The RTU- - MP controller requires the use of a Carrier
space sensor. A standard thermostat cannot be used with
the RTU- - MP system.
Supply Air Temperature
FIOP- - equipped 50TCQD 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 /

Use two field- - supplied, self- - drilling screws to secure the
sensor probe in a horizontal orientation. See Fig. 28.
Outdoor Air Temperature (OAT) Sensor - - The OAT is

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

Field Connections - - Field connections for accessory
sensors and input devices are made the RTU- - MP, at plugs
J1, J2, J4, J5, J11 and J20. All field control wiring that
connects to the RTU- - MP must be routed through the
raceway built into the corner post as shown in Fig. 22.
