Product Description

The Honeywell TR100 Wall Module is an advanced, highly configurable device providing building automation connectivity well-suited for Commercial building applications. TR100 can replace existing Honeywell wall modules using the existing tools familiar to installers. The wall modules utilize Sylk™ communication, which is polarity insensitive and uses two wires. This device supports BACnet™ MS/TP and Modbus™ RTU communications via RS-485 bus, which is necessary for typical HVAC building control systems. Additionally, this bus enables future firmware updates and enhances functionality as they become available on the market.

POWER SUPPLY

Power supply guidelines and requirements

The wall module uses 24 VAC power from an UL Listed  Class- 2 24 VAC transformer (not provided in the kit). It also uses a half-wave rectifier to convert the AC power supply to on-board power. This enables multiple devices with half-wave power supplies to be powered from a single, grounded transformer. Half wave devices and full wave devices must not use the same AC transformer.

You must maintain wiring polarity. Failure to do so can result in equipment damage. If the HVAC equipment has an internal circuit board that is powered by the same transformer that will power the wall module, verify  that it is NOT full wave.

Power supply wire sizing

Long power supply wiring runs require selecting the wire gauge appropriately. If the wire gauge is inadequate the increased resistance and associated voltage drop may result in an insufficient voltage supply to the Wall module.

The recommended wire gauge 14-26 AWG (0.2-1.5 mm2 for solid or stranded, max 2.5mm2 for solid) wires.

WARNING
Ensure that TR100 Wall module power connections only use R and C terminals. COM should only be used for analog inputs/outputs.  Failure to follow these instructions may result in Wall module operational and communication failures or equipment damage.

MOUNTING

Mounting wall plate on the Drywall

Follow below instructions to mount the Honeywell TR100 Wall module on the drywall. Mount the wall plate vertically on the wall.

NOTE: If you are using a TR100 Deco plate for wall module mounting, refer to the Deco plate pocket guide (31-00657).

1. Loosen the security screw (located at the bottom of the wall module) by turning it in counterclockwise direction.
2. Before mounting the wall plate, make sure that the Wall module wires are stripped to the length marked on the wall plate.
3. Position and level the wall plate along the wall and mark the drilling location using a pencil.
4. Remove the wall plate and drill two pilot holes on the wall, on the marks. For drywall, drill 3/16” (5 mm) holes. For firmer material such as plaster, drill 7/32” (6 mm) holes.
5. Gently tap anchors (provided in the kit) into the pilot holes until flush with the wall.
6. Pull the wires through the wiring opening of the wall plate and position the wall plate over the mounting holes. Fig. 8
7. Insert the screws into the holes and tighten (screw torque 0.1 Nm).

Mounting the Wall plate on the Junction Box (Optional)

TR100 can support vertical mounting of US 2″x 4″ junction box, vertical and horizontal mounting of 75 x 75 mm, 86 x 86 and European round (ø71 for German and ø75 for French) junction boxes

NOTE: Use TR100 Deco plate for mounting if you are not using US 2 x 4” or UK 75 x 75 mm junction boxes. Refer to the Deco plate pocket guide (31-00657).

1. Install the junction box and perform the wiring as per its manufacturer’s instructions
2. Before mounting the wall plate, make sure that the Wall module wires are stripped to the length marked on the wall plate.
3. Pull the wires through the wiring opening of the wall plate and position the wall plate along the junction box to align the mounting holes. For junction box screw holes, refer to Fig. 8 .
4. Insert the screws into the holes and tighten them.

Wiring the Wallplate

IMPORTANT :

All wiring must comply with local electrical codes and ordinances.

Follow equipment manufacturer wiring instructions when available. A letter code is located near each terminal for identification.

CAUTION

Power must not be connected while wiring. Wiring a unit that is powered may result in electrical shock and/or equipment damage.

1. Connect wires to the terminals. Fig. 4  for terminal assignments and Table 4 on for terminal descriptions.
2. Loosen the terminal screw, and insert the solid wire (twist if it is stranded) into the wiring terminal hole directly.
3. Tight the terminal screw using the Phillips screwdriver (screw torque 0.4 Nm)
4. Push excess wire’s back into the hole.
5. Check for loose or frayed wire that may cause a short.

Mounting the display unit

After all wiring is completed, install the display onto the wall plate.

1. Hold the display unit in forward-tilted position and align the slots in the display unit with the protrusions on top of the wall plate.
2. Carefully pivot the display onto the wall plate to ensure proper engagement of pins with terminal blocks while ensuring engagement of protrusions and slots is maintained as shown in step 1.
3. Gently tighten the Security screw using a screwdriver by turning it in the clockwise direction (screw torque 0.1 Nm).

Dismounting the display unit

Dismounting the display unit onto the wall.

1. Gently loosen the security screw using a screwdriver by turning it in a counterclockwise direction.
2. Detach the bottom side by pulling the display unit out and detach the top side.
