The Intermatic / Grasslin Model FM1D 24 Hour / 7 Day 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 20 on/off cycles, which can be assigned to
any combination of days. A large LCD display provides comprehensive information about your time settings.
Process Cycle Operation:
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
circulation blower and enable the heat control output. Power to the heater is controlled by the main
temperature controller. When the programmed stop time is reached, timer contacts will open to remove
power from the circulation blower and heater.
