used, depending
on the system
type that is being
wired. The most
commonly used
terminals are
shaded.
* Terminal can be jumped using Slider Tab. See “Setting Slider Tabs” above.
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.
Setting Slider Tabs
Insert R and C wires into
designated terminals
for primary AC power (C
terminal is optional if
batteries are installed,
but it is recommended).
Remove wires by
depressing the terminal
tabs.
Insert AA
