Troubleshooting Tip #1: If the thermostat’s backlight is on continuously, but the Comm LED on the RF
Module is not continuously illuminated, bring the T1100RF Thermostat within five feet of the RF
Module. If the Comm LED still does not illuminate try adjusting the house code setting or check
batteries of the T1100RF thermostat.
Troubleshooting Tip #2: If the RF Module has been connected to a T1800 or T1900 thermostat that
is not compatible, the Comm LED will blink rapidly to indicate this error.
