Extra Hot Water
In all Extra hot water” functions, the temperature of the hot
water increases temporarily. The temperature is rst increased
to an adjustable level by the compressor (menu 1.5) and then
the electric heater is energized until the water temperature
reaches the stop temperature (menu 1.4).
Temporary “Extra hot water” is activated manually, whilst time
based extra hot water is activated using the settings made in the
control computer.
When:
“A” appears above the
icon, temporary extra hot water
is active.
“B” appears above the
icon, time based extra hot water
is active.
NOTE
Extra hot water” usually means that the electric heater
is activated regardless of Allow add heat setting (menu
8.2.1) and therefore increases the electrical
consumption.
“Extra hot watercan be activated in three different
ways:
1.
Periodic time based extra hot water
Interval between extra hot water operation is selected
in menu 1.7. Menu 1.8 shows when the next extra hot
water operation is due.
The increased temperature is maintained by the
electric heater for one hour.
2.
Schedule time based extra hot water
The start and stop times for the day of the week when
the extra hot water operation is required are set in the
sub menus to menu 7.4.0.
The increased temperature is maintained by the
electric heater for the selected period.
3.
Temporary extra hot water
Extra hot water operation starts when Extra hot water
button is pressed, and it is kept for 3 hours. The
operation is cancelled when the button is pressed
again during the period.
The increased temperature is maintained by the
electric heater until the period of time has expired.
NOTE
Heat pump will not start until Extra hot water
