PURPOSE:To provide a temperature control device for a comfortable hot air heater by a method wherein a temperature where an operation of the heater is changed from a low output operation to a high output operation is composed of a temperature where an operation is changed from a high output operation to a low output operation, a temperature where the operation is to be terminated and a temperature where the stopped operation is restarted, respectively, in an order of higher temperature. CONSTITUTION:A system has a burner 1, air blowing fan 3, indoor temperature sensing means 4 and a comparing means. The comparing means sets the temperature in sequence from the higher order, i.e. TOFF, TON, TL and TH where a temperature for terminating the operation is TOFF, a temperature where the terminated operation is restarted at a low output operation is TON, a temperature where a high output operation is changed over to a low output operation is TL, and a temperature where a low output operation is changed over a high output operation is TH. After the temperature is reached to the value of TOFF and the operation is once terminated and the temperature is reached to the value of TON as the room temperature is decreased, the operation is restarted under a low output without fail. Due to this fact, when the room temperature is increased even under a low output operation, it is possible to eliminate irrationality of restarting operation with high output. Due to a repetition of starting of low output and termination, a low fuel consumption can be attained. |
