This \u003cstrong\u003enormally closed, fail-safe design\u003c\/strong\u003e means that in the event of a power failure or wiring fault, the valve defaults to closed, preventing uncontrolled heating circulation.\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#f0faf9;border:1px solid #c8e6e3;border-radius:6px;padding:13px;\"\u003e\n      \u003cdiv style=\"font-weight:700;color:#008377CF;margin-bottom:5px;\"\u003e✔ Potential-Free End Switch — Boiler \u0026amp; Pump Control\u003c\/div\u003e\n      \u003cdiv style=\"font-size:14px;\"\u003eThe \u003cstrong\u003epotential-free (volt-free) auxiliary end switch\u003c\/strong\u003e closes as the valve reaches its fully open position. This switch signal is used to fire the boiler and\/or start the circulating pump — ensuring the boiler only fires when at least one zone valve is fully open and water is circulating. This is the fundamental boiler interlock mechanism in S-plan and Y-plan wiring configurations. The end switch must be wired to the boiler's live connection (via the wiring centre) to achieve Part L-compliant boiler interlock.\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#f0faf9;border:1px solid #c8e6e3;border-radius:6px;padding:13px;\"\u003e\n      \u003cdiv style=\"font-weight:700;color:#008377CF;margin-bottom:5px;\"\u003e✔ Replaceable Powerhead — No Drain-Down\u003c\/div\u003e\n      \u003cdiv style=\"font-size:14px;\"\u003eThe \u003cstrong\u003emotor head (powerhead) can be removed and replaced without draining the heating system\u003c\/strong\u003e. The valve body remains in the pipework; the motorised head clips or screws on and off independently. If the motor fails — by far the most common V4043 failure — the entire valve does not need to be cut out of the pipework. The powerhead can be swapped in minutes with the system full and under pressure, making maintenance on a live system fast and cost-effective.\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#f0faf9;border:1px solid #c8e6e3;border-radius:6px;padding:13px;\"\u003e\n      \u003cdiv style=\"font-weight:700;color:#008377CF;margin-bottom:5px;\"\u003e✔ Manual Lever — Filling and Draining\u003c\/div\u003e\n      \u003cdiv style=\"font-size:14px;\"\u003eA \u003cstrong\u003emanual lever on the valve body\u003c\/strong\u003e allows the valve to be held open manually when filling or draining the heating system — without requiring electrical power to the actuator.

When the wiring centre calls for heat and sends power to the valve, the motor drives the valve open over approximately 12 seconds; when the call ends and power is removed, the return spring snaps the valve closed in about 5–6 seconds — no electrical power required to close. This \u003cstrong\u003enormally closed, fail-safe design\u003c\/strong\u003e means that in the event of a power failure or wiring fault, the valve defaults to closed, preventing uncontrolled heating circulation.\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#f0faf9;border:1px solid #c8e6e3;border-radius:6px;padding:13px;\"\u003e\n      \u003cdiv style=\"font-weight:700;color:#008377CF;margin-bottom:5px;\"\u003e✔ Potential-Free End Switch — Boiler \u0026amp; Pump Control\u003c\/div\u003e\n      \u003cdiv style=\"font-size:14px;\"\u003eThe \u003cstrong\u003epotential-free (volt-free) auxiliary end switch\u003c\/strong\u003e closes as the valve reaches its fully open position. This switch signal is used to fire the boiler and\/or start the circulating pump — ensuring the boiler only fires when at least one zone valve is fully open and water is circulating. This is the fundamental boiler interlock mechanism in S-plan and Y-plan wiring configurations. The end switch must be wired to the boiler's live connection (via the wiring centre) to achieve Part L-compliant boiler interlock.

