Procedure

  1. Determine the sensor placement.

    In addition to the typical thermostat and temperature control location considerations, follow these guidelines for locating a sensor in wireless applications:

    • Locate the sensor on the same building level as the nearest FX-ZFR1811 or FX-ZFR Pro Series Router or FX-WRZ78xx Receiver.
    • For best signal transmission, locate the sensor at least 51 mm (2 in.) away from any metal obstructions.
    • Wherever possible, locate the sensor in the direct line of sight to the FX-ZFR or FX-ZFR Pro Series Router or FX-WRZ78xx Receiver. Signal transmission is best if the path between the sensor and the router or receiver is as direct as possible. Line of sight is desirable but not required, as long as the path is not blocked by large metal objects.
    • Avoid metal obstructions (including equipment rooms and elevator shafts) and concrete or brick walls between the sensor and the FX-ZFR or FX-ZFR Pro Series Router or FX-WRZ78xx Receiver.
    • Do not locate the sensor in recessed areas or metal enclosures.
    • In mesh network applications, install the sensor within range of two or more FX-ZFR or FX-ZFR Pro Series Routers. Redundancy in the layout provides the best reliability in wireless installations.
    • Do not mount the sensor closer than 2 ft (0.61 m) or farther than 100 ft (30 m) from the FX-ZFR or FX-ZFR Pro Series Router or 150 ft (45 m) from the FX-WRZ78xx Receiver.
    • The recommended indoor line-of-sight transmission range between the sensor and the FX-ZFR or FX-ZFR Pro Series Router is50 ft (15 m).
    • Mount the sensor on an interior wall where it is easily accessible, at least 55 in. (1.4 m) above the floor, in an area where the temperature is representative of the entire controlled space.
    • Avoid enclosed or recessed locations and locations behind curtains, doors, or other obstructions to the controlled space.
    • Avoid locations near entry foyers, doors, windows, supply air ducts, and pipes.
    • Avoid locations that are exposed to drafts, direct sunlight, and other sources of heat or cooling.
    • Avoid locations where the sensor could be exposed to excessive vibration.
  2. Measure the distance from the head wall system to the desired location of the sensor placed on the bed.

    Note: Be sure the cable is long enough to be able to attach the sensor to the wall. See Attaching the Tether Cable to the FX-WRZ Handheld Temperature Room Sensor and Mounting the FX-WRZ Handheld Temperature Room Sensor for more information.
