BUZZER In the event of alarm or error condition, the internal buzzer is activated. To silence the buzzer, press and hold the SET and Down keys for 2 seconds.

LED INDICATIONS

• OUT = Indicates that the heater is on.

Read and understand this entire manual before operating this controller.

VOLTAGE: 120VAC; 240VAC

DISPLAY MESSAGES In normal operation, the sensor temperature will be shown on the display. In case of alarm or error, the following messages will be shown:

• Er = Memory Error

Plug heater into the controller and the controller into its power source. Plug thermocouple into thermocouple jack. Make sure sensing tip is ﬁ rmly attached

• -- = Short-Circuit Probe Error (Disconnects output).

• oo = Open Probe Error (Disconnects output).

to heater. Mount controller using mounting feet. For IBC / tote tank heating applications, attach controller to IBC / tote tank using hanging bracket kit. Push power switch “ON”. Refer to “Programming Instructions” for how to program controller.

CONTROLLER OPERATION: Once the controller reaches set point, the heater will turn off and will not turn on again until the temperature falls 5°F below the set point.

The controller will sound an audible alarm if the temperature at the sensor exceeds 15°F above the set-point.

TROUBLESHOOTING GUIDE

NOTES

Please read this guide prior to contacting OMEGA. This guide is designed to answer the most commonly asked questions. If you are unable to identify the problem or need additional assistance, please contact us at 1-800-USA-HEAT.

Controller does not function

1. Check fuse: Unplug the unit from its power source. Remove the fuse and check its continuity. If the fuse is defective, replace it with an Class CC 15 amp fuse. Fuses may be obtained from most electrical supply houses.

2. Check power source: Using a voltmeter, test the power source and assure correct voltage is present.

3. Check thermocouple: Using a thermocouple meter, test the sensor to assure proper function.
