NOTICE
Manual stop. During the space heating test run the unit measures the temperature
increase. If you manually stop the test run:
- After 30min from start, the measurement will be successful.
- Before 30min from start, the measurement might be unsuccessful.
If the measurement is successful, the logic to activate the backup heater will use a
timeframe tuned to your system. If not, it will use the default timeframe (3minutes).
INFORMATION
If the outdoor temperature is outside the range of operation, the unit may NOT
operate or may NOT deliver the required capacity.

leaving water temperature (heating/cooling mode) and tank temperature
(domestic hot water mode).
To monitor the temperatures:
