[A.6.6]
N/A
Do you want to start a defrost operation?
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
Description
[A.6.D]
N/A
▪ ON: Automatic operation is disabled.
All protective functions are disabled. If
the user interface home pages are off,
the
unit
will
NOT
operate
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
Description
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:
Possible
at
all
outdoor
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
Description
N/A
[9‑0D]
Pump speed limitation
▪ 0: No limitation.
▪ 1~4: General limitation. There is
limitation
in
all
conditions.
The
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.
The maximum values depend on the unit type:
