NOTE: Refer to Form
NOTE: The sensor must be mounted in the discharge airstream downstream of the cooling coil and any heating devices. Be sure the probe tip does not come in contact with any of the unit’s heater surfaces.
Outdoor Air Temperature (OAT) Sensor —
The OAT is
EconoMi$er2 —
The PremierLink control is used with EconoMi$er2 (option or accessory) for outdoor air management. The damper position is controlled directly by the PremierLink control; EconoMi$er2 has no internal logic device.
Outdoor air management functions can be enhanced with
Enthalpy control (outdoor air or differential sensors) Space CO2 sensor
Outdoor air CO2 sensor
Refer to Table 3 for accessory part numbers.
