* These inputs (if installed) take the place of the default input on the specific channel according to schematic.
Parallel pins J5--- 1 = J2--- 6, J5--- 3 = J1--- 10, J5--- 5 = J1--- 2 are used for field --- installation.
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 50HCQ unit, the unit is supplied with
a supply- - air temperature (SAT) sensor (33ZCSENSAT).
This sensor is a tubular probe type, approx 6- - inches (12.7
mm) in length. It is a nominal 10- - k 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
1
codes). Drill or punch a /
2
Use two field- - supplied, self- - drilling screws to secure the
sensor probe in a horizontal orientation. See Fig. 34.

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 control is used with EconoMi$er2 (option
or accessory) for outdoor air management. The damper
position is controlled directly by the RTU Open control;
EconoMi$er2 has no internal logic device.
Outdoor air management functions can be enhanced with
field- - installation of these accessory control devices:
