Table 25 — RTU Open Controller Inputs and Outputs
LEGEND
(1)Safety Chain Feedback: 24Vac required at this terminal to provide
“Run Enable” status. See Input/Output section for additional instruc-
tions.
(2)These inputs are configurable. If installed, they take the place of
the default input on the specific channel. See appropriate Input Con-
figuration Section for wiring and setup instructions.
(3)Parallel pins J5—1 = J2—6, J5—3 = J1—10, J5—5 = J1—2 are
used for field installation.
(4)Refer to the input configuration and accessory sections of the
RTU Open Multi-Protocol Controller Controls, Start-Up, Operation
and Troubleshooting manual for more detail.
The RTU Open controller requires the use of a Carrier space
sensor. A standard thermostat cannot be used with the RTU
Open system.
SUPPLY AIR TEMPERATURE (SAT) SENSOR — On
FIOP-equipped 50TC unit, the unit is supplied with a supply-
air temperature (SAT) sensor (33ZCSENSAT). This sensor is a
tubular probe type, approx 6-inches (152 mm) in length. It is a
nominal 10k ohm thermistor.
The SAT is factory-wired. The SAT probe is wire-tied to the
supply-air opening (on the horizontal opening end) in its ship-
ping position. Remove the sensor for installation. Re-position
the sensor in the flange of the supply-air opening or in the sup-
ply air duct (as required by local codes). Drill or punch a
1 /
2
-in. hole in the flange or duct. Use two field-supplied, self-
drilling screws to secure the sensor probe in a horizontal orien-
tation. See Fig. 76.
OUTDOOR AIR TEMPERATURE (OAT) SENSOR —
The OAT is factory-mounted in the EconoMi$er2 (FIOP or
accessory). It is a nominal 10k ohm thermistor attached to an
eyelet mounting ring.
ECONOMI$ER2 — The RTU Open controller is used with
EconoMi$er2 (factory-installed option or field-installed acces-
sory) for outdoor air management. The damper position is con-
trolled directly by the RTU Open controller; EconoMi$er2 has
no internal logic device.
