Может ли Pentair PASRW130S-U-T3-60 (55кВт) программироваться с помощью PC4001?

PHNIX PC4001 — главный контроллер. / плата управления, предназначенная для оборудования, включая тепловые насосы типа «воздух-вода»

Заключение: Да, but there are two approaches — directly replace the original control board, or use the PC4001 (ПЛК) 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 специальный контроллер теплового насоса PC4001 (not the Phoenix Contact RFC 4001 ПЛК). Your question is: Can the Phoenix Contact RFC 4001 (ПЛК) be programmed to control this 55kW unit?

1. Первый, distinguish between the two “PC4001” единицы (критический)

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: охлаждение / обогрев / defrosting / 4-ходовой клапан / вентилятор / водяной насос / protection logic

Интерфейсы: temperature probes (NTC/PT1000), high/low pressure switches, water flow switch, компрессор, вентилятор, 4-ходовой клапан, водяной насос, выход тревоги

Cannot be programmed with PLC software; parameters can only be set via the control panel or RS485 communication

Phoenix Contact RFC 4001 (ПЛК)

General-purpose PLC, requires matching I/O modules

Can fully replace the original PC4001 and control this 55kW unit with custom programming

2. Key control requirements for the Pentair PASRW130S-U-T3-60 (55кВт)

Компрессор: 55кВт, 380V/60Hz, запуск звезда-треугольник (KM1/KM2/KM3)

Operating modes: охлаждение / обогрев / automatic / defrosting

Controlled devices:

Компрессор (звезда-треугольник)

Condenser fans (1–2 units)

Evaporator / водяной насос

4-ходовой клапан (cooling/heating switching)

Water flow switch, high/low pressure protection, oil pressure differential, discharge temperature, anti-freeze protection

Датчики:

Inlet water temperature, outlet water temperature, температура окружающей среды, discharge temperature, coil temperature (NTC/PT1000)

High pressure switch, low pressure switch (нормально закрытый), water flow switch

3. Hardware configuration for Phoenix Contact RFC 4001 (ready for direct use)

Контроллер: RFC 4001 (PC4001)

Цифровые входы (ОТ, 10 очки): IB IL 24 ОТ 16

High pressure switch, low pressure switch, oil pressure differential, water flow, последовательность фаз, аварийная остановка, local/remote switch, start command, stop command, defrost request

Аналоговые входы (ИИ, 5–6 points): IB IL AI 4/I + IB IL PT4

Inlet water temperature, outlet water temperature, температура окружающей среды, discharge temperature, evaporation/condensation temperature, high pressure sensor (необязательный)

Релейные цифровые выходы (ДЕЛАТЬ, 8–10 points): IB IL 24 DO 16-R

Compressor KM1, KM2 (звезда), KM3 (дельта), вентилятор конденсатора 1, вентилятор конденсатора 2, водяной насос, 4-ходовой клапан, выход тревоги, defrost valve (необязательный)

4. Логика управления (directly programmable in PLC)
5. Start conditions

No alarms for high pressure / low pressure / oil pressure differential / water flow / последовательность фаз / аварийная остановка

Valid start command received

2. Mode control

Охлаждение: 4-way valve de-energized

Обогрев: 4-way valve energized

Автоматический: auto-switching based on water temperature

3. Последовательность (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

4. Защита (immediate shutdown)

High pressure, low pressure, oil pressure differential, loss of water flow, phase sequence error, high discharge temperature, anti-freeze protection, sensor fault

5. 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

5. Feasibility and risks

✅ Fully feasible

The RFC 4001 can implement all functions: 55kW star-delta control, Количество ввода-вывода, protection logic, переключение режима

Лестничная диаграмма (ЛД) / Функциональная блок-схема (ФБД) programming in PC Worx, consistent with standard water chiller/heat pump program structure

⚠️ Important notes

60Гц: 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

Сертификаты: CE/UL certifications for the unit will need re-evaluation after replacement (generally acceptable for industrial in-house use)

6. Recommended solutions
7. Keep the original PC4001

Стабильный, no programming required, adjustable parameters via control panel

Недостаток: no customizable logic, only monitoring via RS485

2. Rewrite control with Phoenix Contact RFC 4001 (your intended solution)

Преимущества: fully customizable logic, integration with upper computers / Интернет вещей, multi-unit linkage, advanced protection

Выполнение: program according to the above I/O list, wiring and logic; fully capable of controlling this 55kW PASRW130S

7. Short answer

Да.

The Phoenix Contact RFC 4001 (ПЛК) can be fully programmed to control the Pentair PASRW130S-U-T3-60 (55кВт) by programming the unit’s I/O points, star-delta sequence, operating modes and protection logic.

1. Основной вывод (clear and definitive)
2. 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.

2. If your question is: Can the Phoenix Contact RFC 4001 (ПЛК) 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)
