Aspirator box is required for duct mounting of the sensor.33ZCASPCO2 --- Aspirator box used for duct--- mounted CO 2 room sensor.33ZCT55CO2 --- Space temperature and CO 2 room sensor with override.33ZCT56CO2 --- Space temperature and CO 2 room sensor with override and setpoint.Outdoor Air Temperature (OAT) Sensor — The OAT isfactory--mounted in the EconoMi$er2 (FIOP oraccessory). It is a nominal 10k ohm thermistor attached toan eyelet mounting ring.EconoMi$er2 — The PremierLink control is used withEconoMi$er2 (option or accessory) for outdoor airmanagement. The damper position is controlled directlyby the PremierLink control; EconoMi$er2 has no internallogic device.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 sensorRefer to Table 4 for accessory part numbers.Field connections — Field connections for accessorysensor and input devices are made at the 16--pole terminalblock (TB1) located on the control box top in front of thePremierLink control (See Fig. 26). Some input devicesalso require a 24--vac signal source; connect at CTBterminal R at “THERMOSTAT” connection strip for thissignal source. See connections figures on following pagesfor field connection locations (and for continuedconnections at the PremierLink board inputs).Table 5 provides a summary of field connections for unitsequipped with Space Sensor. Table 6 provides a summaryof field connections for units equipped with SpaceThermostat.Space Sensors -- The PremierLink controller isfactory--shipped configured for Space Sensor Mode. ACarrier T--55 or T--56 space sensor must be used. T--55space temperature sensor provides a signal of spacetemperature to the PremierLink control. T--56 providessame space temperature signal plus it allows foradjustment of space temperature setpoints from the face ofthe sensor by the occupants.2 3 4 5 61SW1SENBRN (GND)BLU (SPT)RED(+)WHT(GND)BLK(-) CCN COMSENSOR WIRINGC08201Fig. 27 -- T--55 Space Temperature Sensor WiringConnect T--55 -- See Fig. 27 for typical T--55 internalconnections.
