Abstract
PURPOSE:To alert the user if the outdoor switch should be fused by detecting the outdoor side control voltage and transmitting the information whether there is a continuity over a signal wire to the indoor slide, and causing an indoor indicator to blink. CONSTITUTION:Signals from the main control 6 are fed while they are to cause the operation to cyclically go on and off. If ON signals are inputted, the outdoor control voltage does not drop if the contact points of a power relay are fused, and no reset signal is inputted to the outdoor control section 11. As a result, the I/F signal repeats a preset pulses, and, if they are found to be normal, the I/F signal is checked at every predetermined seconds after an enough time interval to allow the outdoor power source to be reset after the power relay is turned on. When the signal becomes 'Hi' level, the malfunction of the fused contact points is to be handled. In the malfunction handling mode, one of power monitor indicators is blinked in order to make it clear that the condition is not normal.
