General Description

This control turns the output on and off around your established temperature. With thermocouple input you can
now dial in your desired setting and the control will regulate the temperature. This type of control is ideal for
many applications but should not be used for critical temperature processes. This unit comes with digital display
of setpoint, 6’ detachable power cord and grid support bracket, which is ideal for fume hood mounting to
maximize bench space.

Operation is stable in ambient temperature from 30 to 130 degrees F. 0 to 90% RH, non-condensing

Control Features

1. On/Off switch.

2. 15-amp output.

3. Non-Linear control (scale is for reference only)

4. Circuit protection

5. Low profile housing.

How to Setup and Operate

First connect the heater load (sized as shown below) and the thermocouple plug to the load and thermocouple
receptacles on the rear of the control. Next plug the control line cord into the appropriate 3-wire grounded power
receptacle. Push the power switch to the “ON” position to apply power to the control. Turn the control knob to the desired
temperature setting. The “LOAD” pilot light on the front panel indicates where there is power to the load. The control is
accurate within + or – 1% of full scale.

Operator Interface

- Control knob

- Digital setpoint display

- ON/OFF switch

- Output pilot light

- Type J thermocouple receptacle

- 3-wire load receptacle

Accuracy

- Calibration accuracy: + or - 1% of span. +/- 11.0°C

- Set point accuracy: + or - 3% of span maximum.

Control Sensor

This control requires a type “J” an Iron-Constantan thermocouple. The control may be used with any type “J
“thermocouple which has a lead resistance less than 100 ohms.

Proper placement of the thermocouple can eliminate many problems in the total system. The probe should be placed so
that it can detect any temperature change with little thermal lag. In a process that requires fairly constant heat output, the
probe should be close to the heater. In processes where heat demand is variable, the probe should be close to the work
area. Some experimenting with probe location can be tried to provide optimum results.

Maintenance

Simple preventative maintenance steps include keeping the controller clean. Protect it from overload, excessive dirt, oil
and corrosion.
