INSTALLER TESTS
Use the installer tests to check out the system:
• Equipment Test: Tests the heating, cooling, fan, and IAQ
systems. The test allows you to manually call for each

properly. Any minimum off timers are ignored during the
system test. You can test the following equipment:
—Heat
—Em Heat
—Cool
—Fan
— Humidification
— Dehumidification
— Ventilation
— Economizer
— Time of Day
• Wireless Signal Strength Test: Run this test to verify that
the thermostat can communicate properly in the installed
location. If not, the thermostat may have to be moved. The
test measures the signal strength between the
— Thermostat and the Equipment Interface Module (in
non-zoned applications)
— Thermostat and the TrueZONE Wireless Adapter (in
zoned applications)
