Heat pump operation
#
Code
Description
N/A
[6-00]
The temperature difference determining
the heat pump ON temperature.
Range: 2°C~20°C (default: 2°C)
N/A
[6-01]
The temperature difference determining
the heat pump OFF temperature.
Range: 0°C~10°C (default: 2°C)
INFORMATION
The maximum heat pump temperature depends on the
ambient temperature. For more information, see the
operation range.
Timers for simultaneous request space and domestic hot water
operation
#
Code
Description
N/A
[8-00]
Do not change. (default: 1)
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
system
layout
=
Room
thermostat control: This preset value is
only taken into account if there is a
request for space heating. If there is
NO request for space heating, the tank
is heated until the setpoint has been
reached.
▪ When
system
layout
≠
Room
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: 0.5
hour).
Remark:
The minimum time is 1/2 hour
even when the selected value is 0.

Code
Description
N/A
[8-03]
Anti-legionella heater delay timer.
Only for EKHW
Start-up delay time for the anti-legionella
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 anti-
legionella heater ON temperature.
▪ By adapting the anti-legionella 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 anti-legionella 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
anti-legionella
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).
