PHNIX PC4001 เป็นตัวควบคุมหลัก / แผงควบคุมที่ออกแบบมาสำหรับอุปกรณ์ต่างๆ รวมถึงปั๊มความร้อนจากอากาศสู่น้ำ
บทสรุป: ใช่, but there are two approaches — directly replace the original control board, or use the PC4001 (บมจ) 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 บมจ). Your question is: Can the Phoenix Contact RFC 4001 (บมจ) be programmed to control this 55kW unit?
- อันดับแรก, distinguish between the two “พีซี4001” หน่วย (critical)
Original PC4001 (dedicated heat pump board)
The factory-installed controller for your unit: dedicated temperature control board for swimming pools and heat pumps
Built-in functions: cooling / เครื่องทำความร้อน / defrosting / 4-way valve / พัดลม / ปั๊มน้ำ / protection logic
Interfaces: temperature probes (NTC/PT1000), high/low pressure switches, water flow switch, คอมเพรสเซอร์, พัดลม, 4-way valve, ปั๊มน้ำ, เอาต์พุตแจ้งเตือน
Cannot be programmed with PLC software; parameters can only be set via the control panel or RS485 communication
Phoenix Contact RFC 4001 (บมจ)
General-purpose PLC, requires matching I/O modules
Can fully replace the original PC4001 and control this 55kW unit with custom programming

- Control logic (directly programmable in PLC)
- Start conditions
No alarms for high pressure / ความดันต่ำ / oil pressure differential / water flow / ลำดับเฟส / emergency stop
Valid start command received
- Mode control
ระบายความร้อน: 4-way valve de-energized
เครื่องทำความร้อน: 4-way valve energized
Automatic: auto-switching based on water temperature
- Sequence (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
- การป้องกัน (immediate shutdown)
แรงดันสูง, ความดันต่ำ, oil pressure differential, loss of water flow, ข้อผิดพลาดลำดับเฟส, อุณหภูมิจำหน่ายสูง, anti-freeze protection, ความผิดปกติของเซ็นเซอร์

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 quantity, protection logic, การสลับโหมด
Ladder Diagram (LD) / Function Block Diagram (FBD) programming in PC Worx, consistent with standard water chiller/heat pump program structure
⚠️ Important notes
60เฮิรตซ์: 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
การรับรอง: 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
Stable, 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)
ข้อดี: fully customizable logic, integration with upper computers / IoT, multi-unit linkage, advanced protection
Implementation: program according to the above I/O list, wiring and logic; fully capable of controlling this 55kW PASRW130S

ใช่.
The Phoenix Contact RFC 4001 (บมจ) can be fully programmed to control the Pentair PASRW130S-U-T3-60 (55กิโลวัตต์) 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.
