The RTU Open controller requires the use of a Bryant
space sensor. A standard thermostat cannot be used with
the RTU Open system.
Supply Air Temperature (SAT) Sensor —
On FIOP--equipped 580J units, 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 10--k ohm thermistor.
The SAT is factory--wired. The SAT probe is wire--tied to the
supply--air opening 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. 40.
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.
