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.
