the place of the standard drawer warmer control panel. Use
the following procedure to operate the digital temperature
controller.
Startup
1. Move the Power I/O (on/off) switch(es) to the I (on) position.
• The corresponding digital temperature controller will
energize and the current temperature of the drawer or
"LO" will appear on the TEMPERATURE display. "LO"
indicates the drawer temperature is below 21°C (70°F).

setpoint temperature, refer to "Changing the Setpoint
Temperature" in this section.
NOTE: The digital temperature controller is pre-set to a setpoint
temperature of 85°C (185°F) at the factory. Once the
setpoint temperature is changed, the new setpoint
temperature will remain in memory until it is changed
again. The minimum to maximum setpoint temperature
range is 21°C (70°F) to 93°C (200°F).
