<p>PURPOSE:To prevent useless energy consumption by setting an allowable continuous electricity conductive period, activating a load after the interruption of the load and a prescribed pause period and preserving the inside of an automatic vending machine at a sellable temperature. CONSTITUTION:The title device consists of a load 1, a temperature regulating thermostat 2, a thermal protector 3, a relay X, a continuous drive supervising timer T1 and a reactivation preventing timer T2. When the temperature regulating the thermostat 2 is troubled, electricity is conducted to the load 1 during the allowable continuous electricity conductive period H1 after an interrupting period H2 to be the pause period. Consequently, the continuous electricity conductive period H1 and the interrupting period H2 are suitably set, the inside of the machine can be maintained at the desired temperature. Thus, the useless energy consumption can be prevented.</p> |
