Boiler switching via wifi signal

[Bogart]

Mainslink are fine - very good for remote boiler / UFH control. The problems ( that I have encountered) are when people overload them. I have never had (installed) one that has failed.

How would one overload a unit such as this?

It's just an insurance policy, not specific to any particular unit. I've found that when wireless systems stop working diagnosing faults, particularly intermittent ones, is difficult unless you do it by substitution. The supplier recommended by SJB060685 currently has a 4-week delivery time. That's longer than I'd want to be without a working heating system.

Four weeks from the manufacturer.
I have mine on next day delivery from a supplier and cheaper
I intend to leave the T&E in situ i

They are rated at just over 4amps - the connection block sizing is a good clue - but I have seen them connected to switch 10amps plus!

If you do decide to go for one of these and your boiler has pump over run then you'll need the "Mainslink Pro" as it sends and receives both ways. Normal mainslink will only transmit one way

if you are looking for pump overrun capability Mains Switch RF is half the price of Mains Link and was the trigger for Mains Link to introduce the pro option - sadly they got the pricing wrong!

I might be mistaken but how does this unit fit my needs? I need 2 seperate, ie MainslinkPro, signals. One to swich boiler on and off and another for the pump overun.

You need mains switch rf mate

Mains Switch RF will deliver pump overrun. It scans for a signal, then initially powers through a super capacitor ( if that is the correct terminology).

More often used for HVAC rather than domestic, but will still do the job.

There are other systems around, that can do the same job that also take a single RF channel, but then split into a bank of timed relays - in essence to give sequential multichannel capability.

Where is the pump located? Where does it get its supply from? (If the boiler has pump overrun, the pump is normaly supplied from the boiler.)

If it's an external pump then that's probably not the case

Pump is in airing cupboard next to control panel. Boiler is in outhouse some 20m away. Boiler has pump over run capability but not used as a few years ago, before I moved in, it replaced a really old boiler without overun and nobody gave it a thought.
