product details
Product Overview
W713/W713B is an intelligent controller series for water supply and drainage systems. It supports one pump with one variable frequency controller and can coordinate up to six pumps in a linkage system.
The series is suitable for constant pressure, constant differential pressure, constant temperature and constant differential temperature water supply applications.
Key Selling Points
- Multi-pump control supports up to six pumps in linkage water supply.
- Sleep function stops operation when there is no water consumption to save energy.
- Freeze-proofing and anti-clogging functions help protect the pump and pipe system.
- Power-on restart and master fault shift support continued operation after abnormal conditions.
- Control modes include constant pressure, constant differential pressure, constant temperature, constant differential temperature and manual mode.
- Linkage modes include synchronous, master-slave, big-small pump combination, one duty one standby and one VFD drive two pumps.
- Terminal control supports electronic contact gauge control, manual/auto control, run/stop control and automatic water level control.

Interface and Control
- Main circuit terminals provide input power, motor output and grounding connections according to the W713 or W713B structure.
- Control terminals support pressure feedback, water level control, manual/auto switching and system linkage signals.
- Relay and alarm functions support water supply fault handling.
- The system can connect with the company’s HMI touch screen for expanded operation.
Application Scenarios
- Constant pressure water supply.
- Constant differential pressure water supply.
- Constant temperature water supply.
- Constant differential temperature water supply.
- Multi-pump water supply systems with automatic alternation and standby operation.
Installation and Use Notes
- If used as a master controller, connect the required transducer before operation.
- For slave use without AI1 feedback, set the sensor open-circuit detection value according to the manual to clear feedback loss alarm.
- Install on fireproof material and wait until the power indicator is off before opening the cover.
- Avoid direct sunlight, rain, frost, snow, violent vibration and corrosive environments.
FAQs
What is W713B used for? ▶
W713B is a water-pump controller for systems where pumps work together. It can use pressure or temperature readings when the system includes the required sensors and has been set up for that use.
Can W713B run two pumps from one inverter? ▶
Yes, but only in the specific W713B one-inverter, two-pump mode. This setup requires a matching control cabinet and must be designed for the pumps being used.
How many pumps can a W713B system manage? ▶
The W713/W713B manual describes systems of up to six pumps. In standard linked-pump arrangements, each pump has its own controller; the special two-pump mode follows separate requirements.
What parts are normally considered in a pressure system? ▶
The system documentation includes a pressure tank, check valve, and pressure sensor. The final parts needed depend on the pump layout and the pipework at the site.
Can W713B maintain pressure automatically? ▶
It supports pressure-based control with a suitable pressure sensor and correct settings. Steady pressure also depends on correct pump size, pipework, and sensor installation.
Can W713B make pumps take turns? ▶
The W713/W713B manual includes automatic alternation for linked pumps. Choose the pump arrangement and rotation settings when the full system is set up.
Can W713B be used with a temperature sensor? ▶
The combined series manual describes temperature-related control for suitable uses. Use it only when the selected model, temperature sensor, and system design are confirmed for that job.
What should I do if pressure is low or unstable? ▶
Do not change settings at random. Check the pressure sensor, water inlet, pump direction, pipework, check valve, and pressure tank against the system plan.
