Honeywell W7070A2000 Installation instruction

HONEYWELL EXCEL 5000 OPEN SYSTEM

BEFORE INSTALLATION

The W7070A2000 ZAPP Wireless Receiver (including the ZAPP External Antenna) is capable of exchanging data with the following four types of ZAPP room units:

• The RT7070A2008 ZAPP Wireless Handheld Remote Control

• the T7270A2001 ZAPP Wireless Wall Module with temperature sensor and setpoint;

• the T7270A2019 ZAPP Wireless Wall Module with temperature sensor; and

• the T7270B2009 ZAPP Wireless Wall Module for HAVC, light, and sunblind applications.

The W7070A2000 is suitable for use with up to eight rooms in which the aforementioned ZAPP room units are in operation. The W7070A2000 ZAPP Wireless Receiver receives data from the ZAPP room units at 868.3 MHz.

STANDARDS AND NORMS

The ZAPP System complies with CE and EN 300 220-1 and EN 301 489-1 as well as L Guidelines Version 3.2.

IMPORTANT!

It is recommended that devices be kept at room temperature for at least 24 hours before applying power to allow any condensation resulting from low shipping/storage temperatures to evaporate.

Use in Combination with Legacy Devices

The W7070A2000 ZAPP Wireless Receiver is suitable for use only with the T7270A2001, T7270A2019, T7270B2009 ZAPP Wireless Wall Modules and the RT7070A2008 ZAPP Wireless Handheld Remote Control. It cannot communicate with (but is likewise unaffected by) legacy devices (e.g. the T7270A1001, T7270A1019, T7270B1009, or the RT7070A1008).

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 3.

ONMARK® Application Layer

LonWorks Communications

The W7070A2000 utilizes a free-topology transceiver (FTT10A) Link Power compatible L allows daisy-chain, loop, and star network configurations or any combination thereof.

Depending upon the L 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 “LonWorks Mechanisms” (EN1B0270GE51).

NOTE: The L

Wire the W7070A2000's LonWorks ® communications network using level IV 22 AWG or plenum-rated level IV 22 AWG non-shielded, twisted pair, solid conductor wire.

INSTALLATION

See Fig. 1 for outside dimensions and Fig. 2 for sub-base mounting dimensions. The W7070A2000 can be mounted in any orientation desired on a panel, wall, or onto a standard wall outlet box (see Fig. 3).

Power

Input power provided must be 24 Vac (±20%), 50 or 60 Hz. The power consumption of the W7070A2000 (including the

connected active antenna) is 2 VA.

Use the heaviest gauge wire available, up to 14 AWG (2.5 mm wiring.

Wiring Details

Fig. 5 illustrates the terminal assignments of the W7070A2000. Refer to job drawings for specific wiring diagrams. Connections to the W7070A2000 are made at an internal terminal block accessible beneath the front cover. No tools are required to remove the front cover.

1. Simply pull away the cover from the sub-base as shown in Fig. 6.

Use a minimum wire size of 20 AWG (0.5 mm output connections. The maximum length of all input / output cables is 20 m.

Wire to the terminal blocks as follows:

2. Strip 13 mm insulation from the conductor.

3. 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. 7).

ZAPP EXTERNAL ANTENNA

Each W7070A2000 is delivered together with a corresponding ZAPP External Antenna, to which it must be connected before it can receive signals from the ZAPP devices.

Install the ZAPP External Antenna only outside of metal housings (e.g. control cabinets).

Installation of Wireless Systems

Due to the use of wireless technology for sending signals from transmitters i.e. ZAPP 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.

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.

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:

Table 1. Blocking effect of different wall materials

material penetration

wood, gypsum, uncoated glass without metal 90...100% brick, pressboard 65...95% reinforced concrete with iron reinforcement 10...90% metal, aluminum pasting 0...10%

In actual practice, this means that the building material used in a building is of paramount importance for the evaluation of the transmitting range. For an evaluation of the environment, some standard values are listed:

NOTE: Storage areas and elevator shafts should be

regarded as obstructions.

Likewise, avoid mounting the antenna and transmitter such that the radio waves travel along walls (see Fig. 12).

Distance to Other Interference Sources

A distance between the ZAPP room units and other (thirdparty) transmitters (e.g. GSM / DECT / wireless LAN) of at least 1 m should be maintained.

Further, a minimum distance of 35 cm should be maintained between different ZAPP components (i.e. ZAPP External Antennas, ZAPP Wall modules, and ZAPP Handhelds; it is, of course, no problem if a ZAPP External Antenna and a W7070A2000 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. 0.1 m (min. λ/4, example: at 868 MHz ≈ 9 cm) to the wall and 0.5 m to the ceiling.
