Error LEDs

The APCETHD is smart enough to monitor the temperature and

humidity levels and to alert the user to a problem with any of the

devices connected to the APCETHD. Here is how it works.

As the unit functions normally, the environmental conditions

(temp & humidity) will be slowly but steadily changing. These

small changes are detected by the controller.

If the controller does not detect a slight change in one (or more)

environmental conditions within a 1-hour period, the unit will de-

activate the affected output and the appropriate green Error LED

will be flashing to indicate which device may have a problem.

This safety feature is extremely important and useful to

eliminate "runaway" conditions which could result in crop damage

or other more serious problems.

If any of the Error LEDs are blinking, the user should refer to the

example below to help identify the actual cause of the error.

* EXAMPLE: The Cooling error LED is flashing, it means that

the device connected to the Cooling output either did not

turn on OR that there is a problem with the temperature

sensor. Check the cooling device for proper operation and

verify the remote sensor is reading properly.

Note:

To reset an error, press the Enter / reset button.
