15Deluxe DNOTES:1. Compressor and blower motor thermally protected internally.2. All wiring to the unit must comply with NEC and local codes.3. Transformer is wired to 460-v BLK/RED lead for 460-3-60 units. Trans-former is energy limiting or may have circuit breaker.4. FP1 thermistor provides low temperature protection for water. Whenusing antifreeze solutions, cut JW3 jumper.5. Refer to microprocessor control, LON, thermostat installation instruc-tions for wiring to the unit. Wire “N01” from LON to “Y1” Deluxe D whenmotorized valve is not used. Thermostat wiring must be Class 1 andvoltage rating equal to or greater than unit supply voltage.6. Factory cut JW4 jumper. Dry contact will be available between AL1 andAL2.7. Transformer secondary ground via green wire with yellow stripe from“C” terminal to control box.8. Blower motor is factory wired for medium and high speeds. For anyother combination of speeds, attach black wire to the higher of the twodesired speed taps at the motor, and attach the blue wire to the lower ofthe two desired speed taps.9. Blower motor is factory wired for high and low speeds. No other combi-nation is available.10. Optional LON wires. Only connect if LON connection is desired at thewall sensor.11. The 460-v units using an internal secondary pump will require a neutralwire from the supply side in order to feed the accessory with 265-v.Fig. 17 — 50PCH,PCV units with Deluxe D and LON Controller (460 V)LEGENDAL — Alarm Relay ContactsBM — Blower MotorBMC — Blower Motor CapacitorBR — Blower RelayCB — Circuit BreakerCC — Compressor ContactorCO — Sensor, Condensate OverflowFP1 — Sensor, Low Temperature Protection, Water CoilFP2 — Sensor, Low Temperature Protection, Air CoilHP — High-Pressure SwitchHPWS — High-Pressure Water SwitchJW1 — Clippable Field Selection JumperLOC — Loss of Charge Pressure SwitchLON — Local Operating NetworkMV — Motorized ValveMVES — Motorized Valve End SwitchNEC — National Electrical Code*Optional Wiring.P1 — Field Wiring Terminal BlockRVS — Reversing Valve SolenoidTRANS — TransformerTXV — Thermostatic Expansion ValveField Line Voltage WiringField Low Voltage WiringPrinted Circuit TraceOptional WiringRelay/Contactor CoilCondensate PanSolenoid CoilTemperature SwitchThermistorGroundWire NutRelay Contacts - N.C.Relay Contacts - N.O.Low Pressure SwitchHigh Pressure SwitchSplice CapCircuit Breakera50-8440
