Security Codes
This controller has two levels of security protection with separate security codes.
The first level allows entry into the Calibration mode: security code = 11; the second
allows entry into the SETUP mode: security code = 22.
The security codes protect the controller from unauthorised tampering of its current
setting. The parameters cannot be changed unless the security code is entered.
