Basic Design And Deployment Considerations - Honeywell TB7200 series User Manual

ZIGBEE WIRELESS SURVEY TOOLKIT FOR TB7200/TB7300/TB7600 SERIES THERMOSTATS
BASIC DESIGN AND
DEPLOYMENT
CONSIDERATIONS
Proper design considerations need to be addressed prior
to any installation of a WEBs-AX controller with a
Honeywell wireless communication card and related
wireless thermostats.
• Honeywell recommends using a per floor horizontal
architecture vs. a vertical one. Transmitting from one
floor to the other may be possible in certain
applications (such as going through stairways), but the
design and optimization of the thermostat antenna is
designed for optimal horizontal distance penetration
and not a vertical one. As such, be prepared to use AT
LEAST ONE WEBs-AX controller and wireless
communication card per floor.
• Please note that radio transmissions CANNOT travel
through steel. If floors are constructed with steel joists
or other steel materials it is highly unlikely that the
wireless thermostat transmissions will be successful
between floors.
Clear line of sight deployment
• To avoid network interference with 802.11 Wi-Fi
devices in the 2.4GHz spectrum, Honeywell
recommends the use of 802.15.4 channels 15 and 25
ONLY. 802.11 Wi-Fi transmissions overlap and may
interfere with other channel selections allowed by
802.15.4 (Channels 11 to 26).
• With clear line of sight deployment (no physical
obstacles between 2 communicating thermostats), the
maximum distance between each thermostat is 100
feet (30 meters). See Fig. 4 .
NOTE: LINE OF SIGHT DISTANCE BETWEEN TWO NODES IS A MAXIMUM
OF 100 FEET (30 M).
Fig. 4. Line of sight distance between two nodes is a
maximum of 100 feet (30 M).
Non-clear line of sight deployment
• The maximum non-clear line of sight distance between
thermostats for gypsum wall partitions which may
include metal stud framing is a maximum of 50 feet (15
meters). See Fig. 5.

NOTE: MAXIMUM 50 FEET (15 M) BETWEEN 2 THERMOSTAT NODES.
Fig. 5. Non-clear line of sight distance between two
thermostat nodes is a maximum of 50 feet (15 M).
• In order to avoid interference from other wireless
devices, such as wireless routers, wireless adapters or
laptops using wireless networks, etc., ensure that a
minimum distance of 3 feet (1 meter) is maintained
between any Honeywell wireless device and any Wi-Fi
devices. A distance of 10 feet (3 meters) or more is
preferred when possible (Fig. 6).
MINIMUM 3 FEET (1 M) BETWEEN WI-FI
EQUIPMENT AND HONEYWELL WIRELESS DEVICES
PREFERABLY 10 FEET (3 M) OR MORE BETWEEN WI-FI
EQUIPMENT AND HONEYWELL WIRELESS DEVICES

• Ensure that at least one thermostat is within 50 feet
(15 M) of the controller with wireless card for every
cluster of 10 thermostats installed. WEB-2xx
controllers have a recommended max of 30 wireless
thermostats per controller. If 30 thermostats are
installed, three thermostats should be installed within
50 feet of the controller with wireless card. WEB-6xx
and WEB-7xx controllers have a recommended max of
50 wireless thermostats per controller. If 50
thermostats are installed, five thermostats should be
within 50 feet of the controller with wireless card. (Fig.
5 and Fig. 6)
• Always install the controller with wireless card closest
to the center of all associated wireless thermostats.
