* 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 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
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.
