Well made product and it does what it says on the tin.. Excellent
It arrived on time. Easy to install. Easy to follow instructions. It can be controlled manually or using the Smart phone, via Alexa I believe as well although I did not try this part it it. It looks good on the wall with a nice big display of Temperatures etc. It controls my new Worcester Boach boiler beautifully and build to lastest standard requirvments "Gas Plus".... It requires 5 core cable for the boiler end "link unit, and only 2 core at the main display unit on the wall... The old Thermostat 2 core cable will do the job. I recommend it.
