Abstract
PURPOSE:To make a remote control box and a gas appliances which are connected by a two-core cable be remote-controllable without damaging various functions by a method wherein a standby display and an ignition display are conducted by AC signals having a respective frequency while a start instruction and a temperature designation, and an alarm are conducted by DC signals with different polarities from each other. CONSTITUTION:When a power source SW is closed, an AC voltage of the same frequency as that the power source occurs on a secondary coil T2 and a standby lamp L1 is turned on. Then, when a start switch S1 is closed, the potential at point A falls, this fall of potential is detected by a start discriminating circuit 7 and outputs of a DC power source 2 are supplied to a combustion safety circuit 3. At this time, if a temperature measuring bridge composed of a variable resistor R13 and a thermistor TH defects a temperature under the designated one, an ignition sequence is conducted. When a pilot is ignited, a switch S2 is closed in an ignition signal generation circuit 8, a full-wave rectifier circuit D2 operates by an output of a vibrator 9 of high frequencies and turns on an ignition lamp 12. Thus, the tool side and the control board are connected through two wires only.
