Automatic temperature reduction (ACE)
Unnecessary thermal loading of the melt should be avoided. The device therefore swit-
ches to standby mode at reduced temperature when the trigger has not been actuated for
a considerable time (paused operation).
In the condition as supplied the temperature is reduced by 40 °C after 30 minutes' paused
operation. The programming of the relevant parameters is described in Section 3.3.2.
Briefly actuate the trigger or the Up or Down button to quit standby mode. The device
immediately reheats to working temperature.
