Table 25 — RTU Open Controller Inputs and Outputs
LEGEND
NOTES:
1. Safety Chain Feedback: 24 vac required at this terminal to pro-
vide “Run Enable” status. See Input/Output section for additional
instructions.
2. These inputs are configurable. If installed, they take the place of
the default input on the specific channel. See appropriate Input
Configuration 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, Opera-
tion 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 50HC**14 unit, the unit is supplied
with a supply-air temperature (SAT) sensor (33ZCSENSAT).
This sensor is a tubular probe type, approx 6-in. (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
shipping position. Remove the sensor for installation.
Re-position the sensor in the flange of the supply-air opening
or in the supply 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 orientation. See Fig. 62.
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.
