1 The two-character code number is listed within the error code to indicate that the CPU board and base board do not
belong together. However, if the same code number appears as both the CPU board and base board, there is no error.
For example, if 0C is listed as the CPU board and the base board, the model is the TEC3612.
6. 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.
7. 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, since they may damage the polarizer.
Note:
- For VAV and two-pipe systems, connect the valve to the heating output.
- Only one transformer is required for each TEC.
- Power to the AUX contact comes from the reheat coil.
See Figure 8Figure 8, Figure 9, and Figure 10 for wiring diagrams. See the following table for termi-
nal identification.
