Performing A Site Survey - Honeywell TB7200 Series Wireless Installation & Integration Reference Manual

WIRELESS INSTALLATION & INTEGRATION REFERENCE GUIDE FOR TB7200/TB7300/TB7600 SERIES THERMOSTATS

PERFORMING A SITE SURVEY

This section provides information to complete a site survey.
Tools Needed
• WEBs 2xx, 6xx or 7xx controller
• TB-VWG-APP-1014 Wireless communication card
• 2 to 5 TB7xxx thermostats or repeaters
• 24 Vac power supplies for controller and thermostats/repeaters
• Site floor plan drawing
Preparing for the Site Survey
Prepare the following prior to going to the job site to do a site survey.
1. Create a site drawing of proposed locations for all wireless devices like the floor plan shown in Fig. 6.
2. Add and configure a wireless communication card to a WEB-2xx, WEB-6xx, or WEB-7xx controller. See the Programming
section for more information.
NOTE: To ensure a proper survey, Honeywell recommends using ONLY channels 15 or 25 to avoid network interfer-
ence with 802.11 Wi-Fi devices in the 2.4GHz spectrum range. Begin by setting BOTH devices to the SAME
channel & PAN ID.
3. Add two to five wireless thermostats and/or wireless repeaters to the controller using the Workbench. Be sure to configure
all thermostats/repeaters with the same PAN ID and Channel as the wireless communication card.
NOTE: Using five thermostats/repeaters for the site survey will save time in completing the survey. If you have fewer than five,
you may need to shut down and move the controller several times to test the number of hops at the site.
Best Practices When Performing the Site Survey
• Always hold the thermostat vertically to ensure proper measurements. The thermostats antenna is designed for optimal
horizontal distance penetration. Holding the thermostat horizontally will dramatically lower the range of connectivity.
• Hold the thermostat at the location where you would like to install it. The closer the thermostat is to the actual installation
location of the thermostat, the more accurate the survey results will be.
• Do NOT stand directly in between the thermostat and the controller while measuring. Your body will interfere with transmission
signals. Always stand out of line of sight to avoid interfering with the signal readings.
• To ensure accurate readings, ALWAYS hold the thermostat near the bottom. Do not hold it up higher, as you may cover the
antenna (Fig. 8).
NOTE: Always place thermostat as close as possible to the final location of the wireless thermostat once installed.
