Access Levels
The tekmar Snow Detector and Melting Control 664 comes with four Access
Level settings. These Access Levels restrict the number of Menus, Items
and Adjustments that can be accessed by the user. The four access levels
are Limited (LTD), User (USER), Installer (INST) and Advanced (ADV).
The access level of the control is found in the Miscellaneous (Misc) menu
when the Lock / Unlock DIP switch is set to the Unlocked position. In the
Advanced access level, all of the control settings are available to the user.
In the User access level, only a few of the menus and items are available.
The Limited access level is the most restricted of them all. The control’s
factory setting is Installer (INST). This access level is suffi cient for the
normal set up of the control. Once the control is set up, the appropriate
access level should be selected for the people that deal with the control
on a regular basis.
