Part II: attach wIres to thermostat wallPlate (cont.)
2. Using a small fl athead screwdriver, loosen the screws on the terminal blocks that
correspond to the system type (see Table 1).
3. Strip the insulation of each wire at a proper length (about 1/4" or 64 cm).
4. On the wallplate, insert wires into the terminal blocks that correspond to the system
type, then re-tighten each screw for each terminal (see Fig. 4, enlarged area).
note: Do not over-tighten screws or use excessive force.
5. Assure that no uninsulated wires are exposed: Cap off and place a wire-nut on any
unused wires. Assure that the attached wires fi t into the cavity on the back side of the
thermostat.

terminal blocks.
Part III: connect Power to the thermostat wallPlate
1. Choose from the following options to power the thermostat.
Power options
The T12000 Series will operate on 24 VAC power and/or two AA batteries (both are
recommended). Choose from three methods to connect power to the thermostat.
• Batteries only (AA alkaline)
• 24 VAC direct connection only
• 24 VAC with AA battery backup (highly recommended)
wiring 24 vac common
• single-transformer system: Connect the common side of the transformer to
the "C" screw terminal of the thermostat wallplate. Assure that the metal jumper
connects "RC" and "RH." Connect power side to the RC/RH and assure that the
jumper remains in place.
• two-transformer system: The T12000 Series is shipped with a jumper connecting
terminals RH and RC. If the heating and cooling equipment do not use separate
transformers, leave this jumper in place. If separate transformers are required,
remove this jumper. With the jumper removed, connect RC to the power side of the
cooling transformer. Connect RH to the power side of the heating transformer; then
connect both the heating and cooling commons together to terminal C (Common).
