Dip Switches

tN4 System Control (DIP Switch #2)

A tN4 System Control is a control, not a thermostat, that the 544 thermostat connects to through the tN4 bus. All tN4 compatible Outdoor Reset Modules are tN4 System Controls.

• If the thermostat is connected to a tN4 System Control, set the tN4 System Control DIP switch to tN4 System Control (down position).

• If the thermostat is not connected to a tN4 System Control, set the tN4 System Control DIP switch to None

(up position).

Lock / Unlock (DIP Switch #1)

Use the Lock / Unlock DIP switch to lock or unlock the Access Level of the 544.

• To unlock the Access Level, set the DIP switch to the unlocked (down) position.

• To lock the Access Level, set the DIP switch to the locked (up) position. Once locked, a padlock is displayed in the lower right corner of the display and the Access Level cannot be changed.

Note: The tN4 System Control’s Lock / Unlock DIP switch overrides the Lock / Unlock DIP switch on the 544. Set the tN4 System Control’s Lock / Unlock DIP switch to the Unlock position before Access Levels can be changed on the thermostat.

Access Levels

•

The Access Level restricts the number of Menus, Items and Adjustments that can be accessed by the user. The Access Level setting is found in the Miscellaneous (MISC) menu. Select the appropriate access level for the people who work with the thermostat on a regular basis.
