1 HONEYWELL EXCEL 000 OPEN SYSTEM BEFORE INSTALLATION The Wireless Receiver (including the External Antenna) is capable of exchanging data with the following four types of room units: The RT00A00 Wireless Handheld Remote Control the T0A00 Wireless Wall Module with temperature sensor and setpoint; the T0A0 Wireless Wall Module with temperature sensor; and the T0B00 Wireless Wall Module for HAVC, light, and sunblind applications. The is suitable for use with up to eight rooms in which the aforementioned room units are in operation. The Wireless Receiver receives data from the room units at. MHz. WIRELESS RECEIVER INSTALLATION INSTRUCTIONS Communications The utilizes a free-topology transceiver (FTT0A) Link Power compatible LONWORKS network that allows daisy-chain, loop, and star network configurations or any combination thereof. Depending upon the LONWORKS network configuration used, one or two termination modules may be required (see Fig. 4). Different connections to the termination module are necessary, depending upon whether it is used in a single- or double-terminated network configuration. For more information, please see Mechanisms (ENB- 00GE). NOTE: The LONWORKS network is insensitive to polarity, eliminating installation errors due to miswiring STANDARDS AND NORMS The System complies with CE and EN and EN 0 4- as well as LONMARK Application Layer Guidelines Version.. IMPORTANT! It is recommended that devices be kept at room temperature for at least 4 hours before applying power to allow any condensation resulting from low shipping/storage temperatures to evaporate. Use in Combination with Legacy Devices The Wireless Receiver is suitable for use only with the T0A00, T0A0, T0B00 Wireless Wall Modules and the RT00A00 Wireless Handheld Remote Control. It cannot communicate with (but is likewise unaffected by) legacy devices (e.g. the T0A00, T0A0, T0B00, or the RT00A00). Set-Up Because of interference from other devices and the building structure, it is not possible to exactly define the wireless transmission range. For further details, see section "Installation of Wireless Systems" on page. Wire the 's communications network using level IV AWG or plenum-rated level IV AWG non-shielded, twisted pair, solid conductor wire. INSTALLATION See Fig. for outside dimensions and Fig. for sub-base mounting dimensions. The can be mounted in any orientation desired on a panel, wall, or onto a standard wall outlet box (see Fig. ). Power Input power provided must be 4 Vac (±0%), 0 or 0 Hz. The power consumption of the (including the connected active antenna) is VA. CAUTION Avoid electrical shock or equipment damage. Turn power OFF prior to connecting to or removing connections from any terminals. Use the heaviest gauge wire available, up to 4 AWG (. mm ), with a minimum of AWG (.0 mm ) for all power wiring.

Insert the wire in the required terminal location and tighten the screw to complete the termination. 4. Ensure that the wire entering the terminal block does not extend above the numbered face of the terminal block to avoid contact between the wires and the printed circuit board on the underside of the front cover (see Fig. ).

See also section " External Antenna Installation and Wiring" on page. Installation of Wireless Systems Due to the use of wireless technology for sending signals from transmitters i.e. room units to evaluation units (receivers) and the discontinuation of the use of electrical cable connections, there are some basic guidelines that must be followed during planning and installation. This information is intended to help both the planner with configuring the radio path and the system integrator/engineer or service technician with installation and troubleshooting.

4 WIRELESS RECEIVER Basics for Radio Signals in Buildings Radio signals are electromagnetic waves and as such diminish in strength on their way from the transmitter to the receiver, even when unobstructed. This drop in signal strength is inversely proportional to the square of the distance between the transmitter and the receiver. Table. Evaluating installation environment pathway unobstructed direct line of sight gypsum wall/wood brick wall/gas concrete reinforced concrete walls/ceilings typical range 0 m in passages, corridors, up to 00 m in halls m through max. 4 walls m through max. walls 0 m through max. wall/ceiling SIGNAL STRENGTH NOTE: Storage areas and elevator shafts should be regarded as obstructions. X DISTANCE SHEET METAL Fig. 0. Attenuation of signal strength with distance Physical Obstructions Beside this natural (distance-dependent) drop in signal strength, the presence of physical obstructions (e.g. walls, metallic objects, reinforcements in walls, metallized foils of thermal insulations or metallized heat-absorbent glass) located between the transmitter and the receiver can further weaken signal strength. This is referred to as "damping attenuation." It is true that radio waves can penetrate walls to an extent, but the resultant drop in signal strength is greater than with unobstructed propagation in the free field. Here are some examples of the blocking effect of different types of walls: Fig.. Obstruction of signal Likewise, avoid mounting the antenna and transmitter such that the radio waves travel along walls (see Fig. ). Table.

5 WIRELESS RECEIVER Distance to Other Interference Sources A distance between the room units and other (thirdparty) transmitters (e.g. GSM / DECT / wireless LAN) of at least m should be maintained. RD-PARTY TRANSMITTER X MIN. m XRD-PARTY TRANSMITTER Fig.. Distance to interference sources Further, a minimum distance of cm should be maintained between different components (i.e. External Antennas, Wall modules, and Handhelds; it is, of course, no problem if a External Antenna and a Wireless Receiver are closer together). Mounting Of Receiving Antenna Ideally, an external receiving antenna should be mounted at a central location in the room. If possible, the antenna should have a distance of min. 0. m (min. λ/4, example: at MHz cm) to the wall and 0. m to the ceiling. CEILING Troubleshooting Table.
