TEC26x7-4 Series BACnet® MS/TP Networked Thermostat Controllers with Two Outputs Installation
Instructions
Wiring
When an existing thermostat controller is replaced,
remove and label the wires to identify the terminal
functions. When a TEC26x7-4 Series Thermostat
Controller is replaced, simply remove the old screw
terminal blocks and reinsert them onto the PCB of the
replacement thermostat controller.
To wire the thermostat controller:
1. Strip the ends of each wire 1/4 in. (6 mm) and
connect them to the appropriate screw terminals as
indicated in Table 1 and Figure 5 through
Figure 18.
Note: For more details on wiring the MS/TP
Communications Bus, refer to the MS/TP
Communications Bus Technical Bulletin
(LIT-12011034).
2. Carefully push any excess wire back into the wall.
Note: Seal the hole in the wall with fireproof
material to prevent drafts from affecting the
ambient temperature readings.
3. Reinsert the screw terminal blocks onto the PCB.
4. Reattach the MS/TP communication wires to the
terminal block.
Note: If multiple wires are inserted into the
terminals, be sure to properly twist the wires
together prior to inserting them into the terminal
connectors.
5. Reattach the thermostat controller cover to the
mounting base (top side first).
6. Use a Phillips-head screwdriver to reinstall the
security screw on the bottom of the thermostat
controller cover.
IMPORTANT: Because some of the objects may
not directly correlate to a previous version, you must
rediscover all point objects for the TEC26x7-4
version. For detailed information on this mapping,
refer to the TEC BACnet® MS/TP Network Series
Thermostat Controllers Technical Bulletin
(LIT-12011592).

regulations. Do not exceed the electrical ratings of
the TEC26x7-4 Series Thermostat Controller.
