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.
