2132 and 2116 PID Temperature Controllers
Thank you for choosing the 2132 or 2116 Temperature Controller. Supplied in 1/32 and 1/16 DIN panel sizes they
are designed for accurate, stable control of ovens, chillers, sterilisers and other heating and cooling processes.
Two outputs are configurable for heating, cooling and alarms.
The controller is supplied configured according to the order code given in section 5. Check this on the side labels
to determine the configuration of your particular controller.

1.1 To Install the Controller
Please read the safety information in sections 7 before proceeding.
1. Prepare the panel cut-out to the size shown
2. Insert the controller through the cut-out.
3. Spring the panel retaining clips into place. Secure the controller in position by holding it level and pushing
both retaining clips forward.
4. Peel off the protective cover from the display
1.2 Unplugging the Controller
The controller can be unplugged from its sleeve by easing the latching ears outwards and pulling it forward out of
the sleeve. When plugging it back into its sleeve, ensure that the latching ears click back into place to maintain the
IP65 sealing.
1.3 Recommended Minimum Spacing of Controllers
10mm (0.4 in) 38mm (1.5 in)
(Not to scale)

2. Electrical Connections
2.1 Wire Sizes
The screw terminals accept wire sizes from 0.5 to 1.5 mm
(16 to 22AWG). Hinged covers prevent hands or metal
making accidental contact with live wires. The rear
terminal screws should be tightened to 0.4Nm (3.5lb in).
Output ratings
Logic Output: 9Vdc, 12mA (non-isolated from
sensor input).
Used for: Heating, Cooling or Alarm.
Relay Output: 2A, 264V ac resistive.
Used for: Heating, Cooling or Alarm.
Contact Closure Input (replaces Logic Output).
Used for: Alarm Acknowledge or Timer start/reset

2.2 Typical Wiring Diagram
Safety requirements for permanently connected equipment state:
•A switch or circuit breaker shall be included in the building installation
•It shall be in close proximity to the equipment and within easy reach of the operator
It shall be marked as the disconnecting device for the equipment
*When switching
inductive loads such as
contactors or solenoid
valves, wire the
22nF/100Ω‘snubber’
supplied across relay
terminals AA & AB. This
will prolong contact life
and reduce interference.
!WARNING
Snubbers pass 0.6mA at
110V and 1.2mA at
230Vac, which may be
sufficient to hold on high
impedance loads. Do not
use in these installations.

3. Operation
Switch on the controller. Following a 3 second self-
test sequence, you will see the display shown below.
It is called the HOME display.
OP1 illuminates when the logic output is ON
(normally heating).
OP2 illuminates when the relay output is ON
(normally cooling or alarm).
If OP1 or OP2 are configured as alarm outputs
(instead of heating and cooling), they will flash when a
new ‘unacknowledged’ alarm occurs and go steady
when the alarm is acknowledged but still true.
3.1 To Adjust The Required
Temperature (Setpoint)
Press and release quickly the or button.
The setpoint will be displayed for 2 seconds.

3.2 To View The Display Units
Press and release quickly the or button. The
display units will be flashed for 0.5 sec.
If you get lost, pressing and together will
always return you to the HOME display.
If, at any time, no key is pressed within 45 seconds,
the display will always return to the HOME display.
3.3 To Acknowledge a New Alarm
Press and together. This will also reset any
latched alarms that are no longer true.
3.4 Alarm Messages
If an alarm occurs a message will be flashed in the
display. This alternates with the measured temperature
as shown below:
Possible messages
-fsH Alarm - Full Scale High
-FSL Alarm - Full Scale Low
-deV Alarm - Deviation
-dHi Alarm - Deviation High
-dLo Alarm - Deviation Low

3.5 To View The Output Power
Do this if you want to see how much heating or
cooling energy is being demanded by the controller.
Note: This is not a measure of actual power.
Warning!
In manual standby mode (see ‘To Use The Timer’) the
output power can be adjusted by the operator, causing
heating or cooling to be permanently applied. To
prevent this make the OP parameter read only (see ‘To
Hide, Reveal And Promote Parameters’)

3.6 To Select or Change Other
Parameters
Parameters are settings in the controller which you can
change to suit the process. They are found under list
headings.
Press the button to step through the list headings
as shown below.
Turn to paragraph 3.8 to see all of the list headings.
These lists are used to:
•Change alarm setpoints
•Tune the controller to the process
•Manually select PID values
•Change setpoint limits and access the in-built
timer
•Change input and output limits
Keep pressing to select
more list headings, eventually
returning to the HOME display.
This is a continuous loop.

3.7 To Adjust The Alarm Setpoints
(Trip Levels)
Press twice to choose the AL list.
There are three Alarms. The setpoint for each alarm is
found under the AL list. If an alarm has been disabled, it
will not appear in this list.
Note: The other parameters listed in section 3.8 are
accessed and adjusted in exactly the same way as this
