[A.6.D] N/A
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 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 the flow rate is in the range of the minimum flow
(error 7H).
# Code
N/A [9‑0D]
The maximum values depend on the unit type:
Description
▪ 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.
Description
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.
Description
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.
