mode.
4.7.2 Temperature and Unlock Buttons
The TEMP button (see Figure 1), if pressed once while the fryer is on, displays current vat
temperature on both sides. If the TEMP button is pressed twice, it shows the setpoint temperatures
of the vats. If the fryer is off, the display shows the current versions of software. The UNLOCK

allows access to Tech Mode.
