To check the Comfort Control Center, first verify the ON/OFF
switch is in the ON position. Next, verify DC volts (10 to 30) and
polarity are correct (see Sec. 4). Then do a reset procedure
(see Sec. 1M). If the Comfort Control Center still does not
illuminate when depressing any selector button or the liquid
crystal display does not read (See Sec. 1), replace it. If the
correct function does not show on the liquid crystal display,
verify configuration is correct (see Sec. 2) before replacing the
Comfort Control Center.
2. CABLE ASSEMBLY
A flat telephone extension cable must be routed from the unit
to the Comfort Control Center. It must be 26 gauge, stranded
copper wire, four (4) conductor (yellow, green, red and black).
The cable must be terminated with a four (4) position tele-
phone RJ-11 connector.
NOTE: DO NOT USE A PRE-MADE TELEPHONE
EXTENSION CABLE. THE POLARITY OF THE CON-
NECTORS IS REVERSED AND WILL CAUSE A FAIL-
URE OF THE SYSTEM.
The cable assembly should be made in the following
manner:
Cut the modular cable to the desired length. When cutting,
make sure ends are cut straight, not diagonally. Next, use an
RJ11 connector crimping tool.
Use the stripper section of the tool's blade to remove the outer
insulation from each end of the cable. Be careful not to remove
or break the colored insulation on the inner conductors.
NOTE: Fully insert the cable into the stripper slot, holding
cable in one hand and tool in the other hand. Squeeze
down on tool and pull away. This will remove the correct
amount of outer insulation for insertion into RJ-11 modular
plug.
Now you are ready to insert the prepared cable into the RJ-11
modular plug. When inserting cable into plug, you MUST be
sure that the black wire is on your left as you look at the top of
the plug (with the spring clip facing you) and that the conduc-
tors are flush with the tip of the plug and touching the small
teeth-like gold conductors. Insert the RJ-11 modular plug with
the cable into the tool's cavity, squeeze down to the STOP and
hold for a few seconds. This completes connections for one
end of the cable. To prepare the other end of the cable, repeat
this procedure.
NOTE: Be sure polarity is the same on each plug. Example:
Black on left (viewing plug from top, spring clip side).
