4. Power up the unit, setting the main switch to the ON position;
5. Access the firmware update menu and start the procedure through the following sequence: PRG -> PSS -> PRG -> (enter installer password)
-> PRG -> USB -> UPPA -> PRG;
6. A countdown advances on the display, at the end of the procedure the word "boot" appears and the 4 LEDs light up in sequence;
7. Remove the drive from the USB port;
8. Switch the unit on by turning the main switch to the ON position.
5. SYSTEM RESOURCES
The inputs and outputs (I/O) that can be set to activate the control functions are listed below. To configure the I/O, use the installer password to
access the configuration parameters: PRG -> PSS -> PRG -> (enter installer password) -> PRG -> PAr -> PRG -> CnF .

6. EDITING DYNAMIC SET-POINT
The regulation control allows you to modify the set-point by adding an offset value depending on the outside air temperature. To use this func -
tion, modify the values of the regulation parameters, from b08 to b14, following the information in this paragraph.PRG -> PSS -> PRG -> (enter
installer password) -> PRG -> PAr -> PRG -> rE
Parameters of regulator:
• b08 = 1 to enable the dynamic set-point / b08 = 0 to disable the dynamic set-point (default)
• b09 = maximum cooling offset
•
b10
= maximum heating offset
• b11 = Cooling outdoor temperature setting
• b12 = Heating outdoor temperature setting
• b13 = Cooling temperature delta
•
b14
= Heating temperature delta
Edit the setpoint depending on the outdoor temperature:

EXAMPLE: consider that we want to obtain the following conditions in heating mode:
• set-point of 28°C with external temperature of 18°C
• set-point of 45°C with external temperature of 2°C
Set Hea = 28 e b08 = 1, while the other parameters will be calculated as follows:
• b10 = 45 – 28 = 17
• b12 = 18
