Compressor thermally protected internally.2. All wiring to the unit must comply with local codes.3. Neutral of 380/415-3-50 is required. Transformer is wired to 240 V (ORG) leadfor 415-3-50. For 380-3-50 switch ORG and (RED) leads at PB(2) and insulateORG lead. Transformer uses separate circuit breaker.4. FP1 thermistor provides freeze protection for water. When using anti-freezesolutions, cut JW3 jumper.5. Check installation wiring inforation for specific thermostat hook-up. Refer tothermostat installation instructions for wiring to the unit. Thermostat wiring mustbe ‘Class 1’ and voltage rating equal to or greater than unit supply voltage.6. 24-V alarm signal shown. For dry alarm contact, cut JW4 jumper, and drycontact will be available between AL1 and AL2.7. Transformer secondary ground via microprocessor board stand-offs andscrews to control box. (Ground available from top two stand-offs as shown.)8. Blower motor is factory-wired for medium and high speeds. For any othercombination of speeds, at the motor attach black wire to the higher of the twodesired speed taps, and the blue wire to the lower of the two desired speedtaps.9. Blower motor is factory-wired for high and low speeds. No other combination ofspeeds is available.E L3L2L1CB YEL24V RED(220V)BLKBLKG/YBLKBLKBLKBLKORG(240V)YEL ORWHTBRNYELBLKBLKBLKBLKL3L2L1T3T2T1CCCCG/YG/YBLKBLUREDBMHML678BR2T3T2T1654321BMCLUGT3T2T1CCPBBR1BR2TRANSYOGRCXIY1O/W2GRCAL1W1AL2AP3RCJW1LPG1234567891012HPLOCFP1RVCOP7P6CCG24VDCEH1EH2REDBLUBRNGRYGRYHPLOCFP1FP2BRNBRNORGYELVIO VIOVIOTXVNSBESDOVRHP2CRY2P1RRCOMNC2NO2COMNC1NO1 ACC1ACC2JW2FP2JW3FP1N.O.FP2CC123456781234567812345678COVIOYELCCA2 A1YRRED BLK*HWTSBLK*GRYBR2BR1BRNBRN10COMNO NCCOMNOCOM2 COM1R C S CS6 8YELBR1COMPRRELAYGRYYELBLUREDREDJW4AL2 DRYPBEarth (GRD)N (Neutral)Power supplyRefer to data plateUse copperconductors onlyComponent locationLugCompr.See note 8Typical heatpump T-statCompr.CoolingFan24 V a.c.CommonAlarmSee note 6 fordry alarm contactSee note 7AlarmrelaySeenote 6See note 5Ground lugTestpinsSeenote 4Low temp.Low temp.Relay Off OnRelayPM: Disable/enableUnit stage: 2/1T-stat: heat cool/heat pumpRV on 8/RV on 0Dehumid/normalNot usedBoilerless: Enable/disableBoilerless: 4.4°C/10°CDryDip switch package Dip switch packageOff OnDXMMicroprocessorcontrol logicSee note 7Fan enablerelayFanspeedrelayStatusTestFaultSee note 4TXV unitsCap. tubeunitsRV relayCompr.relayAcc1FunctionsAcc2FunctionsH:Hi fan/dehumidNot usedGS1 S2
