See Input/Output section for additional instructions.(2) These inputs are configurable. If installed, they take the place of the default input on the specific channel. See appropriate Input Configuration Section for wiring and setup instructions.(3) Parallel pins J5--- 1 = J2--- 6, J5--- 3 = J1--- 10, J5--- 5 = J1--- 2 are used for field--- installation.(4) Refer to the input configuration and accessory sections of the RTU Open Multi ---Protocol Controller Controls, Start ---Up, Operation and Troubleshooting manual for more detail.The RTU Open controller requires the use of a Carrierspace sensor. A standard thermostat cannot be used withthe RTU Open controller system.Supply Air Temperature (SAT) Sensor —On FIOP--equipped 50TCQ unit, the unit is supplied with asupply--air temperature (SAT) sensor (33ZCSENSAT). Thissensor is a tubular probe type, approx 6--inches (152 mm) inlength. It is a nominal 10--k ohm thermistor.The SAT is factory--wired. The SAT probe is wire--tied tothe supply--air opening (on the horizontal opening end) inits shipping position. Remove the sensor for installation.Re--position the sensor in the flange of the supply--airopening or in the supply air duct (as required by localcodes). Drill or punch a 1 / 2 --in. hole in the flange or duct.Use two field--supplied, self--drilling screws to secure thesensor probe in a horizontal orientation. See Fig. 49.Outdoor Air Temperature (OAT) Sensor —The OAT is factory--mounted in the EconoMi$erR2 (FIOPor accessory). It is a nominal 10k ohm thermistor attachedto an eyelet mounting ring.EconoMi$er2 —The RTU Open controller is used with EconoMi$er2(option or accessory) for outdoor air management. Thedamper position is controlled directly by the RTU Opencontroller; the EconoMi$er2 unit has no internal logicdevice.Outdoor air management functions can be enhanced withfield--installation of these accessory control devices:Enthalpy control (outdoor air or differential sensors)Space CO2 sensorOutdoor air CO2 sensorField ConnectionsField connections for accessory sensors and input devicesare made the RTU Open controller, at plugs J1, J2, J4, J5,J11 and J20. All field control wiring that connects to theRTU Open controller must be routed as shown in Fig. 38.This routing provides the UL required clearance betweenhigh-- and low--voltage wiring. Connect to the wires to theremovable PCB connectors and then reconnect theconnectors to the board.
