started can be specified. The factory preset values of the days is 7,
the start time is 8 pm, the temperature is 60 °C, the legionella program is "Off".
The AC ELWA-E is then supplied with a power of 3kW.
