Micro-processor Controller Electronics

The Malaga 4 water heater is equipped with the latest Propex electronics for accurate digital control of the heaters operation and safety functions. The switch panel features a 3 position switch for selecting either “gas only” or “gas and 230v”. If you want to use the heater on 230v only, you simply switch off the gas tap that supplies the heater whilst leaving the switch in the “gas and 230v” position. The yellow L.E.D. on the switch panel lets you know when the gas burner is operating and also, by flashing a certain amount of times, indicates various fault conditions.
