Q: 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.
A: 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.

Q: 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
A: 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.

Installed this to control a 3KW immersion heater a year ago in a Baxi tank. Connected quite easily to a 2.4Ghz network via the "Smart Life" App on Android - I've no reason to think that IOS would be any different. It is fully controllable via Google Home - voice control or via the App. The only grief I had with it was remembering how to switch Networks when I changed broadband suppliers. No problems at all with the product, been very reliable as long as a decent WLAN is available. Very happy with it, quality, price and performance
