feature to work properly. When measuring the resistance value of the booster
heater, you can set the exact heater capacity and this will lead to more accurate

Booster heater delay timer.
Start-up delay time for the booster heater when
heat pump domestic hot water mode is active
and tank operation mode is Quick, refer to
4
"10.6.2 Tank" [ 70].
▪ When heat pump domestic hot water mode is
active and tank operation mode is Quick, the
delay time is 20 minutes by default. End user
can select 3 predefined values: 10, 20, or 30
minutes, see Operation mode, refer to
"Operation mode
4
timer" [ 77].
▪ The delay time starts from the moment the
heat pump begins domestic hot water
production.
▪ By adapting the booster heater delay time
versus the maximum running time, you can find
an optimal balance between the energy
efficiency and the heat up time.
▪ If the booster heater delay time is set too high,
it might take a long time before the domestic
hot water reaches its set temperature.
Range: 5~95 minutes. If Installer set values of
[8-03] other than the 3 preset values for end
user, it will be displayed in Tank > Quick mode
timer as "set by installer". We recommend to
select one of the preset values for end user.
