resistance value of the booster heater, you can set the exact heater capacity and
this will lead to more accurate energy data.

Description
Booster heater delay timer.
Start-up delay time for the booster heater when
domestic hot water mode is active.
▪ When domestic hot water mode is NOT active,
the delay time is 20 minutes.
▪ The delay time starts from booster heater ON
temperature.
▪ 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.
▪ The setting [8‑03] is only meaningful if setting
[4‑03]=1. Setting [4‑03]=0/2/3/4 limits the
booster heater automatically in relation to
heat pump operation time in domestic water
heating mode.
▪ Make sure that [8‑03] is always in relation with
the maximum running time [8‑01].
Range: 20~95 minutes
