TEC3000 Series Networked and Wireless Proportional Fan Coil and Individual Zone Thermostat Controllers with
Dehumidification Capability Quick Start Guide
7
The bus EOL termination switch allows you to designate the thermostat controller as the end of the Field
Controller (FC) Bus and N2 Bus. The default position is OFF. If the thermostat controller is at the end of a daisy
chain of devices on the FC Bus and N2 Bus, set the EOL switch to the ON position. See Figure 3.
5. Reattach the thermostat controller cover to the mounting base (bottom side first).
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.
Notes:
• 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.
IMPORTANT: Make sure you reattach the cover that corresponds to its correct base. The CPU board number
needs to match the base board number.
Otherwise, an operation error occurs after you reattach a cover and
base that do not belong together.
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.
