Bought Wi-fi Pro-e version which arrived promptly next working day with tracking updates until I received within 1 hour delivery slot.
Pro-e replaced my basic programmable 25 model that had given up working after 8 years. Quick 30 minutes for electrician to replace, test and commission new Wi-fi Pro-e.
App download and set up easy too and fully working electric underfloor heating again.
We are incredibly grateful that you took the time out to leave us a 5-Star review.
