Temperature vs. Resistance for Nonlinear Sensor. Communications All wall modules (except the TR21 and TR21-A models) have a LONMARK® bus communications port. If needed, the jack plug must be removed in the field, and terminals 3 and 4 wired according to the installation instructions. The recommended wire size for the LONMARK® bus is Level IV, 22 AWG (0.34 sq.mm) plenum or non-plenum rated, non-shielded, twisted pair, solid conductor wire. Mount the wall module on an inside wall approximately 54 in. (1372 mm) from the floor (or in the specified location) to allow exposure to the average zone temperature. Do not mount the wall module on an outside wall, on a wall containing water pipes, or near air ducts. Avoid locations that are exposed to discharge air from registers or radiation from lights, appliances, or the sun. See “Cover Disassembly” on page 3. The wall module can be mounted on a wall, on a standard utility conduit box using No. 6 (3.5 mm) screws or on a 60 mm wall outlet box (see Fig. 3). When mounting directly on a wall, use the type of screws appropriate for the wall material.

Failure to follow proper wiring practices can introduce disruptive electrical interference (noise). Keep wiring at least one foot away from large inductive loads such as motors, line starters, lighting ballasts, and large power distribution panels. Shielded cable is required in installations where these guidelines cannot be met. Ground shield only to grounded controller case. 62-0267—09 M28126 2 TR21, TR22, TR23, AND TR24 WALL MODULES 3. 3 (76) 4. 1 1/2 (38) 9/16 (14) 1 3/16 (31) 7/8 (22) 4 13/16 (122) 70 NOTE: Wire the Lon connection (terminals 3 and 4) using Level IV 22 AWG (0.34 mm2) plenum or non-plenum rated, unshielded, twisted pair, solid conductor wire.

TEMPERATURE LIMIT SCREW POSITION (X12) NOTE: IF DESIRED, INSERT THE TWO SETPOINT SCREWS INTO THE DESIRED POSITIONS. NOTES: 1. 55 M25482 Fig. 4. Wall Module Subbase Dimensions in Inches (mm) and Temperature Limit Set Screw Locations (TR23 Shown). 2. 3. Cover Disassembly A snap-fit locking mechanism is used to attach the cover of the wall module to its subbase. To disassemble the cover from the subbase: 1. Insert a thin, flat blade screwdriver into each of the two slots at the bottom of the module to release the two locking tabs. See Fig. 2 on page 2. 2. Tilt the cover out and away from the subbase to release the top two locking tabs. 3. To change the dial (e.g. from Fahrenheit to Celsius) release the two tabs on the inside of the front cover and remove the old dial. 1/2 (13) The TR21 and TR22 models do not use DIP Switch S1 and S3. DIP Switch S1 is used only on the humidity models, TR21-H and TR23-H. Models TR21 and TR21-A use terminals 1 and 2 only. Model TR21-J uses terminals 1, 2, 3, and 4 only. 1. STRIP 1/2 IN. 2. TWIST WIRES TOGETHER WITH PLIERS (A MINIMUM OF THREE TURNS). Wiring Attach the wires from the device sensor terminals to the appropriate wall module terminals. See Table 1 on page 4. CONTROLLER OR WALL MODULE E-BUS CONNECTOR TERMINALS (13 MM) FROM WIRES TO BE ATTACHED AT ONE TERMINAL. 3. CUT TWISTED END OF WIRES TO 3/16 IN. (5 MM) BEFORE INSERTING INTO TERMINAL AND TIGHTENING SCREW. THEN PULL ON EACH WIRE IN ALL TERMINALS TO CHECK FOR GOOD MECHANICAL CONNECTION. M11413 Fig. 5. Attaching Two Wires (20 to 22 AWG) to Wall Module Terminals. CAUTION Improper Electrical Contact Hazard. Screw type terminal blocks are designed to accept no more than one 16 AWG (1.31 sq. mm) conductor. Connect multiple wires that are 16-18 AWG (1.31-0.82 sq. mm) with a wire nut. Include a pigtail with this wire group and attach the pigtail to the individual terminal block. Wiring Wall Modules Wire the terminal block as follows: 1. For single wires, strip 3/16 in. (5 mm); for multiple wires going into one terminal, strip 1/2 in. (13 mm) insulation from the conductor. 2. If two or more wires (20 to 22 AWG only) are being inserted into one terminal, twist the wires together before inserting. See Fig. 5. 3 Attaching the Cover When all wiring is complete, attach the cover of the Wall Module as follows: 1. Optional: For models with a temperature dial, insert the two setpoint screws into the inside of the cover to set the desired temperature range limit. See Fig. 4. 2. Press the cover straight down onto the subbase until it snaps into place. 3. For models with a temperature dial, insert the desired dial through the opening in the cover. Align the keyed shaft on the knob with the keyed slot into the fitting on the subbase, then press down until it snaps into place. 62-0267—09 TR21, TR22, TR23, AND TR24 WALL MODULES Wiring and DIP switch settings: See Table 1 to determine DIP switch positions and terminal usage for each controller.

The humidity sensing control mode is set with this 2-position DIP switch. Refer to Fig. 4 on page 3 for location of DIP switch S1. Table 2. Setpoint Values.

Override pushbutton operation. When Used With Excel 600/500/100/80/50 Controllers: The application engineer/programmer can program the override (bypass) and LED to operate in any manner desired. The override (bypass) input is a dry contact, normally open, momentary digital input when the wall module does not have a fan switch. When a fan speed switch (basically a series of resistances based on fan switch position) is present, the override button is an analog input. See Table 4 for resistances. When Used With T7350 Thermostat: TR21, TR21-A, TR21-H, TR22, TR23, and TR24 are the models compatible with the T7350 thermostat. When using with the T7350 thermostat be sure to use the relative +/- offset knob only. The Celsius and Fahrenheit knobs will not work properly with the T7350 Thermostat. 62-0267—09 Resistance (Ohms) Auto 6 When Used With Excel 600/500/100/80/50 Controllers: Excel 600/500/100/80 Controllers can be programmed so that the fan speed switch and override button function the way that the application engineer/programmer wants. See Table 8 for controller-programming resistances. Switch 1 on Dip Switch S2 adds 10k Ohms resistance when OPEN (for Excel 600-80 controllers) and removes it when CLOSED (for Excel 10 controllers).
