Network Wiring
Network Cable Fitting Locations
in the enclosure cover. Carefully follow the wiring diagrams shown below when connecting the network. The network cable must
"daisy-chain" from controller to controller with the last controller having a only single cable attached. No more than two (2)
network cables are allowed inside any controller box. Any other configuration will NOT function correctly.

Final Inspection and Cover Reassembly
Verify all wiring with wiring diagrams. Confirm there are no loose strands of wire or exposed shielded cables. Carefully insert the
interconnect wire harness plug into mating socket located on the Power/Relay circuit board. Reinstall the cover while verifying all
cables and wires are completely within the enclosure and are not interfering with the enclosure seal. Carefully tighten the four (4)
large plastic cover screws evenly. Do not over tighten.
Sensor Wiring
The temperature sensor probe assembly is pre-wired at the factory. The temperature sensor probe wiring connections are made
to the display circuit board mounted in the enclosure cover. If sensor removal or replacement is required, be sure to follow the
wire color designations printed on the circuit board when reconnecting the sensor.
To maintain enclosure watertight integrity, the low-voltage network cable(s)
must either be placed inside a separate low-voltage-only 4X liquid-tight
rated ½" conduit or be secured with a PG7 type 4X liquid-tight rated strain
relief (one for each cable). Under no circumstances can low voltage
(network/sensor) wiring and line voltage control wiring be combined inside
the same conduit. It is more convenient to drill the additional cable/conduit
fitting holes before mounting the enclosure. Do NOT use a twist-type drill
bit to fabricate holes as they will not drill smooth holes and may damage
the Controller enclosure. A hole saw or step-bit will give satisfactory
results.
Remove all power sources before opening the TC-2000 enclosure. The
network wiring connections are made to the display circuit board mounted
