# Code Description
N/A [8-03] Booster heater delay timer.
Only for EKHW
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
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 (default: 50).
N/A [8-04] Additional running time for the maximum
running time depending on the outdoor
temperature [4-02] or [F-01].
Range: 0~95 minutes (default: 95).
