Use a weekly schedule for your normal space heating or cooling
needs. If necessary, you can easily deviate from the schedule:
For shorter periods: You can overrule the scheduled room
temperature. Example: When you have a party, or when
you are leaving for a couple of hours.
For longer periods: You can use the holiday mode.
Example: When you stay at home during your holiday, or
when you go away during your holiday.
Tips about DHW tank temperature
Make sure the number (available hot water for x persons) on the
DHW tank temperature home page is NOT higher than your
actual needs.
Use a weekly schedule for your normal domestic hot water
needs (only in scheduled mode).
Program to heat up the DHW tank to a preset value
(Storage comfort = higher DHW tank temperature) during
the night, because then space heating demand is lower and
electric tariffs may be lower.
If heating up the DHW tank once at night is not sufficient,
program to additionally heat up the DHW tank to a preset
value (Storage eco = lower DHW tank temperature) during
the day.
Make sure the desired DHW tank temperature is NOT too high.
Example: After installation, lower the DHW tank temperature
daily by 1°C and check if you still have enough hot water.
Program to turn ON the domestic hot water pump only during
periods of the day when instant hot water is necessary.
Example: In the morning and evening.
