Setting the Time Program for DHW Heating

H The time program for DHW heating is made up of time
phases. One time phase from 5:30 to 22:00 h for every
day of the week is set at the factory.
H Automatic mode is set at the factory for DHW heating.
This means that, in standard heating mode, the DHW
is reheated to the set temperature. To ensure that hot
water is available at the start of standard heating mode,
the time phase for DHW heating begins automatically
half an hour earlier than the time phase for standard
heating mode.
H If you don't want the automatic mode, you can select
up to 4 individual time phases per day for DHW heating,
which can be the same for every day of the week or
different. Set the start and end points for each time
phase.
H When setting, bear in mind that your heating system
requires some time to heat the DHW to the required
temperature.
H In the "Extended menu", you can scan the current time
program under "Information" (see chapter "Scanning
information", "DHW" group).
