2216 Controller
1 2216 – DESCRIPTION
1.1 2216 Controller
The model 2216 controller is made by Eurotherm, and is fitted by Carbolite configured for
immediate use. It is a digital instrument with PID control algorithms. It is supplied as a sleeve
fitted controller.
The 2216 is supplied configured for easy use as a simple temperature controller, where on setting
the required temperature the controller immediately attempts to reach and maintain it.
A ramp-to-setpoint feature is available which may be used to limit the heating rate. This is shown
diagrammatically in figs 1 & 2.
The controller does not contain a real-time calendar, and is not subject to century-end date
problems.

2 2216 – BASIC OPERATING INSTRUCTIONS
2.1 Furnace or Oven Controls
Most Carbolite products are fitted with an “Instrument Switch” which cuts off power to the
controller and other parts of the control circuit. See the instruction manual for the furnace or oven
for the overall operating instructions.
To operate the 2216 there must be power to the furnace or oven, and the Instrument switch must
be on. If a time switch is included in the furnace or oven circuit, this must be in an On period.
2.2 The 2216 – Operation
When switched on, the controller lights up, goes through a short test routine, and then displays
the measured temperature and starts to control. The output light glows or flashes as heating
occurs.
The Page key allows access to parameter lists within the controller; most lists and parameters
are hidden and cannot be accessed by the operator because they contain factory-set parameters
which should not be changed.
A single press of the page key displays the temperature units, normally set to °C; further
presses reveal the lists indicated in the Navigation Diagram in section 2.6. The Scroll key
allows access to the parameters within a list. Some parameters are display-only; others may be
altered by the operator. Some parameters only appear in appropriate circumstances – for
example, working setpoint does not appear if setpoint ramp rate is Off.
A single press of the scroll key displays the temperature units; further presses reveal the
parameters in the current list indicated in the Navigation Diagram.
To return to the Home list at any time, press Page and Scroll together, or wait for 45
seconds.
The Down and Up keys are used to alter the setpoint or other parameter values.
2.3 Basic Operation
Normally no operator action is required other than entering the setpoint, as the 2216 starts to
control on being switched on, as described above.
