Abstract
A control method and mechanism for switching heat generating equipment which requires the steps of: PA1 positioning a control box containing a block positioned within an insulating material in association with a building; PA1 maintaining the block within the control box at a first pre-set temperature (T1) during shut down conditions of a heating system incorporated within the building and which is to be operated by the control box; PA1 deactivating at a pre-determined period prior to the time the building is to be occupied a heater which has maintained the block at its pre-determined temperature; PA1 allowing the block to cool to a pre-determined temperature (T2); and PA1 activating a main control mechanism or switch of the heating system when the block has cooled to the pre-determined temperature (T2) so that the building is heated to reach a desired temperature at start time for use of the building. The pre-determined period is dependent upon the thermal properties of each building and the output of the heating equipment employed in the building. By varying either the pre-determined period and the preset temperature T1, the construction of the building, or the output of the heati…
