Intro
The OFITE Temperature Control Unit is a convenient tool for precisely
controlling the temperature of an electrical heating device. Simply plug the
heating 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 thermocouples, hot plates,
and heating jackets for filter presses.

Operation
| 1. 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 provides power
to units 1 and 2.
---|---
| 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.
| 3. Plug the thermocouple into the thermocouple port. The unit has a
thermocouple port on the front and one on the back.
Do not use both thermocouple ports at the same time. Doing this could result
in incorrect readings.
| 4. 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.
| 5. 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.
| 6. 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.

Opt. 2 – The controller will engage the heater up to the temperature setpoint 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 setpoint 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 setpoint 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 setpoint after the timer times out. The heater will remain on indefinitely and the controller will return to normal operation. -
