Insert AA batteries for primary or backup power.
Setting Slider Tabs
Set R Slider Tab.
Use built-in jumper (R Slider Tab) to differentiate between one or two transformer systems.
If there is only one R wire, and it is connected to the R, Rc, or RH terminal, set the slider to the up
position (1 wire).
If there is one wire connected to the R terminal and one wire connected to the Rc terminal, set the
slider to the down position (2 wires).
NOTE: Slider Tabs for U terminals should be left in place for T6 Pro models.
Wiring terminal designations
Note: Not all terminals may be used, depending on the system type that is being wired. The most
commonly used terminals are shaded.
