Figure 7: Thermostat to Network Connection
The L
ONWORKS network requires proper termination
and biasing at the end of a segment (a segment is a
physically continuous length of wire). The thermostat is
not equipped with the ability to provide this termination;
therefore, it cannot be located at the physical end of a
L
ONWORKS network segment unless a terminator is
attached. Refer to L
ONWORKS Network Layout
Technical Bulletin (LIT-1162150) for end-of-line
solutions.
