1. Introduction
This manual provides essential information for the installation, operation, and maintenance of your Honeywell Electric 2-way/3-way Fan Coil Water Valve. The valve is designed for controlling water flow in fan coil units, air conditioning systems, and garden irrigation applications. It consists of two main parts: the driver (actuator) and the valve body.
The valve body is cast from high-quality brass, ensuring durability and reliable performance. The driver is constructed from engineering plastic and includes a built-in limit point switch for precise control and convenient system debugging. This series of electric valves can be integrated with various temperature control switches to achieve energy-saving operation.

4. Setup and Installation
4.1 Mechanical Installation
- Ensure the power supply is disconnected before beginning installation.
- Identify the correct port size (DN15, DN20, DN25, or DN32) and thread type (NPT for I Type Two way, BSP for T Type Three way) for your system.
- Apply appropriate thread sealant to the pipe threads.
- Carefully screw the valve body into the piping system, ensuring a tight, leak-free connection. Do not overtighten.
- Ensure the valve is installed in an accessible location for future maintenance.
- For 3-way valves, ensure the flow direction arrows on the valve body align with your system's flow.
4.2 Electrical Wiring
WARNING: All electrical work should be performed by a qualified electrician and comply with local electrical codes. Ensure the power supply is OFF before wiring.
The valve operates on 220VAC. The actuator supports both two-wire (S.P.S.T. Controller) and three-wire (S.P.D.T. Controller) configurations.
4.2.1 3-Wire Configuration (S.P.D.T. Controller)
This configuration uses a Single Pole Double Throw (S.P.D.T.) controller. The wires are typically Brown, Black, and Blue.
- Connect the Brown wire to the 'Close' terminal (SW1) of the valve actuator and to the Normally Closed (NC) contact of the S.P.D.T. controller.
- Connect the Black wire to the 'Open' terminal (SW2) of the valve actuator and to the Normally Open (NO) contact of the S.P.D.T. controller.
- Connect the Blue wire to the Neutral (N) line of the power supply.
- Connect the Live (L) line of the power supply to the common terminal of the S.P.D.T. controller.
- Ensure all connections are secure and insulated.
4.2.2 2-Wire Configuration (S.P.S.T. Controller)
This configuration uses a Single Pole Single Throw (S.P.S.T.) controller. The wires are typically Brown, Black, and Blue, but the control logic differs.
- Connect the Brown wire to the 'Close' terminal (SW1) of the valve actuator.
- Connect the Black wire to the 'Open' terminal (SW2) of the valve actuator.
- Connect the Blue wire to the Neutral (N) line of the power supply.
- The S.P.S.T. controller typically switches the Live (L) line to either the Brown or Black wire to control valve position. Refer to your specific S.P.S.T. controller's instructions for exact connections.
- Ensure all connections are secure and insulated.
5. Operating Instructions
The electric valve operates by receiving an electrical signal from a connected controller (e.g., a thermostat or a timer). When a signal is received, the actuator moves the valve to either an open or closed position, or to divert flow in a 3-way configuration.
- Power On: Once installed and wired correctly, apply power to the system. The valve will typically move to its default (Normally Closed) position or the position dictated by the controller.
- Control via Thermostat/Controller: The valve's operation is managed by an external temperature control switch or other automation system. When the controller calls for heating/cooling (or water flow), it sends a signal to the valve actuator.
- Valve Movement: The actuator will take approximately 16 seconds to fully open or close the valve. During this time, the 5VA power consumption occurs.
- Monitoring: Observe the system to ensure the valve is opening and closing as expected in response to the controller's commands.
6. Maintenance
The Honeywell Electric Water Valve is designed for reliable, long-term operation with minimal maintenance. However, periodic checks can help ensure optimal performance.
- Visual Inspection: Regularly inspect the valve and actuator for any signs of leaks, corrosion, or physical damage.
- Wiring Check: Ensure all electrical connections remain secure and free from damage or corrosion.
- Operation Check: Periodically verify that the valve opens and closes smoothly and completely in response to control signals.
- System Pressure: Ensure the system pressure remains within the allowable limits (Valve body pressure: 1.6MPa, Allowable pressure difference: 1.0MPa).
- Cleaning: Keep the exterior of the actuator clean and free from dust or debris. Do not use harsh chemicals.
7. Troubleshooting
If you encounter issues with your electric water valve, refer to the following common troubleshooting steps:
- Valve Not Operating:
- Check if the power supply (220VAC) is connected and active.
- Verify all wiring connections are correct and secure according to the diagrams in Section 4.2.
- Ensure the external controller (thermostat, timer) is functioning correctly and sending the appropriate signals.
- Check for any obstructions in the valve's path or actuator mechanism.
- Leaking Valve:
- Turn off the water supply immediately.
- Inspect pipe connections for proper sealing and tightness. Re-apply thread sealant if necessary.
- Check the valve body for cracks or damage. If damaged, the valve may need replacement.
- Valve Not Fully Opening/Closing:
- Check for sufficient system pressure.
- Ensure the actuator is securely mounted to the valve body.
- Verify the control signal from the external device is consistent and sustained for the full 16-second operation cycle.
If problems persist after following these steps, contact qualified personnel for assistance.
8. User Tips
- System Compatibility: Always ensure the valve's specifications (voltage, port size, temperature, pressure) match your existing system requirements before purchase and installation.
- Professional Installation: For complex HVAC or plumbing systems, consider professional installation to ensure correct wiring and optimal performance.
- Regular Monitoring: Periodically check the valve's operation, especially after seasonal changes or system adjustments, to confirm it's functioning as intended.
- Energy Saving: Utilize the valve with a programmable thermostat to optimize water flow based on occupancy or time schedules, maximizing energy savings.
