 Fault message:
 If a fault occurs:
- Fault stored in memory in case of a mains power failure
- Fault saved in fault memory
- Relay in On position
- Unit fault LED lit steady.
To disable this function:
- Simply press the + button until the maximum value of the parameter appears. Above this value, the following message appears:
- To turn off the function, simply press Enter.
- To re-enable it, simply enter a value of between 35°C and 50°C and press Enter.
19-3- Restriction to the maximum air temperature in heating mode:
This function is used to prohibit the machine operating in heating mode when the outdoor temperature rises above a configurable value.
This function is disabled if at least one circuit is being defrosted
Visible if P2 = water-to-water and reversible air-to-water when P119 ≠ 1 (Cooling only)
- This parameter can be set to between -5°C and 20°C in 1°C increments.
- Default setting: DISABLED
The unit shuts off once the outdoor temperature ≥ P225.2
The unit restarts once the temperature rises back to above P225.2 - 2K.
 Display
This limit is not managed as a fault if the machine is shut off because of it:
- Not stored in memory if a mains power failure occurs
- Fault not saved in memory
- Fault relay in Off position
- The unit fault LED is off
To disable this function:
- Simply press the + button until the maximum value of the parameter appears. Below this value, the following message appears:
- To turn off the function, simply press Enter.
- To re-enable it, simply enter a value of between -5°C and +20°C and press Enter.
19-4- Restriction to the minimum air temperature in cooling mode:
This function is used to prohibit the machine operating in cooling mode when the outdoor temperature rises above a configurable value.
Visible if P2 = Reversible Water-to-Water and Air-to-Water when P119 ≠ 2 (Heating only)
- This parameter can be set to between -20°C and 12°C in 1°C increments.
- Default setting: DISABLED
The unit shuts off once the outdoor temperature ≤ P225.3.
The unit restarts once the temperature rises back to above P225.3 + 2K.
 Display
This limit is not managed as a fault if the machine is shut off because of it:
- Not stored in memory if a mains power failure occurs
- Fault not saved in memory
- Fault relay in Off position
- The unit fault LED is off.
