Use the ZFR-HPSST-0 High Power Survey tool to check signal strength and expected communications performance between the various field, WRZ Sensors, TEC31xx Series thermostat controllers, and the WRG Gateway. The ZFR-HPSST-0 survey tool is a special mode of the ZFR1831 Router used to test both ends of the wireless communication link. Both 100mW and 10mW transmission power signal strengths can be tested.
Note: Two ZFR-HPSST-0 are required to perform a site survey, one on each side of expected
transmission path.
If a site survey is deemed required, a checklist is available in the Wireless Best Practices Document (LIT-12013552) of information that can be used to determine how best to lay out the wireless network, how many devices are needed, and the best locations for installation.
