25 , a high temperature alarm occurs if the process air temperature rises more
than 25
° above the process air temperature set point.

temperature and displays dew point, you can restore the controller to factory setup.
1/16 DIN E5CK Operating Parameters
The E5CK controller has several mode selections. Within each mode are numerous parameters
that can be set. Before you can access the several modes of operating parameters, you must
change the security lock-out of the controller. AEC factory sets the security level to protect the
parameters from being accidentally changed. Below is an explanation of the operating modes,
how to change out the security level and the AEC default settings.
