your home using the handheld T1100RF Wireless Thermostat.*

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.
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.
