5 Using Controls and Indicators
5-1 The Microprocessor Controller
The controller is an easy-to-operate microprocessor-based PID
control device. When the process reaches the set point, the
controller cycles the cooling valve or the immersion heater to
maintain the proper To Process temperature.
The controller has been fully factory tested. Set the desired process
temperature set point and the control does the rest.
Built-in range of operation on the controller is 0°F to 400°F (-18ºC
to 205ºC).

Measured Temperature Value Numeric LED
During normal operation, the large green PV Process Value LED
on the controller displays the actual process temperature at the To
Process thermocouple. It also lists parameter symbols during setup
and error messages if an error occurs.
Required Temperature Numeric LED
During normal operation, the smaller green SP Set Value LED on
the controller displays the process set point you want the chiller to
maintain. It also displays parameter and pre-set function values
during setup.
