Charge / Check Charge Notes
Introduced with AOC Software Version 2, Fall of 2014.
After initiating the Charging or Check Charge Mode from the comfort
control, the OD unit CDA enters the Control Menu and the
corresponding screen (ok to charge for the cooling test mode & ok to
check for heating test mode) appears.
Upon test initiation, the CDA will show stabilizing along with the
countdown timer from 20 to 0 minutes, then the screen immediately
changes to the appropriate screen ('OK to charge' in cooling test mode
and 'OK to check' in heating test mode). The new screen will populate
a countdown timer that counts down from 100 to 0 minutes.
The CDA reverts to the home screen when the comfort control exits test
mode.
If the technician 'adds time' to the comfort control test mode, the CDA
will remain at 0 minutes until the comfort control timer expires and
exits the test mode.
The technician has the ability to navigate through the Control Menu or
other Menu Trees to evaluate system performance or perform other
component tests during these tests.
Note: CHECK CHARGE screens not available on Cooling only units
