Compressor thermally protected internally.2. All wiring to the unit must comply with local codes.3. Transformer is wired to 240 V (ORG) lead for 240-1-50 units, switch RED andORG leads to PB(1) and insulate ORG lead for 220-1-50.4. FP1 thermistor provides freeze protection for water. When using anti-freezesolutions, cut JW3 jumper.5. Check installation wiring information 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.Sizes 015-060GEarth (GRD)N (Neutral)Start assist(when needed)CompressorPower supplyRefer to data plateUse copperconductors onlyPowerdistributionblockSee note 3Component locationTypical heatpump T-statCompr.CoolingFan24 V a.c.CommonAlarmSee note 6 fordry alarm contactSizes 006, 009, 012See note 7TestpinsSeenote 4Low temp.Low temp.AlarmrelaySeenote 5See note 8See note 5Relay 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°CDip switch packageOff OnDXMMicroprocessorcontrol logicSee note 7Acc1FunctionsAcc2FunctionsH:Hi fan/dehumidNot usedFan enablerelayFanspeedrelayStatusTestFaultSee note 4TXV unitsCap. tubeunitsRV relayCompr.relayS1 S2Dip switch package
