the impurities from the drain pan mid coil dust or dirt create theconductance. A second ground wire with appropriate terminalto the drain pan cml be used with file control to replace the aircoil ground path. The condensate sensor cml also be any opencontact that closes upon a fault comlection.Table 6 -- Thermistor Calibration PointsMINIMUM MAXIMUM NOMINALTEMP (F) RESISTANCE RESISTANCE RESISTANCE(ohm) (ohm) (ohm)78.5 9,523 9,715 9,61977,5 9,650 9,843 9,74676.5 10,035 10,236 10,13575.5 10,282 10,489 10,38533,5 30,975 31,598 31,28532.5 31,871 32,512 32,19031.5 32,653 33,310 32,98030,5 33,728 34,406 34,0651.5 80,624 82,244 81,4300.5 83,327 85,002 84,1600.0 84,564 86,264 85,410Deluxe D Control -- The Deluxe D control includes allof the control operations above in addition to the followingadvanced operations:LED INDICATORS -- There are 3 LED indicators on theDeluxe D control. See Table 7 for indicatol.'s.Status LED -- Status LED indicates the current status or modeof the Deluxe D control. The status LED light is green.Test LED -- Test LED will be activated any time the DeluxeD control is in Test mode. The test LED light is yellow.Fault LED -- Fault LED light is red. The fault LED will al-ways flash a code representing the last fault in memory. If thereis no fault in memory, the fault LED will flash code 1 on theand appear as 1 fast flash alternating with a 10-second pause.See Table 7.90.080.070.0600L50.08 40.030.0cE 20.010.00,00.0 20.0 40.0 60.0 80.0 100,0 120.0 140.0Temperature (degF)Fig. 8 -- Thermistor Nominal ResistanceEXTENDED COMPRESSOR OPERATION MONITOR --ff the compressor has been on for 4 continuous hours the con-trol will automatically turn off the compressor relay and waitthe short cycle time protection time.
