1.0 Introduction
The 132 is a simple temperature controller that uses PID (Proportional Integral
Derivative) algorithms to adjust the heating power and control the temperature within
the product.
Users navigate through the controller by pressing the four buttons positioned at either
side of the display.

2.0 Operation
To change the setpoint:
1. Use the up and down buttons to adjust the setpoint to the desired temperature.
2. Press the Menu/OK button to accept the new value. OK will appear briefly on the
lower half of the display.
The example pictured shows the setpoint being adjusted from 300°C to 500°C.

2.1 Sensor Break
If the thermocouple breaks or becomes disconnected, then the controller will register a
sensor break, and cut power to the heating elements.
The display will show SBRK and a scrolling SENSOR BREAK message.

2.2 Working Output Power
During heating, the 132 controller displays the working output power of the product as
a percentage value. It is referred to as OUTPUT LEVEL DISPLAY.
To view the working output power:
1. Press the Menu/OK button to access the controller menu. The scrolling text on the
lower half of the display should show USERLEVEL.
2. Press the Menu/OK button to access further information.
3. Press the up and down arrow buttons to scroll through and view the following
information:
lCURRENT SETPOINT (desired temperature)
lMEASURED VALUE (actual temperature)
lOUTPUT LEVEL DISPLAY (working output power)
4. To return to the home display, press the return button to navigate back through
the controller menus.

3.0 Autotuning
All Carbolite Gero products are preconfigured for optimum performance when used
within their normal expected operating temperature range.
Depending on the intended application, it may be necessary for the product to be used
outside of this normal range, in which case some tuning may be required in order to
optimise the PID controls within the temperature controller e.g. if a high temperature
product is to be used at a significantly lower temperature than it was originally
designed for, or if a particularly heavy sample/load is to be heated.
To autotune the 132:
1. Enter the setpoint temperature that you wish to autotune the controller to e.g.
500°C.
2. From the home display, press and hold both the up and down arrow buttons
(more than 5 seconds) until AUTOTUNING ACTIVE appears.
3. When the autotuning process is complete, the controller will return to the default
home display.
Note: To cancel the autotuning process, press and hold both the up and down arrow
buttons until the controller returns to the default home display.
