I recently bought the Pace ADS200 with the Instant SetBack tool stand, and I may have discovered a bug in the current firmware (1-4) -- or perhaps the bug is in my cerebral cortex (which is still in beta).
The full instruction manual suggests setting a temp of 350 deg F for Preset 1 (to initiate a "Manual Temperature Setback"), so that the temp can be reduced quickly without having to wait for the setback timer to elapse. So I did this, and left all other settings at their default, including the instant setback temp of 350 deg F which is triggered 30 seconds after placing the handpiece in the stand.
When I pressed the black button to select Preset 1, it correctly triggered the 350 deg temp. However, if I then placed the handpiece in the stand and let the instant setback timer trigger the setback temp after 30 seconds, the temp dropped below 350 deg and kept dropping. It eventually dropped below 200 deg, at which point I pulled the handpiece from the stand and it returned to 350 deg.
It may be that Pace's suggestion to set Preset 1 to 350 deg was intended for stations without the Instant Setback stand. Without the Instant Setback stand, the default setting will trigger the setback temp after 30 minutes of inactivity. But for some reason, manually triggering a setback temp that was the same as the instant setback temp resulted in this strange behavior.
I've returned all settings to default, since waiting 30 seconds for the setback temp to automatically trigger is not an issue. Am I misunderstanding how these settings work?
