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 back of 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.

   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.
