Wiring
NOTES:
1. Use 18- to 22- gauge thermostat wire. Shielded cable is not required.
2. 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.
3. Set the U Slider Tab as shown in the diagrams on page 4.
4. When T10+ is used with THM04R3000 EIM, wire only R and C to T10+ to power
the thermostat. Then follow the wiring diagrams included in EIM literature.