\u003cstrong\u003etwin pack of two Honeywell Home V4043H1056\/U 22mm motorised zone valves\u003c\/strong\u003e — the most commonly specified zone valve bundle for a complete S-plan central heating installation. In a standard S-plan configuration, \u003cstrong\u003eone valve is installed on the heating circuit and one on the hot water circuit\u003c\/strong\u003e, providing independent motorised control of each zone with individual end switches that fire the boiler and pump only when needed. Buying as a twin pack ensures a matched pair with identical specifications and wiring — eliminating any uncertainty about compatibility between a new valve and an existing one. Each valve features motor-open\/spring-return action, a normally closed fail-safe position, a potential-free SPST end switch, replaceable powerhead, manual lever, and 1 metre heat-resistant flying lead.\n  \u003c\/p\u003e\n  \u003cdiv style=\"border-left:4px solid #008377CF;background:#e6f4f3;padding:10px 16px;margin-bottom:22px;border-radius:0 6px 6px 0;\"\u003e\n    \u003cstrong style=\"color:#005c54;\"\u003eℹ Why Two Valves? — S-Plan Explained\u003c\/strong\u003e\u003cbr\u003e\n    In an \u003cstrong\u003eS-plan\u003c\/strong\u003e (or S-plan Plus) central heating system — by far the most common UK configuration — two separate two-port zone valves independently control the flow of water to the heating circuit (radiators or UFH) and the hot water circuit (cylinder coil). When a thermostat calls for heat, it signals the appropriate zone valve to open; as the valve reaches full open, its end switch fires the boiler and starts the pump. When demand is met, the valve closes, the end switch opens, and the boiler shuts down. This provides \u003cstrong\u003eindependent time and temperature control of heating and hot water\u003c\/strong\u003e, satisfying Part L of the Building Regulations boiler interlock requirements. Two V4043H1056 valves and a suitable wiring centre are the core of this system.\n  \u003c\/div\u003e\n  \u003cdiv style=\"border-left:4px solid #f59e0b;background:#fff8e1;padding:10px 16px;margin-bottom:22px;border-radius:0 6px 6px 0;\"\u003e\n    \u003cstrong style=\"color:#b45309;\"\u003e⚡ Y-Plan Note\u003c\/strong\u003e — If your system uses a \u003cstrong\u003eY-plan configuration\u003c\/strong\u003e (single mid-position valve), you require one \u003cstrong\u003ethree-port mid-position valve\u003c\/strong\u003e (such as the Honeywell V4073A) rather than two two-port valves.

When the wiring centre calls for heat and sends power to the valve, the motor drives the valve open over approximately 12 seconds; when the call ends and power is removed, the return spring snaps the valve closed in about 5–6 seconds — no electrical power required to close. This \u003cstrong\u003enormally closed, fail-safe design\u003c\/strong\u003e means that in the event of a power failure or wiring fault, the valve defaults to closed, preventing uncontrolled heating circulation.\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#f0faf9;border:1px solid #c8e6e3;border-radius:6px;padding:13px;\"\u003e\n      \u003cdiv style=\"font-weight:700;color:#008377CF;margin-bottom:5px;\"\u003e✔ Potential-Free End Switch — Boiler \u0026amp; Pump Control\u003c\/div\u003e\n      \u003cdiv style=\"font-size:14px;\"\u003eThe \u003cstrong\u003epotential-free (volt-free) auxiliary end switch\u003c\/strong\u003e closes as the valve reaches its fully open position. This switch signal is used to fire the boiler and\/or start the circulating pump — ensuring the boiler only fires when at least one zone valve is fully open and water is circulating. This is the fundamental boiler interlock mechanism in S-plan and Y-plan wiring configurations. The end switch must be wired to the boiler's live connection (via the wiring centre) to achieve Part L-compliant boiler interlock.\u003c\/div\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"background:#f0faf9;border:1px solid #c8e6e3;border-radius:6px;padding:13px;\"\u003e\n      \u003cdiv style=\"font-weight:700;color:#008377CF;margin-bottom:5px;\"\u003e✔ Replaceable Powerhead — No Drain-Down\u003c\/div\u003e\n      \u003cdiv style=\"font-size:14px;\"\u003eThe \u003cstrong\u003emotor head (powerhead) can be removed and replaced without draining the heating system\u003c\/strong\u003e.

However, many properties use the immersion heater purely as a backup — if the cylinder is already zone-valve-controlled via the ATF500DHW, the immersion can be left on its standard thermostat as a safety fallback without requiring additional evohome integration.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails style=\"border-bottom:1px solid #c8e6e3;\"\u003e\n      \u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#f0faf9;\"\u003eWhat is the difference between S-plan and Y-plan, and does this kit work with both?\u003c\/summary\u003e\n      \u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003eYes — the ATF500DHW works with both. \u003cstrong\u003eS-plan\u003c\/strong\u003e systems use separate 2-port motorised zone valves for the heating circuit and the hot water circuit — the BDR91 in this kit switches the hot water zone valve. \u003cstrong\u003eY-plan\u003c\/strong\u003e systems use a single 3-port mid-position diverter valve that routes flow to heating only, hot water only, or both simultaneously — the BDR91 provides the hot water demand signal to the diverter valve's mid-position terminal.

The evohome system and BDR91 become the new hot water controller.

Because the powerhead is designed to be replaced without draining the system, this part allows a faulty zone valve to be returned to full operation in minutes — no isolating the boiler, no drain-down, no cutting out pipework, no compression fittings to remake. The replacement head includes the end switch, spring return mechanism, and a \u003cstrong\u003e1 metre heat-resistant pre-wired cable\u003c\/strong\u003e, and attaches to the existing valve body with two screws and two locating pegs.\n  \u003c\/p\u003e\n\n  \u003c!-- ── RED SAFETY CALLOUT ─────────────────────────────────────── --\u003e\n  \u003cdiv style=\"border-left:4px solid #c0392b;background:#fff5f5;padding:10px 16px;margin-bottom:14px;border-radius:0 6px 6px 0;\"\u003e\n    \u003cstrong style=\"color:#c0392b;\"\u003e⚠ Always isolate the mains supply before removing or refitting the actuator assembly.\u003c\/strong\u003e The powerhead must be replaced by a qualified person.

