Note
The controller will return to the HOME
DISPLAY if left idle for more than a few
seconds.
Note
Once the desired parameter has been
selected, depressing either the UP or
DOWN button will change the parameter

The 8 segment programmable controller
consists of a microprocessor based three-
mode PID (Proportional, Integral, Derivative),
programmable temperature controller with
over-temperature protection and appropriate
output switching devices to control the fur-
nace. The digital readout continuously dis-
plays chamber (upper display) and setpoint
(lower display) temperatures unless the
SCROLL or PAGE button is depressed. The
programmable controller can be used as a
single setpoint controller or as a programma-
ble controller. The 8 segment digital model
enables eight segments of programming.
The 4x16 segment programmable controller
consists of a microprocessor based three-
mode PID (Proportional, Integral, Derivative),
programmable temperature controller with
over-temperature protection and appropriate
output switching devices to control the fur-
nace. The digital readout continuously dis-
plays chamber (upper display) and setpoint
(lower display) temperatures unless the
SCROLL or PAGE button is depressed. The
programmable controller can be used as a
single setpoint controller or as a programma-
ble controller. The 4 program controller has
four 16 segment programs.
Basic Operation
When the controller is turned ON, it will per-
form a short self-test and then change to the
HOME DISPLAY. The HOME DISPLAY shows
the measured temperature (process value) in
the upper display and the desired value (set-
point) in the lower display.
