Hi I would like to upgrade my Main Combi 24 HE (which uses the Grasslin mechanical timer) to a wifi enabled boiler. Will this unit fit and also can this be paired with a wireless room stat? Many thanks.
It will fit your boiler. It will not pair to a wireless room stat. If you need a wireless room stat, you will need HCO code BU781.
Hi I'm looking to run my baxi duo tec 33 combi boiler via WiFi with an ap to programme the sequence of on off.. Is this possible, and if so how do I go about it please
Assuming you have the mechanical timer on the front of the boiler, you just swap it for this. The procedure will be explained in your boiler manual under changing the timer.
How do I connect it to my wifi router? Had to replace router and now can't access settings it via phone app....
Long press the button to reset it back to factory settings. Then re-add it in the app as a new device.
Will this fit the Baxi combi 105e and if so does this work from an app on your phone
Yes it will. Yes, you control it with an app.
I have a grasslin QE7 running 1 immersion element in a water tank. Will this replace the grasslin unit and clip into the harness?
It will replace it, but you will need to change the backplate.
