Wiring
When an existing thermostat controller is replaced, remove and label the wires to identify the terminal functions.
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 2.
Note: For more details on wiring the MS/TP Communications Bus, refer to the MS/TP Communications Bus
Technical Bulletin (LIT-12011034).
2. Attach the communication wires to the terminal block.
Note: If multiple wires are inserted into the terminals, be sure to properly twist the wires together before
inserting them into the terminal connectors.
3. 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.
4. For networked models, set the bus end-of-line (EOL) termination switch to the desired location.
Risk of Electric Shock.
Disconnect the power supply before making electrical connections to avoid electric shock.
Risque de décharge électrique.
Débrancher l'alimentation avant de réaliser tout raccordement électrique afin d'éviter tout risque de décharge
électrique.
Risk of Property Damage.
Do not apply power to the system before checking all wiring connections. Short circuited or improperly connected
wires may result in permanent damage to the equipment.
Risque de dégâts matériels.
Ne pas mettre le système sous tension avant d'avoir vérifié tous les raccords de câblage. Des fils formant un
court-circuit ou connectés de façon incorrecte risquent d'endommager irrémédiablement l'équipement.
IMPORTANT: Make all wiring connections in accordance with local, national, and regional regulations. Do not
exceed the electrical ratings of the TEC3000 Series Thermostat Controller.
IMPORTANT: Use proper ESD precautions during installation and servicing to avoid damage to the electronic
circuits of the thermostat controller.
