Note:
Seal the hole in the wall with fireproof material to prevent drafts from affecting the
ambient temperature readings.
4. For networked models, set the bus end-of-line (EOL) termination switch to the desired location.
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.

5. 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 needs to match the base board number. Otherwise, an operation error occurs
after you reattach a cover and base that do not belong together (as shown in the following
figure). See the following table for TEC3000 model names and code numbers.
