The analog pressurisation controller panel does have a push to reset function on the flight altitude selector and if it's pushed during the climb, or if the selected altitude is never reached, it cancels the return to departure airfield function of the 'OFF SCHED DESCENT'. This isn't available on the digital controller.
Is it not your company's SOP to action the QRH for an orange light such as 'OFF SCHED DESCENT'? If it is, then look at it and match it up with the technical knowledge in the vol II. What does the QRH say? Switching to standby in the sim is poor practice since the protection of automatic pressurisation control is removed.
