Van Remmen 312440 Control unit 80W for V150

The Van Remmen 312440 is the genuine 80W control unit specified for the V150 UV disinfection system, providing the power supply and switching the lamp needs to reach and maintain full UV output. WrekinWater supplies this as a like-for-like replacement when the original control unit on a V150 fails. It's an electrical part only — the lamp and quartz sleeve are separate consumables.

Signs this needs replacing

• The V150 doesn't power up at all when switched on.
• The lamp stays dark even after fitting a lamp you know is good.
• No display, no indicator lights, and no response from the unit.
• A fuse in the unit or supply blows as soon as it's switched on.

The control unit supplies and regulates the current the 80W lamp needs to strike and run at full output inside the V150 reactor. If it degrades or fails, the lamp may run weak, flicker, or not light at all, which means the water passing through isn't being reliably disinfected even though the system appears to be running. As the part carrying the mains connections, a faulty unit should be treated as an electrical safety issue too.

WrekinWater is a family-run business based in Bettisfield, Shropshire, with more than 50,000 customers served over 15 years and an "Excellent" Trustpilot rating. We stock genuine Van Remmen parts so your V150 gets the correct control unit rather than a mismatched substitute.

How to replace it

1. Switch off and unplug the V150 control unit from the mains before starting any work.
2. Note how the lamp lead and any sensor or alarm wiring connects to the existing unit.
3. Disconnect the leads and remove the old 312440 unit from its mounting position.
4. Fit the new unit in the same place and reconnect each lead exactly as noted.
5. Restore the power supply and check the lamp strikes and any indicators operate normally.
6. If the connections don't match a simple plug-in swap, or you're not confident working with mains wiring, ask a qualified electrician or water treatment engineer to fit it.
