The oven temperature controller is configured and tuned at the
factory to function well for most applications. Occasionally, it
may be advisable to configure the temperature controller
differently to suit a particular working environment or process.
Before reconfiguring the controller, read
this chapter carefully.
the controller can
change the unit characteristics and design

The Temperature Controller senses the chamber air temperature
of the oven (the
PV, or process value) and supplies the heat
necessary to achieve the desired setpoint. The controller includes
an
LED display and a pushbutton keypad. Refer to Table 2 and
Table 3 for lists of displayed parameters and keypad functions.
The UP150 controller will accept a single program of up to 16
segments. This controller includes an automatic tuning feature
and "Super" control to improve the performance. Refer to the
UP150 manual for detailed information.
