PROBLEM TO BE SOLVED: To grasp delicate variation of a combustion state quantitatively by providing a flame lot voltage detecting means at an outdoor unit control section and displaying the flame lot voltage corresponding to the A/D table in a microcomputer in a hexadecimal format. SOLUTION: A display section 3 including 7 segment display units 6-8 and a flame lot detecting circuit 12 including a flame lot section 4 affixed to a burner section 10 are provided at a section 1 for controlling operation of the outdoor unit in an air conditioner where two indoor units are coupled with one outdoor unit. Control values and measurements of an operating state are collected at the control section 1 through communication lines 26, 27 with respective indoor units. Any one of a flame lot voltage display mode, a control value/ measurement display mode, a failure diagnostic mode, and the like, is presented at the display section 3 while being switched by a switch 24 and the flame lot voltage is displayed in a hexadecimal format in the flame lot voltage display mode. |
