tN4 System Control (DIP Switch #2)
A tN4 System Control is a control, not a thermostat, that
the 545 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 545.
•
• 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 545. Set
the tN4 System Control’s Lock / Unlock DIP switch to the
Unlock position before Access Levels can be changed on
the thermostat.
