circuitry. Disconnect power supply before installation. RESISTANCE (OHMS) Location Locate the remote sensor about 5 ft (1.5m) above the floor on an inside wall where it will be affected by freely circulating air at average room temperatures. Mounting 1. Loosen the cover locking screw with the Allen wrench provided and remove the device cover. 2. Run wire to the selected location. 3.

Make connections to the T7047 (see the Wiring section). 5. Select the proper screws for the application. Four Fig. 4. T7047C1025 Remote Sensor resistance mounting screws are provided: change with change in temperature. a. Two self-tapping type for wall mounting. b. Two for outlet box mounting. 6. If air drafts occur through the wall opening, eliminate with suitable material. 7. Fasten the T7047 on the wall or outlet box with screws through the mounting holes in the device. (See Fig. 2.) 8. Replace the cover and tighten the cover locking screw.

T7047H1008 Remote Sensor resistance change with change in temperature. Wiring IMPORTANT All wiring must agree with applicable codes, ordinances and regulations. Fig. 8 through 16 show schematics and typical connections. Also refer to instructions supplied with other system components. IMPORTANT To avoid electrical interference, which can cause erratic performance, keep wiring runs as short as possible and do not run wires adjacent to the line voltage electrical distribution systems. Use shielded cable (Belden type 8762 or equivalent for 2-wire and Belden type 8772 or equivalent for 3-wire). The cable shield must be grounded only at the controlled equipment case. Fig. 6.
