After the controller is properly wired into the system, the user only
needs to verify the sensor input and control type and adjust the set point.
Setting the Sensor and Control Mode
Adjust the dip switches located on the bottom of the unit as shown in
Figure 1.1. The factory settings are J, TC, °F, and PI. It is simpler to
adjust the dip switch prior to mounting the 2110.

2. To adjust the set point on the Chromalox 2110 Temperature Controller,
press and hold the Set Point button (see Figure 1.2). The Set Point
light is illuminated.
3. While still pressing the Set P oint button, press either the or button
to adjust the set point to the desired value (see Figure 1.3). Holding

Inspection and
Unpacking
Your Chromalox 2110 controller should arrive in good condition. Upon
arrival, inspect the packaging for any visible damage.
Unpack the controller and carefully inspect for product damage that may
have occurred during shipment. If the package or contents have been
damaged in shipping, you must file a claim with the delivery service.
The delivery service will not accept a claim from the shipper.
If not immediately installing the controller, store in a cool, dry environ-
ment in its original protective packaging. Temperature extremes and
excessive moisture can damage the instrument.

The Chromalox 2110 Temperature controller offers simple setup,
flexibility and control features in an attractive, compact design. The
2110 is housed in a rugged, plastic 1/4 DIN package that only requires
four inches behind the mounting surface. Straightforward operation and
easy-to-use control features are major strengths of the 2110 controller.
Easy Three-Step Setup: The 2110 delivers exceptional process tempera-
ture control. Your process is up and running after three easy setup steps:
1) Select the sensor and control type, 2) Hook up the system and
3) Select the desired temperature.

Type Selection
Switches
Set the Chromalox 2110 controller’s configuration via mechanical dip
switches, located on the bottom of the unit. Factory settings are J, TC,
°F, and PI Control. Switches are easier to set before mounting.
To change the switch settings, first disconnect all wiring and power from
the unit. Adjust switch settings as follows:
Setting Factory
Switch Function Options Setting
A Thermocouple J or K J
B Input Type TC or RTD TC
C Temperature Units °F or °C°F
D Control Type ON-OFF or PI PI
If input type is thermocouple, switch A selects either thermocouple type
Jor K.
Switch B selects input type thermocouple or RTD (resistance tempera-
ture detector). Note: If RTD is selected, switch A is ignored.
Switch C selects temperature units °For °C.
Switch D selects either PI (Proportional-Integral) or ON-OFF control.

Mounting Two mounting collars securely hold the 2110 controller in the mounting
hole. Remove these mounting collars before installation.
Removing Mounting Collars
1. To remove the rear collar, press the sides of the collar. This releases
holding tabs on the top and bottom of the collar.
2. Slide the collar off the back of the unit.
3. Slide the front collar off the back of the unit

1. Cut out a 1/4 DIN, 3.6-inch (92mm) square hole in the mounting
panel.
2. Insert the unit into the mounting hole as shown in Figure 3.4.
3. Slide the front mounting collar onto the back of the controller.
4. Slide the rear mounting collar onto the back of the controller until the
holding tabs securely engage with the holding tab slots in the control-
ler housing (see Figure 3.4).
5. Tighten the four rear collar mounting screws until the unit is held
firmly in the panel. CAUTION: Do not overtighten.
The controller will now be held firmly in place.

Good Wiring
Practices
Separate wire into bundles—When planning the system wiring,
separate wiring into functionally similar bundles, e.g.
• Power leads
• Sensor leads (if power leads must cross sensor leads, they should
cross at a 90°angle)
• Output signal lines
Separate sources of electrical noise—Locate all sources of electrical
noise in your system, and separate these sources from the control
system, e.g.
• Motors
• Contacts
• Solenoids
Electrical noise can affect the function of any control system. When
driving a contactor coil or other inductive load, an appropriate rated AC
snubber circuit is recommended (Chromalox Part No. 0149-01305).
Connect before power is applied—Make all electrical wiring connec-
tions to the back of the controller before power is applied to the unit.
Comply with regulations—WARNING: All wiring practices must
comply with local regulations. Failure to do so could result in damage
to controller and/or personal injury or death from electrical shock.
This instrument is intended for panel mounting and the terminals must
be enclosed within a panel. Use National Electric Code (NEC) Class 1
wiring for all terminals except the sensor terminals.
Check wiring decal—Check the wiring decal on the side of the unit to
verify the model number. The wiring decal shows the wiring termina-
tions. All wiring will be connected to the terminals on the back of the
instrument case. Specific wiring instructions for different input and
output types are given in this section. See also Figure 3.5.
Additional information—For sensor wiring practices, see “Sensor
Input Wiring”. For additional information on good wiring practice,
request IEEE Standard No. 518-1982 from IEEE, 345 East 47th St., New
York, NY 10017 or www.ieee.org.

Chromalox 2110 8Section 3–Installation and Wiring
Sensor Input Wiring Sensor Wiring Notes
For safety and best controller performance,
•Sensor leads (thermocouple and RTD) should not be run in the same
conduit as power wiring.
•Twisted pair, shielded wire is recommended for sensor connections.
•False temperature readings can occur if the sensor wire is exposed
to electrical noise.
•Ungrounded thermocouples are recommended.
•Thermocouple extension wire, if required, must be the same type
as the thermocouple (i.e. if a Type K thermocouple is used, then Type
K extension wire must be used.)
•Shielded thermocouple wire, if used, must have the shield
grounded at one end only, preferably at the shield ground terminal on
the controller as shown in Figure 3.6.
•Three-wire RTDs are recommended for greatest accuracy.
•
Standard shielded copper wire is recommended for RTD extensions.
Thermocouple Inputs
It is important to observe polarity (+,-) when connecting thermocouple
leadwires. ANSI color coding for the thermocouples used with this
instrument are
Thermocouple
Type Material Polarity (+) Polarity (-)
J iron/constantan white red
K chromel/alumel yellow red
Make thermocouple wiring connections to terminals as shown in Figure
3.6.

2110 Temperature Controller
Chromalox 2110
Three-Wire RTD Inputs
IMPORTANT: When making the three-wire RTD input connection,
make the resistance of all three extension leadwires equal by using the
same gauge and same length of wire for optimum accuracy. A three-wire
RTD will generally have two wires of the same color. Connect the same
colored wires to the RTDL connections. Connect the alternate colored
wire to the RTDH connection.
Make three-wire RTD connections to terminals as shown in Figure 3.7.
Two-Wire RTD Inputs
If using a two-wire RTD input, use heavier gauge leadwires to reduce
leadwire resistance. Any leadwire resistance adds directly to sensor
resistance, thus adding error to the process temperature measurement. It
is also necessary to jumper the two RTDL terminals on the instrument to
complete a two-wire hookup.
