Refer to the input configuration and accessory sections for more detail.

NOTE: Refer to RTU--MP Controls, Start-Up, Operation,

and Troubleshooting Instructions (Form 48--50H--T--2T)

for complete configuration of RTU --MP, operating

sequence s and troubl eshooting information. Refer to

RTU--MP 3rd Party Integration Guide for details on

configura tion and troubleshooting of connected networks.

Have a c opy of these ma nuals available at unit start--up.

The RTU--MP controller requires the use of a Bryant

space sensor. A standard thermostat cannot be used with

the RTU--MP system.

Supply Air Temperature (SAT) Sensor

On FIOP--equipped 580J unit, the unit is supplied with a

supply--air temperat ure (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. See

Table 16 for temperature--resistance characteristic.

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 fla nge or duct.

Use two field--supplied, self--drilling screws to secure the

sensor probe in a horizontal orientation. (See Fig. 43.)

Outdoor Air Temperature (OAT) Sensor

The OAT is factory--mounted in the EconoMi$er 2 (FIOP

or accessory). It is a nominal 10k ohm thermistor attached

to an eyelet mounting ring. See Table 16 for

temperature--resistance characteristic.