However, before replacing, it is worth checking: (1) the manual lever — if it has been left in MAN. OPEN, the valve won't respond to electrical signals; (2) the wiring connections — a loose or corroded terminal can cause erratic behaviour; (3) the valve body itself — in rare cases the spindle can seize in the body rather than the motor failing. To test the body independently, move the manual lever to MAN. OPEN and check if water flows through the correct port. If the body appears free and the wiring is sound, the powerhead is almost certainly the fault. Replacing the powerhead first is the correct diagnostic step before considering full valve replacement.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails style=\"border-bottom:1px solid #c8e6e3;\"\u003e\n      \u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#f0faf9;\"\u003eAfter fitting, my central heating and hot water both come on together — what's wrong?\u003c\/summary\u003e\n      \u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003eThis is the most common post-installation symptom and is almost always a \u003cstrong\u003ewiring error\u003c\/strong\u003e, not a faulty head. The five wires from the valve connect to: neutral (blue), live (brown), hot water demand (orange — drives motor to mid-position), central heating demand (white — drives motor fully open), and auxiliary output (grey — fires the boiler\/pump). If orange and white are swapped, both zones will fire simultaneously. Cross-reference your wiring against the Honeywell installation guide 95C-10656, paying particular attention to the auxiliary switch output on grey — this wire must only be connected once the valve reaches its end position. If replacing a 6-wire valve with an internal relay, specific additional wiring changes are required — the brown wire from the old relay is omitted and the cylinder thermostat C and 1 terminals must be reversed.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails style=\"border-bottom:1px solid #c8e6e3;\"\u003e\n      \u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#fff;\"\u003eDo I need to isolate the boiler before replacing the head?\u003c\/summary\u003e\n      \u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003eYes — \u003cstrong\u003eall electrical power to the heating system must be isolated\u003c\/strong\u003e before starting work. This means switching off at the programmer\/time control, at the system's unswitched fused spur, or at the consumer unit's heating circuit. The valve operates at 230V and is connected to the wiring centre alongside the boiler, pump, and thermostats — live conductors are present in the junction box and at the valve terminals even when the heating is not actively calling. A shock from incorrectly isolated wiring at a junction box is a serious risk. Isolation must be confirmed with a voltage tester before any electrical connections are disturbed.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#f0faf9;\"\u003eCan this head convert a 3-port diverter valve to a mid-position valve?\u003c\/summary\u003e\n      \u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003eYes — in principle. A 3-port diverter (V4043 body) and a 3-port mid-position valve (V4073A body) use a similar physical construction, and the 40003916-003 powerhead can be fitted to a V4043 body, converting it electrically from a diverter to a mid-position configuration. The full Y-plan wiring (5-wire: neutral, live, orange HW, white CH, grey auxiliary) must then be connected correctly. However, \u003cstrong\u003ebefore doing this, confirm the V4043 body valve seats are compatible with mid-position operation\u003c\/strong\u003e — a diverter valve is designed to fully route flow to one port or the other, while a mid-position valve is designed to allow partial flow through both ports simultaneously. If the body seating is not designed for this, mid-position flow balance may not be correct. Consult the Honeywell installation guide and a qualified heating engineer before proceeding.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":64292701602141,"sku":"40003916-003\/U","price":107.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/2051\/3629\/files\/head-40003916-003-honeywell.webp?v=1776842078"},{"product_id":"drayton-22mm-motorised-2-port-zone-valve-snap-on-actuator-5-wire-spst-switch-pack-of-2-p27100","title":"Drayton 22mm Motorised 2 Port Zone Valve \u0026 Snap-On Actuator (5 Wire SPST Switch) - Pack of 2 P27100","description":"\u003c!-- SEO Product Name: Drayton 22mm Motorised 2 Port Zone Valve \u0026 Snap-On Actuator (5 Wire SPST Switch) - Pack of 2 P27100 --\u003e\n\u003cdiv style=\"font-size:16px; max-width:900px; margin:0 auto; color:#2B2B2B; line-height:1.6; font-family:Arial, Helvetica, sans-serif;\"\u003e\n\u003cp style=\"font-size:16px; line-height:1.7; color:#2B2B2B; margin:0 0 16px 0;\"\u003eThe \u003cstrong\u003eDrayton 22mm Motorised 2 Port Zone Valve \u0026amp; Snap-On Actuator (MPN: 27100)\u003c\/strong\u003e, also known by its full model reference \u003cstrong\u003eZA5\/679-2\u003c\/strong\u003e, is the industry-standard zone valve for controlling individual heating or hot water circuits in domestic wet central heating systems.
