When Installing This Product 1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition. 2. Check ratings given in instructions and on the product to ensure the product is suitable for your application. 3. Installer must be a trained, experienced service technician. 4. After installation is complete, check out product operation as provided in these instructions. INSTALLATION AND SETUP The following installation procedures are typically performed in the order listed: 1. Mounting — See “MOUNTING” below. 2. Wiring — See “WIRING” on this page. 3. Checkout — See page 11. 4. Programming — See page 14. 5. Scheduling (optional) — See page 30. Additional topics are: • Temperature sensor calibration begins on page 11. • Interface overview begins on page 12. • Setup (for advanced options) begins on page 17. • Summary menu begins on page 34. • Troubleshooting begins on page 34. MOUNTING This section describes the mounting procedures for the controller and temperature sensor(s). Controller Mounting IMPORTANT Avoid mounting in areas where acid fumes or other deteriorating vapors can attack the metal parts of the controller circuit board, or in areas where escaping gas or other explosive vapors are present. IMPORTANT The controller must be mounted in a position that allows clearance for wiring, servicing, and removal. Use a screwdriver to pry out only the knockouts that you will use. If mounting on DIN rail, be sure to remove the knockouts before mounting. See “Controller Wiring” on page 5 and Fig. 7 on page 6 for recommended knockout usage and locations. If you do not use an opened knockout be sure to cover it. Mount the controller on any convenient interior location using the four mounting holes provided on the back of the enclosure using #6 or #8 screws (screws are not provided and must be obtained separately). Use controller dimensions in Fig. 1 on page 2 as a guide. The controller may be mounted in any orientation. However, mounting in the orientation shown in Fig. 1 on page 2 permits proper viewing of the LCD display and use of the keypad. NEMA 4 Enclosure Mounting For models with NEMA 4 enclosures, ensure that waterproof wire/conduit fittings are used at the knockouts for all wiring attachments. Refer to Fig. 7 on page 6 for knockout locations. IMPORTANT For NEMA 4 enclosures, be sure to cover and seal all unused open knockouts. Temperature Sensor(s) Mounting and Location Temperature sensors may be located up to 1,000 feet (304 m) from the T775A/B/M controller. Refer to Table 3 on page 11 for calibration guidelines. The sensors may be mounted on a wall or panel for sensing space temperature, strapped to a pipe or inserted in an immersion well (see Fig. 2) for hot or cold water sensing, or taped to a standard cap or bulb holder for duct air sensing. To prevent moisture or condensation entering the sensor through the lead wire holes, mount the sensor with the lead wires exiting the bottom of the sensor. NOTES: 1. The included sensor is not designed for very wet applications. For immersion applications, an immersion well is used. 2. Heat conductive compound must be used in immersion wells. 3. Refer to the list of temperature sensors on page 2 for this type of installation . Fig. 2. Sensor Inserted in Immersion Well. NOTE: Multiple sensors may be parallel-series wired to sense average temperatures in large spaces. Refer to Fig. 3 on page 4. WIRING All wiring must comply with applicable electrical codes and ordinances, or as specified on installation wiring diagrams. Controller wiring is terminated to the screw terminal blocks located inside the device. The remainder of this section describes the temperature sensor wiring and the T775A/B/M controller wiring. SENSOR PLACED IN WELL IMMERSION WELL 1/2 NPT USE HEAT CONDUCTIVE COMPOUND M24470 T775A/B/M SERIES 2000 ELECTRONIC STAND-ALONE CONTROLLERS 62-0254—13 4 Wiring Connections Access To access the wiring connections, remove the two screws on the left side of the enclosure and gently swing open the top. Be careful to not stress the ribbon cables that connect the keypad and LCD display to the controller circuit board. Temperature Sensor Wiring CAUTION Electrical Shock Hazard. Can short equipment circuitry. Make sure that metal tube of sensor does not short against T terminals in wall-mounted case. IMPORTANT Poor wiring practices can cause erratic readings from the sensor. Avoid the following to ensure proper operation: • Do not route the temperature sensor wiring with building power wiring. • Do not locate the temperature sensor wiring next to control contactors. • Do not locate the temperature sensor wiring near electrical motors. • Do not locate the temperature sensor wiring near welding equipment. • Make sure good mechanical connections are made to both the sensor and the controller. • Do not mount the sensor with the lead wire end pointing up in an area where condensation can occur. If any of the above conditions cannot be avoided, use shielded cable. NOTE: Each T775 controller must be wired to its own sensor(s). However, a benefit of the T775 controller’s accuracy is that there is no more than a 2° F (-7° C) differential between any two T775 controllers. Multiple Parallel
