Vaillant Boiler Over Run control

[Leslie1407]

Hello,

I've just had a regular Ideal boiler (15 yrs ols) removed and replaced with a Vialliant 430 boiler with Nest control. My Boiler is located in my garage but the Nest is in the emersion cupboard. The pump is located in the emersion cupboard. The boiler requires a separate feed from the control board back to the Pump and is referred to as the Over run feed. This keeps the pump going for a few minutes after boiler call for heat is stopped. Now here is the issue, I don't want to pull up all the floors to lay a new feed for just the overrun so I'm thinking if I use the signal at the boiler (240v) to power a remote WiFi or RF transmitter to signal over run and then place the receiver in the emersion cupboard that picks up the trigger and sends 240v feed to the pump and when over run turns off the signal is stopped and the pump feed is removed. Simply really but can I find such a unit to do this, nope so can anybody suggest such a device otherwise I'm going to have to make my own.

Is overrun still required on these boilers? Haven't wired up a conventional boiler in a while but I can't seem to find anything in the manual stating it is required, but then I can't see anything saying it isn't either.

Are you Gas safe registered? You stated that you have had the boiler fitted but then state that you do not want to lift boards?

Vaillant say that they do not need one but then they released a suppressor because they realised they did need one. I would steal a wire from the old timer cable if you have gone RF

See my post above. No need to take floors up.

Hi, nope engineer fitted the boiler and its working fine without the over run but for it to be covered under warranty it should have the over run wired in. When I say I don't want to cut up the flooring because they not floor boards but the chipboard stuff and its likely to cause a mess. I've already had somebody reply with the info I needed regards the remote kit so all good.

Your missing my point. Your going to spend £99.00 on an RF box when you could just use a cable from the old timer as that cable will go to the 10 way in the airing cupboard and the boiler. The old wiring is now redundant as the rf receiver is now in the airing cupboard?
