b) Setting the efficiency level
The device is programmed with two efficiency levels: HH (automatic) and ECO
(energy-saving). The default performance level is the HH mode. To change the
mode, after defining the voltage protection level, select and hold the "SLEEP"
mode button (6) for about 1 second. Define the required operating level by
operating the control buttons (7, 8).
After making the choice or in the event of inactivity, the system will remember
the current changes in the cache after 5 seconds.
c) Defining temperature units
The system of the device is programmed to support °C or °F. To change the
unit of operation, after defining the efficiency level, select and hold the
"SLEEP" mode button (6) for about 1 second. Define the desired temperature
unit by operating the control buttons (7, 8).
After making the choice or in the event of inactivity, the system will remember
the current changes in the cache after 5 seconds.
NOTE: If, after 1 second, the "SLEEP" mode button (6) is selected again, the
system will return to the previous setting definition, keeping the programmed
sequence: voltage protection/efficiency level/temperature unit.
3.3.5. ERROR CODES
In the event of a system malfunction, the device display will show the
appropriate error messages accompanied by an acoustic signal and the
control panel will become red.
