We just recently moved into our house and now it's heading into winter. The programmes are set for the week and weekends but at 5am I have notice the furnace kicks in. On the screen it says "Following Scheduled Recovery". What is that and how do I stop if from doing that. The furnace isn't supposed to kick in till 6.30am or if the house drops to 15C. But nope it's kicking in at 5am every morning with the house at 19C. Wasting too much energy.
