Disable protections
The software is equipped with an "installer-on-site" mode ([A.6.D]:
Disable protections) that disables automatic operation by the unit.
# Code

the
automatically. To enable automatic
operation and the protective functions,
set Disable protections=OFF.
▪ OFF: 12 hours after the first power-on,
the unit will automatically set Disable
protections=OFF, ending "installer-on-
site" mode and enabling the protective
functions. If the installer returns to the
site, the installer has to set Disable
protections=ON manually.
Pump operation
When the pump operation function is disabled the pump will stop if
the outdoor temperature is higher than the value set by [4‑02] or if
the outdoor temperature drops below the value set by [F‑01]. When
the pump operation is enabled, the pump operation is possible at all
outdoor temperatures.
# Code
N/A [F‑00] Pump operation:
▪ 0: Disabled if outdoor temperature is
higher than [4‑02] or lower than [F‑01]
depending on heating operation mode.
▪ 1:
temperatures.
Pump speed limitation
Pump speed limitation [9‑0D] defines the maximum pump speed. In
normal conditions, the default setting should NOT be modified. The
pump speed limitation will also be overruled when delta T is
abnormal.
# Code
N/A [9‑0D] Pump speed limitation
▪ 0: No limitation.
▪ 1~4: General limitation. There is
limitation
required delta T control and comfort
are NOT guaranteed.
▪ 5~8: Limitation when no actuators.
When there is no heating output, the
pump speed limitation is applicable.
When there is heating output, the
pump speed is only determined by
delta T in relation to the required
capacity. With this limitation range,
delta T is possible and the comfort is
guaranteed.
