Maintenance
No routine maintenance is required, however protec-
tion from extremes of humidity and dirt is recom-
mended. Careful installation will also ensure long
term reliability and performance.
NOTE: For more information about the CEP-4000/
CTE-1004 example, see the CEP-4000
Series VAV Flow Controllers-Actuators
Application Guide.
NOT E: The “C” terminal does NOT denote
Common/Neutral. “C” is the phase side
of the 24 VAC (and is also the side the
contactors have in “common”). “9” is the
neutral side. Triac stages 1 through 3 are
for 24 VAC loads only.
NOTE: “T” input
is 0 to
6 VDC.
(See the
Thermostat
Signal
chart.)

Troubleshooting
• Check the wiring.

tral). (See the chart on the previous page.)
