Pump outside range
When the pump operation function is disabled the pump will stop if the outdoor
temperature is higher than the value set by the
Space heating off
temperature [4‑02] or if the outdoor temperature drops below the value set by
the Space cooling off temperature [F‑01]. When the pump operation is
enabled, the pump operation is possible at all outdoor temperatures.
# Code Description
[4.9] [F-00] Pump operation:
▪ 0: Disabled if outdoor temperature is higher
than [4‑02] or lower than [F‑01] depending on
heating/cooling operation mode.
▪ 1: Possible at all outdoor temperatures.
Increase around 0°C
Use this setting to compensate for possible heat losses of the building due to the
evaporation of melted ice or snow. (e.g. in cold region countries).
In heating operation, the desired leaving water temperature is locally increased
around an outdoor temperature of 0°C.This compensation can be selected when
using an absolute or a weather dependent desired temperature (see illustration
below).
