INFORMATION
Auto emergency: By default, backup heater operation
during emergency operation is NOT allowed. This means
that when a heat pump failure occurs the user needs to
manually confirm that backup heater may operate during
emergency. If the house is unattended for longer periods,
we recommend that setting [A.5.1.2] Auto emergency
operation shall be set to Automatic.

Energy saving tips
Tips about room temperature
▪ Make sure the desired room temperature is NEVER too high, but
ALWAYS according to your actual needs. Each saved degree can
save up to 6% of heating costs.
▪ Do NOT increase the desired room temperature to speed up
space heating. The space will NOT heat up faster.
▪ When your system layout contains slow heat emitters (example:
under floor heating), avoid large fluctuation of the desired room
temperature and do NOT let the room temperature drop too low. It
will take more time and energy to heat up the room again.
▪ Use a weekly schedule for your normal space heating 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 leaving water temperature
▪ In heating mode, a lower desired leaving water temperature
results in lower energy consumption and better performance.
▪ Set the desired leaving water temperature in accordance with the
heat emitter type.
Example:
Underfloor heating is designed for
lower leaving water temperature than radiators and heat pump
convectors.
