Children spoke with Caretakwer about boiler controls and if the temperature could come down further and heating coming on later and going off eariler. Caretaker adjusts the temperature and timing. he moved the timings with heating coming on at 7.30am and kept moving the time by 20mins every day until their was a noticeable chill in the air. The heating was turned off by 4pm as most staff left the building by then.
