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.

N/A [F‑00]
Pump speed limitation
Pump speed limitation main zone [9‑0E] and pump speed limitation additional zone
[9‑0D] define the maximum pump speed. In normal conditions, the default setting
should NOT be modified. The pump speed limitation will be overruled when the
flow rate is in the range of the minimum flow (error 7H).

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,

Pump operation:
▪ 0: Disabled if outdoor temperature is higher
than [4‑02] or lower than [F‑01] depending on

Pump speed limitation main zone
▪ 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 (default: 6): 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.
