Connect the thermocouple to the designated port on the unit.
Powering On
Turn on the Main power switch. The Eurotherm controller will initiate self-tests and display the ambient temperature.
Setting Temperature
Use the Up and Down arrows on the controller to select a temperature setpoint. The OP1 light indicates power output to the heating device.
Activating Heat
Turn on the Heat switch to provide power to the heating device.
Ensure the Heat switch is on for the device to receive power.
Intro
The OFITE Temperature Control Unit is a convenient tool for precisely con-trolling the temperature of an electrical heating device. Simply plug the heat-ing device into the Temperature Control Unit and the built-in Eurotherm 2123 controller will regulate the power output to the heater. The controller can be set with either a simple temperature setpoint or an advanced timer.
The Temperature Control Unit is ideal for use with thermocups, hot plates, and heating jackets for filter presses.

PRODUCT OVERVIEW
Operation
- Plug the Temperature Control Unit into an appropriate power source. The power inlet is on the back of the unit.
The four unit model (#171-49-4) has two power inlets on the back. The one on the left provides power to units 3 and 4. The one on the right pro-vides power to units 1 and 2. - Plug the heating device into the Temperature Control Unit. The unit has a power outlet on the front and one on the back.
Do not use both power outlets at the same time. Doing this could cause the unit to draw too much power and blow the fuse. - Plug the thermocouple into the thermocouple port. The unit has a ther-mocouple port on the front and one on the back.
Do not use both thermocouple ports at the same time. Doing this could could result in incorrect readings. - Turn the “Main” power switch on. The Eurotherm controller will run through a short series of self tests. At the end of the tests the display will show the current ambient temperature. This is the home screen.
The four unit model has two “Main” power switches. The one on the left controls units 1 and 2. The one on the right controls units 3 and 4. - Use the “Up” and “Down” arrows to select a temperature setpoint. The “OP1” light in the upper left-hand corner of the display will illuminate when the controller is sending power to the heating device.
- Turn the “Heat” switch on.
The “Heat” switch controls power to the power outlet. If the “Heat” switch is off, the heating device will not receive any power from the Temperature Control Unit, regardless of the reading on the display.
Timer
- Use the “Up” and “Down” arrows to select a temperature setpoint.
- Press the “Page” button until the display reads “SP”.
- Press the “Scroll” button until the display reads “tm.OP”.
- Use the “Up” and “Down” arrows to select one of the five timer programs: Opt. 1 – The controller will engage the heater up to the temperature set point before the timer starts. When the timer times out, the controller will turn off the heater. The display will flash “END” to signal that the timed program is complete.
- Opt. 1 – The controller will engage the heater up to the temperature set point before the timer starts. When the timer times out, the controller will turn off the heater. The display will flash “END” to signal that the timed program is complete.
- Opt. 2 – The controller will engage the heater up to the temperature set point before the timer starts. When the timer times out, the display will flash “END” and leave the heat on indefinitely.
- Opt. 3 – The controller will engage the heater up to the temperature set point while the timer is running. When the timer times out, the controller will turn off the heater. The display will flash “END” to signal that the timed program is complete.
- Opt. 4 – The controller will engage the heater up to the temperature set point while the timer is running. When the timer times out, the display will flash “END” and leave the heat on indefinitely.
- Opt. 5 – The controller will engage the heater up to the temperature set point after the timer times out. The heater will remain on indefinitely and the controller will return to normal operation.
- Press the “Scroll” button until the display reads “tmr”. Use the “Up” and “Down” arrows to set the time (in minutes) that you want the timer program to run.
- Press the “Page” and “Scroll” buttons simultaneously to return to the home screen. The timer program will now begin to run.
- When the timer times out, the controller with enter standby mode (unless Opt. 5 is used). You must exit standby mode before using the timer again.
