Limits on heat pump operation
In domestic hot water operation, following hysteresis values can be
set for the heat pump operation:
# Code
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)

Description
Do not change. (default: 1)
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
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
thermostat control: This preset value is
always taken into account.
Range: 5~95 minutes (default: 30)
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: 0.5) (step:
0.5 hour).
Remark: The minimum time is 1/2 hour
even when the selected value is 0.
Additional running time for the maximum
running time depending on the outdoor
temperature [4‑02].
Range: 0~95 minutes (default: 95).
