OMRON Quick Start Instruction E5CC 1.5 Setting temperature shift If the temperature on the controller display deviates from your measured value (for instance due to ageing of the sensor), you can set a temperature shift. Enter the shift using the ins (input shift) parameter. 1. Press the 1st button briefly until l.adj is displayed. 2. Then press the second button briefly several times until ins is displayed. 3. The value entered here shifts the temperature up or down. If you enter -10, the measured temperature is decreased by 10 degrees. 1.6 Hysteresis If the controller is set to ON-OFF, you can change the hysteresis. The hysteresis is a switching point above and under the set point.
A higher value limits the number of switches, but leads to less accuracy in temperature readings. 1. Go to the hys parameter by briefly pressing the 1st button once until l.adj is displayed. 2. Then press and hold the 2nd button until hys is displayed. 3. The default value is 1.0. You may increase or decrease this value. Caution! Hysteresis is not available if the controller is set to PID. Example: Suppose the desired temperature (set point) is set to 50 degrees. The controller heats to 50 degrees and then stops. The temperature will fall below 50 degrees before the controller switches on again. Suppose the hysteresis is set to 2 degrees; the controller will then switch on at 48 degrees. 16
