The Grasslin Model Digi 20E 24 Hour / 7 Day Digital Timer may be provided to start and stop 24 hour / 7 day
oven operation. This timer enables the oven to shut off at night and turn on and ramp back to temperature
before the work day starts. The timer can be programmed to have different hours of operation for any day of
the week. It can also be programmed with up to 10 on/off cycles, which can be assigned to any combination
of days. Circular programming keys are provided with an LCD display that shows various data and
information.

Normally open output contacts of the timer are wired in series with the Heater Contactor. When the
programmed start time is reached, timer contacts will close to energize the contactor which will start the

controller. When the programmed stop time is reached, timer contacts will open to remove power from the
circulation blower and heater.
