f) Call the Home screen. Based on the [Temperature] window, TWO (2) possible scenarios:
1) IF now less than 30.0° C: Return NTC #3's connector to distribution board position "X3, MON-
NTC" then allow ten (10) full minutes. If a temperature problem reoccurs return to (ABOVE)
procedure number
problem is solved!
2) IF more than 30.0° C: Swap the following components (see COMPONENT LIST below) in one at a
