<Purpose> Display of diagnosed value for overload running ratio

<Operation> Service code should be input in F06 prior to use this mode.

Input F27 and press SET key to display alternately F27 with “XXX”
(present diagnosed value for overload running ratio).
‘000’ is displayed before it accumulates 480 minutes in 8H timer.
Factory default is ‘095’ which is the fixed, except in case diagnosed
value is obtained from calculation in F20.
Press SET key to return to chamber temperature display.
