1. தயாரிப்பு முடிந்துவிட்டதுview
The Drayton ZA5 replacement actuator is designed for compatibility with the Drayton 22mm 2-port motorised valve, specifically part number 27100. This actuator is a critical component in central heating systems, responsible for controlling the flow of water to a specific heating zone by opening and closing the associated valve.

5. நிறுவல் வழிகாட்டி
This section provides general guidance for replacing a Drayton ZA5 actuator. Always refer to the specific wiring diagrams provided with your heating system and consult a qualified professional if unsure.

- வயர் ஸ்ட்ரிப்பர்ஸ்/கட்டர்ஸ்
- தொகுதிtagஇ சோதனையாளர்
நிறுவல் படிகள்:
- பவர் ஆஃப்: Locate the main electrical supply to your central heating system and switch it off at the consumer unit/fuse box. Verify that power is off using a voltagஇ சோதனையாளர்.
- Access Actuator: Identify the existing actuator on your 2-port motorised valve. It is typically secured by screws or clips.
- வயரிங் துண்டிக்கவும்: Carefully note or photograph the existing wiring connections. Disconnect the five wires from the terminal block.
- Remove Old Actuator: Unscrew or unclip the old actuator from the valve body. The valve body itself usually remains in place.
- Install New Actuator: Position the new Drayton ZA5 actuator onto the valve body, ensuring it aligns correctly. Secure it with the provided screws or clips.
- வயரிங் இணைக்க: Connect the five wires of the new actuator to the terminal block, matching the connections noted in step 3. The typical wire colors and functions are:
- Brown: Live (Switched Live from programmer/thermostat)
- நீலம்: நடுநிலை
- பச்சை/மஞ்சள்: பூமி
- Orange: Switched Live (to boiler/pump)
- Grey: Return (from valve microswitch)
- பாதுகாப்பான உறை: Ensure all wires are neatly tucked away and secure the actuator cover.
- சக்தியை மீட்டமை: Switch the main electrical supply back on.
- சோதனை அமைப்பு: Test the heating system to ensure the actuator operates correctly, opening and closing the zone valve as commanded by the thermostat or programmer.
6. இயக்க வழிமுறைகள்
The Drayton ZA5 actuator operates automatically as part of your central heating system. It does not require manual intervention for its primary function.
- When the thermostat calls for heat in the zone controlled by the valve, the actuator receives an electrical signal, causing it to open the valve.
- Once the thermostat's set temperature is reached, or the heating program ends, the electrical signal is removed, and the actuator closes the valve, typically via a spring return mechanism.
- A small lever or button may be present on the actuator for manual override or to check valve operation during installation. Refer to your heating system's overall manual for specific instructions on using this feature, if available.
7. பராமரிப்பு
The Drayton ZA5 actuator is designed to be maintenance-free under normal operating conditions. No user-serviceable parts are inside the unit.
- Keep the exterior of the actuator clean and free from dust and debris. Use a dry cloth for cleaning.
- Do not attempt to lubricate any internal components.
- Periodically check the wiring connections for any signs of wear or looseness. Ensure power is off before inspecting connections.
- If the actuator shows signs of damage or malfunction, it should be replaced by a qualified professional.
8. சரிசெய்தல்
If you experience issues with your heating system that you suspect are related to the zone valve actuator, consider the following common problems and solutions:
| பிரச்சனை | சாத்தியமான காரணம் | தீர்வு |
|---|---|---|
| No heat in zone | Actuator not opening valve; no power to actuator; faulty thermostat/programmer. | Check thermostat setting. Verify power to actuator (with power off, check wiring). Replace actuator if it does not respond to power. |
| Zone always hot (heating won't turn off) | Actuator stuck open; faulty microswitch in actuator; wiring fault. | Check if actuator returns to closed position when power is off. If not, replace actuator. Check wiring for shorts. |
| Actuator makes buzzing noise but doesn't move | Motor fault; obstruction in valve. | Replace actuator. Check valve for mechanical obstruction (requires draining system). |
| Actuator feels hot to touch | Normal operation (slight warmth); internal fault (excessive heat). | Slight warmth is normal. If excessively hot, disconnect power and replace actuator. |
For persistent issues, it is recommended to contact a qualified heating engineer.
