The RF Module and the T1100RF that are contained in the T1119RF package arrive
from the factory preset to House Code zero. For this reason, it is not necessary to
change the house codes of the T1100RF and RF Module for proper operation.
However, if interference is encountered, the house codes may be changed as
instructed below. For more information regarding the T1100RF, please consult
the T1100RF Owner’s Manual.

To set the House Code on the RF Module, add all of the switches that are in the
ON position. The numbers of each switch are printed on the plastic next to the
opening for the switches. This total equals the House Code number. Please
disregard the numbers on the switch itself.

After the dip switches have been set, plug the RF Module
into the base of the thermostat.

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.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
