<p>PURPOSE:To reduce the number of lamps and remove the complication of the structure and simplify the structure and manufacture the device at a low cost by displaying the deficiency of space heating water using an already existing confirmation lamp provided in a remote control panel. CONSTITUTION:The device comprises a space heating operation switch 51 for carrying out the start and stoppage of the space heating operation, an operation confirmation lamp 52 for confirming the space heating operation, and a space heating remote control panel 50 provided with a combustion confirmation lamp 53 for lighting and displaying the combustion by a combustion mechanism. Fault displays of two kinds, that is, a case where combustion cannot be conducted due to a fault in a combustion mechanism or the like and the space heater enters into a safe operation state, and a case where water within an expansion tank 22 runs short and a circulation pump 23 is put into an idle operation state, are conducted by two kinds, long and short, of flickering displays using the combustion confirmation lamp of the space heating remote control panel. For this reason, two different faults can be informed to the user in an easily discriminating manner by one lamp without increasing the number of lamps. Further, since it is possible to reduce the number of display lamps, the manufacture cost is low and the structure is simplified.</p> |
