16CONNECT THE BLUE WIRE TO:FAN MOTORMEDIUM FACTORY SETTINGH FOR HIGH SPEED FANM FOR MEDIUM SPEED FANL FOR LOW SPEED FANH M LBLU3.8.4 - PSC (permanent split capacitor) blower speedselectionAll water-source heat pumps are factory-set to deliver rated airflow at nominal static (37 Pa) on medium speed. Where higherstatic is needed, high speed can be utilised (100 to 125 Pa). Lowspeed will deliver approximately 85% of rated air flow (25 Pa).The PSC blower fan speed can be changed on all units byswapping wires connected to the relay contacts that control thefan (see Table 4 and Fig. 14).NOTE: Available air flow for all units is shown in Table 4.Fig. 14 - 50RHE blower speed selectionTable 4 - Fan performance50RHE blower performance50RHE Nominal Minimum Fan Air flow, l/sair flow air flow speed External static pressure, Pal/s l/s 0 25 50 75 100 125006 81 61 High 133 123 112 89 78 -Medium 110 99 87 68 - -Low 98 90 75 60 - -009 113 85 High 165 151 142 118 99 -Medium 160 146 127 113 94 -Low 151 137 123 109 90 -012 140 104 High 170 165 151 137 123 109Medium 165 151 142 127 118 -Low 146 137 127 118 104 -015 212 160 High 345 316 288 250 198 -Medium 321 302 274 241 189 -Low 293 278 255 222 179 -019 264 198 High 326 311 283 250 203 -Medium 302 288 260 227 189 -Low 293 269 245 217 179 -024 307 231 High 396 368 335 302 260 -Medium 387 359 326 297 255 -Low 368 340 311 278 231 -030 349 264 High 529 496 463 425 378 330Medium 510 477 448 415 368 326Low 458 439 406 378 340 297036 437 326 High 614 576 579 463 415 373Medium 580 543 488 434 392 349Low 505 472 429 387 349 -042 530 396 High 743 691 629 566 501 435Medium 637 593 539 485 429 -Low 498 463 421 - - -048 630 472 High 793 738 672 604 535 464Medium 777 723 658 592 524 455Low 762 709 645 580 514 446High static048 630 472 High - - - 757 668 552Medium - - 787 710 623 529Low - 797 748 690 612 516060 790 595 High 896 866 833 796 755 710Medium 818 803 779 747 707 658Low 748 731 709 683 653 618LegendShaded areas are below minimum air flow.
