Setting Slider Tabs (Built-In Jumper); Uwp Wiring Terminal Designations - Honeywell T1 Pro Installation Instructions Manual

Setting Slider Tabs (built-in jumper)

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 Tab for U terminals should be left
in place for T1 Pro models.
