7 Maintenance and service
▪ 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 until the next scheduled action. 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.
Tips about DHW tank temperature
▪ 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 (Comfort =
higher DHW tank temperature) during the night, because then
space heating demand is 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
(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.
