Sequence of Operation
When the “Accu-Steam™ G2” griddle is plugged in, AC line voltage is supplied to the lead-in contacts
of the contactor. From the contactor, line voltage is supplied to the primary side of the transformer. The
secondary side voltage out is 24VAC nominal. One leg of the secondary side of the transformer (24VAC) is
split and is connected to the contactor coil and the Hi-Limit thermostat. From the HI-Limit thermostat, the
24VAC leg is daisy chained to the main digital control board. The other secondary leg of power from the
transformer goes to the Hi-Limit and then daisy chains over to the main digital control board. At this time,
the system is waiting to be powered on via the Digital control board. Upon pressing the “ON” button on the
digital controller, the digital controller powers up and a relay on the digital controller is closed, thus making a
connection between one of the two 24VAC legs and the input of the HI-Limit thermostat. If the reading from
the Hi-Limit RTD (Resistive Thermal Device) is not too high, an output relay in the Hi-Limit controller will
be closed causing the contactor to pull in. Once the contactor pulls in, line voltage is sent to the solid state
relays and heating elements. If the internal temperature of the griddle is below the set point of the digital
controller as measured by the digital controller RTD sensor, the digital controller will output 24VDC to the
control side of the solid state relays, turning them on. When the solid state relay(s) are turned on, line voltage
is sent through the SSR connection to all the heating elements and the griddle heats up. When the griddle
heats up to the set point temperature, the digital controller RTD resistance changes and provides a signal to
the control board telling it that the set point temperature has been reached. When the digital controller sees
the resistance value for the set point temperature, it cuts power to the SSR(s) and breaks the connection to
the elements causing the griddle to stop heating further.

To Set Preset Temperature:
To set temperature, press either the UP arrow key or the DOWN arrow key and hold for approximately 3
seconds. The controller will load and display Default Cook Temp and enter set temperature mode.
Press the UP arrow key to increment or the DOWN arrow key to decrement from the current temperature
setting. Once the correct temperature is displayed, and before the fi ve second time out, press and hold the Preset
Temp 1 key or the Preset Temp 2 key to save the displayed value to the desired preset key and to exit this mode.

To Set User Lockout Mode (Manager’s Mode):
To Set USER LOCKOUT mode, press and hold the 0/1 key and the TEMP key for approximately 4 seconds
while the controller is ON.
After 4 seconds, the USER LOCKOUT parameter will toggle and the display will show either “Loc” or
“ULoc”. When buttons are released, the controller will store the new USER LOCKOUT parameter value into
