“This was a replacement for my unit which came with my boiler, went dead just outside of the 2 year guarnatee. Typical. Ideal told me I'd need an engineer to replace it. Bought replacement here instead. Easy set up myself, took a total of 20 minutes to complete set up. Good instructions in the box. Interface unit plugs in easily to boiler, press a button to pair with thermostat, and follow instructions on the screen. Download halo app, easy to follow on screen instructions. Easy to operate with or without the app. So far so good. Hoping it lasts longer this time. Happy with easy purchase process and very fast delivery.”
