Indoor Control Wiring
IMPORTANT: DO NOT place more than one wire under any single
communication terminal screw (there are four communication terminal
screws). If more than one wire must be connected to a terminal screw,
attach only the terminal end of a one-wire pigtail no longer than 6 in.,
and use a wire connector to connect the other end of the pigtail to the
other wires. Failure to do this results in nuisance communication error
faults. See Figure 13.
