Menu; Setpoint Menu; Alarm Menu [Err]; Troubleshooting - Trane Picco R32-140 User& Installer's Manual

The DOWN key is used to move to a lower menu or to decrease the value of a parameter.
In standard operation, the display shows the water outlet temperature in tenths of Celsius degrees or the alarm code if at least one is active. If
several alarms are triggered, the first one is displayed while the second one will be displayed as soon as the first one is reset. In menu mode, the
display depends on the current position.
