UWP Mounting System installation 1. Open package to find the UWP. See Figure 1. 1 2 2. Position the UWP on the wall. Level and mark hole positions. See Figure 2. Drill holes at marked positions, and then lightly tap supplied wall anchors into wall using a hammer. ‒‒ Drill 7/32” holes for drywall. 3 4 1/4” 8” to 3/ 3. Pull the door open and insert wires through wiring hole of the UWP. See Figure 3. 4. Place the UWP over the wall anchors. Insert and tighten mounting screws supplied with the UWP.
Wiring UWP Push down on the tabs to put the wires into the inner holes of their corresponding terminals on the UWP (one wire per terminal) until they are firmly in place. Gently tug on the wires to verify they are secure. If you need to release the wires again, push down the terminal tabs on the sides of the UWP. This wiring is just an example, yours may vary.
Setting Slider Tabs Set R Slider Tab, see Figure 9. • Use built-in jumper (R Slider Tab) to differentiate between one or two transformer systems. 9 • If there is only one R wire, and it is connected to the R, Rc, or RH terminal on the old thermostat, 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). Set U Slider Tab, see Figure 10.
Wiring NOTES: 1 Available wiring configurations differ by product models/product numbers. 2 Use 18- to 22- gauge thermostat wire. Shielded cable is not required. 3 Set the R Slider Tab on the UWP to the up position (1 wire) for 1 transformer systems or the down position (2 wires) for 2 transformer systems. See "Setting Slider Tabs" on page 4. 4 Set the U Slider Tab to the up position (1 wire) for non-powered ventilation or the down position (2 wires) for powered ventilation.
