BASIC INITIAL DESIGN AND DEPLOYMENT
CONSIDERATIONS
Proper design considerations need to be addressed prior to any installation of a WEBs-AX controller with a the wireless
communication card (TB-VWG-APP-1014) and related wireless thermostats.
1. To properly avoid network interference with 802.11 Wi-Fi devices in the 2.4GHz spectrum range, Honeywell
recommends the use of 802.15.4 channels 15 or 25 only. 802.11 Wi-Fi transmissions overlap and may interfere
with other channel selection allowed by 802.15.4 (Channels 11 to 26).
2. Maximum distance between each node (thermostat or repeater) should be:
•Clear line of sight distance between 2 nodes should be under 100 feet (30M)
•Non-line of sight distance for typical drywall partitions made with metal stud frame should be under 30 feet
(10M)
3. Ensure that the minimum distance between any Honeywell ZigBee node and any Wi-Fi devices (wireless routers,
wireless adapters, lap-tops using wireless networks, etc.) is at least 3 feet (1 M) and preferably 10 feet (3 M) or
more.
4. Ensure that at least one thermostat is within 30 feet of the WEBs-AX controller with wireless communication card
for every cluster of 10 thermostats installed.
5. Always try to locate the WEBs-AX controller near the center of all associated wireless thermostats, if possible.
6. Always try to locate the WEBs-AX controller near or in line of sight to as many wireless thermostats as possible.
7. Try to avoid metal, brick walls or concrete obstructions between wireless devices as much as possible.
8. Make sure the antenna on the WEBs-AX controller is always perpendicular to the floor.
9. Avoid placing the WEBs-AX controller and thermostats near metal or enclosed in metal boxes. If the WEBs-AX
controller needs to be installed inside a metal cabinet, use the remote antenna accessory (TB-RA-1014).
