E2: T9 temperature set point

Here a temperature can be set which can be used in connection with menu item E19 and tem-
perature sensor T9. This is a separate sensor, which is not part of standard delivery.

E9: Operating in cold surroundings ON/OFF
Value of 0: If the inlet air temperature (T5) is colder than the value set at menu point E10, the
compressor will stop and the electrical immersion heater activated automatically when required
(P5 and temperature sensor T7). The compressor can start again if the intake air temperature
(T5) has been higher than the temperature set at menu point E10 for 30 minutes.
Value of 1: If the inlet air temperature (T5) is colder than the value set at menu point E10, the
compressor will not stop, but the electrical immersion heater is activated automatically when
