N/A [8-00] Minimum running time for domestic hot
water operation. During this time, space
heating/cooling is NOT allowed, even
when the target domestic hot water
temperature has been reached.
Range: 0~20 minutes (default: 5)
N/A [8-01] Maximum running time for domestic hot
water operation. Domestic hot water
heating stops even when the target
domestic hot water temperature is NOT
reached. The actual maximum running
time also depends on setting [8-04].
▪ When
thermostat control: This preset value is
only taken into account if there is a
request for space heating or cooling. If
there is NO request for space heating/
cooling, the tank is heated until heat
pump OFF temperature.
▪ When
thermostat control: This preset value is
always taken into account.
Range: 5~95 minutes (default: 30)

N/A [8-02] Anti-recycling time.
Minimum time between two cycles for
domestic hot water. The actual anti-
recycling time also depends on setting
[8-04].
Range: 0~10 hours (default: 3) (step: 1/2
hour) (only for EHBH/X).
Range: 0~10 hours (default: 0.5) (step:
1/2 hour) (only for EHVH/X).
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
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).
