Conguration
Condensed programming menu
Enables the rapid conguration of the most frequently-used parameters (SP, C1, d0, d1, d4, F3, A1 and A2). Press the SET key for 3
seconds to access it.
Extended programming menu
Use the extended programming menu to congure all of the unit’s parameters in order to adapt it to installation requirements. Press the
SET key for 6 seconds to access it.
Regulation and control
Important:
• If the function of the password has been congured as a keypad block (b10=2), or as an access block to parameters (b10=1), you
will be requested to enter the access code programmed in PAS when attempting to access either of the two functions. If the entered
password is not correct, the unit will go back to showing the temperature.
• Certain parameters or menus may not be visible depending on the conguration of the rest of the parameters.
