Due to the boiler system being old and not applicable on the new windows internet server, we got the ICT team to help us run a wire directly from the motherboard to the 'site' office so now I can control temperatures. With everyday being classed as a 'winter' day, I changed the times the heating comes on so it is now 8:30am - 1:30pm. I have also changed the setpoint to 18 degrees so it only try to reach that heat. Early signs show it is working well. Attached is a picture of the setpoints. The 5 degrees is the frost setpoint and the 18 is the optimisation setpoint. It was previously set at 22.
