A minimum value of zero is also available. The maximum flow setting of the controller must be equal to or less than the selected capacity of the recirculating fan. On controls mounted by Price but supplied by others, the air volume ranges are guidelines only. * Selection of air flow limits below the listed values is not recommended. Stability and accuracy may not be acceptable at lower than recommended air flow limits. The actual performance will vary depending on the terminal unit controls supplied. Minimum air fl ow limit is based on min.02 in. w.g. differential pressure signal from air flow sensor (.04 in. w.g. for CP100 and CP200). Selection of air fl ow limits below the listed values is not recommended. Stability and accuracy may not be acceptable at lower than recommended air flow limits. The actual performance will vary depending on the terminal unit controls supplied. Maximum air flow limit is based on max 1.0 in. w.g. differential pressure signal from air flow sensor. F-449

The laboratory attained discharge and radiated sound power levels for each unit at various flows and inlet static pressures is presented in the Acoustical Data tables. This data is derived in accordance with AHRI Standard 880 and shows the 'raw' sound power levels of the terminal in the second through seventh octave bands with NO attenuation allowances. This data includes AHRI standard ratings which are on record with the Air-Conditioning Refrigeration Institute. Price also offers this Typical Application and Selection Guide to assist you in selecting the proper size and configuration of terminal for your needs. The attenuation allowances listed are based on values suggested in AHRI Standard , Appendix E. The suggested attenuation allowances are intended to be representative of typical jobsite constructions. If your conditions differ significantly from these it is recommended you utilize the sound power level data in the catalog and the procedures outlined in AHRI Standard If the NC levels listed in the Price catalog are being compared to other manufacturers catalogued NC information, a careful review of the other manufacturers attenuation allowances must be made. If allowances other than recommended AHRI Standard , Appendix E are used, a fair comparison of NC levels cannot be performed. F-451
