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

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

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: 0.5) (step:
0.5 hour).
Remark:
The minimum time is 1/2 hour
even when the selected value is 0.
N/A
