4. Reattach the thermostat controller cover to the mounting base (bottom side first).
IMPORTANT: Make sure you reattach the cover that corresponds to its correct base. The CPU board number

cover and base that do not belong together as shown in Figure 4. See Table 2 on page 7 for TEC3000 model
names and code numbers.

5. Use a 1/16 in. (1.5 mm) Allen wrench or Johnson Controls T-4000-119 Allen-Head Adjustment Tool (order
separately) to reinstall the security screw on the top of the thermostat controller cover. See Figure 2 for security
screw placement.
6. Remove the protective plastic cover sheet from the display.
IMPORTANT: If the display is dirty, gently wipe it clean with isopropyl alcohol or ethyl alcohol. Do not scrub
hard as to avoid damaging the surface. Do not use other cleaners such as water, ketones, and aromatic
solvents, as they may damage the polarizer.
Note: Only one transformer is required for each TEC.
