Emerson DE Manuel D’Utilisation

The following table lists choices on the Select Options menu. These should match the options installed 

with your unit and should not need to change during normal operation.

The temperature and humidity sensors can be calibrated by selecting this menu item. “Sensor” shows 

the actual sensor reading or raw reading. “Calibrated” shows the sensor reading after the calibration 

offset has been added. The temperature sensor can be calibrated ±5 degrees Fahrenheit and the 

humidity sensor can be calibrated ±10% RH. When calibrating the humidity sensor, the value shown 

will always be % RH, even though absolute humidity control may be selected. If absolute humidity 

control is selected, the Normal Status Display will display the adjusted reading and may not agree 

with the relative humidity reading displayed while in calibration.

The DIP switch settings can be reviewed from the display panel. Changing the DIP switches requires 

opening the upper panel for access to the DIP switches on the microprocessor control board.

These selections should match options installed on your unit and should not need to change during 

normal operation. Switches 1 through 6 are self-explanatory. Switch 7 is described in more detail 

below. DIP switch 8, not shown above, enables the password feature when set to ON and disables the 

password feature if set to OFF.
