결론: 예, but there are two approaches — directly replace the original control board, or use the PC4001 (PLC) to fully rewrite the control program.
The Pentair PASRW130S-U-T3-60 is a 55kW swimming pool / industrial heat pump / water chiller unit (with heat recovery, T3 operating condition, 60Hz model). It comes factory-fitted with a dedicated PC4001 heat pump controller (not the Phoenix Contact RFC 4001 PLC). Your question is: Can the Phoenix Contact RFC 4001 (PLC) be programmed to control this 55kW unit?
- 첫 번째, distinguish between the two “PC4001” 단위 (비판적인)
Original PC4001 (dedicated heat pump board)
The factory-installed controller for your unit: dedicated temperature control board for swimming pools and heat pumps
내장된 기능: 냉각 / 난방 / defrosting / 4-way valve / 팬 / 워터 펌프 / protection logic
인터페이스: temperature probes (NTC/PT1000), high/low pressure switches, water flow switch, 압축기, 팬, 4-way valve, 워터 펌프, 알람 출력
Cannot be programmed with PLC software; parameters can only be set via the control panel or RS485 communication
Phoenix Contact RFC 4001 (PLC)
General-purpose PLC, requires matching I/O modules
Can fully replace the original PC4001 and control this 55kW unit with custom programming

Condenser fans (1–2 units)
Evaporator / 워터 펌프
4-way valve (cooling/heating switching)
Water flow switch, high/low pressure protection, oil pressure differential, 방전온도, anti-freeze protection
센서:
Inlet water temperature, outlet water temperature, 주변 온도, 방전온도, coil temperature (NTC/PT1000)
고압 스위치, 저압 스위치 (평상시 닫혀 있음), water flow switch
- Hardware configuration for Phoenix Contact RFC 4001 (ready for direct use)

고압 스위치, 저압 스위치, oil pressure differential, water flow, 위상 순서, 비상 정지, local/remote switch, start command, stop command, defrost request
아날로그 입력 (일체 포함, 5–6 points): IB IL AI 4/I + IB IL PT4
Inlet water temperature, outlet water temperature, 주변 온도, 방전온도, evaporation/condensation temperature, high pressure sensor (선택 과목)

Compressor KM1, KM2 (별), KM3 (delta), condenser fan 1, condenser fan 2, 워터 펌프, 4-way valve, 알람 출력, defrost valve (선택 과목)
- Control logic (directly programmable in PLC)
- Start conditions
No alarms for high pressure / 저기압 / oil pressure differential / water flow / 위상 순서 / 비상 정지
Valid start command received
- Mode control
냉각: 4-way valve de-energized
난방: 4-way valve energized
오토매틱: auto-switching based on water temperature
- 순서 (standard heat pump)
Start → run water pump / fans first → time delay → star-delta start of compressor
Stop → stop compressor first → time delay to close valves / stop fans / stop water pump
- 보호 (immediate shutdown)
고압, 저기압, oil pressure differential, loss of water flow, 위상 순서 오류, 높은 방전 온도, anti-freeze protection, 센서 결함
- Defrost logic (heating mode)
Enter defrost based on timer + coil temperature conditions
Reverse 4-way valve, run compressor, stop fans, open defrost valve
Exit defrost when temperature setpoint or timer is reached
- Feasibility and risks
✅ Fully feasible
The RFC 4001 can implement all functions: 55kW star-delta control, I/O 수량, protection logic, mode switching

⚠️ Important notes
60헤르츠: Adjust program time delays and protection parameters for 60Hz operating conditions
T3 condition: Adapt high pressure protection setpoints and fan control logic for high-temperature environments
Original protocol: Cannot directly read data from the original PC4001; full disconnection and re-wiring of I/O is required
인증: CE/UL certifications for the unit will need re-evaluation after replacement (generally acceptable for industrial in-house use)
- Recommended solutions
- Keep the original PC4001
안정적인, no programming required, adjustable parameters via control panel
Disadvantage: no customizable logic, only monitoring via RS485
- Rewrite control with Phoenix Contact RFC 4001 (your intended solution)
장점: fully customizable logic, integration with upper computers / IoT, multi-unit linkage, advanced protection
구현: program according to the above I/O list, wiring and logic; fully capable of controlling this 55kW PASRW130S
- Short answer
예.
The Phoenix Contact RFC 4001 (PLC) can be fully programmed to control the Pentair PASRW130S-U-T3-60 (55kW) by programming the unit’s I/O points, star-delta sequence, operating modes and protection logic.
- Core conclusion (clear and definitive)
- The PC4001 installed on your unit
is a Pentair dedicated heat pump controller,
→ cannot be programmed with PLC software; only parameter adjustment via panel and RS485 communication is available.
- If your question is: Can the Phoenix Contact RFC 4001 (PLC) control this 55kW unit?
→ Absolutely yes, with full functionality.
You may remove the original control board and use the Phoenix Contact PC4001 PLC with custom programming to control this Pentair 55kW water chiller / heat pump unit.
Why is it possible? (Key matching points)
The Phoenix Contact RFC 4001 fully meets the control requirements of this PASRW130S 55kW unit:
Controls 55kW compressor star-delta starting ✅
Controls condenser fans, 워터 펌프, 4-way valve ✅
Reads high/low pressure switches, water flow, 위상 순서, emergency stop ✅
Reads NTC/PT1000 temperature probes (inlet/outlet/discharge/ambient) ✅
Implements cooling/heating/automatic/defrost logic ✅
Implements complete protection logic (고압, 저기압, oil pressure differential, 부동액, 초과 적재) ✅
Supports Modbus remote monitoring ✅
요컨대:
Sufficient hardware, sufficient I/O, programmable logic, compatible power rating.
Can the original PC4001 be programmed directly?
아니요.
The original PC4001 is a dedicated fixed-program controller, not a programmable PLC.
It cannot be programmed with software such as PC Worx or Codesys.
One-sentence summary
To use the Phoenix Contact RFC 4001 PLC with custom programming to control this Pentair 55kW unit:
