Configuration
Condensed programming menu
Enables the rapid configuration 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 configure 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 configured 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 configuration of the rest of the parameters.
