3.2.6 Overheat Reset Switch
Figure 5. Right Side Panel
If the unit is operated at high temperatures in elevated ambient temperatures,
an overheat condition may occur. In an overheat situation a mechanical reset
switch on the right side panel will pop and open the heater circuit (see figure
5). The controller will still have power. While the controller will be demanding
heat from the heater, the process temperature will fall continuously until it
equalizes with room temperature. If an overheat condition occurs, let the unit
cool off for one hour (leave unit on), then press the reset button, firmly. If this
does not correct the problem, contact the factory.

The power switch has two positions, “ON” and “STANDBY.”
STANDBY ON
In the “ON” position, the entire unit is powered up.
In the STANDBY mode, the unit is powered down except for the fan. If the unit
has been operated at high temperature and is then put into standby mode,
the fan will continue to run until the probe well has cooled down to room
temperature.
