Sensors and Safety Devices
• Heat Exchanger Thermistor: Measures hot water temperature at heat exchanger outlet. If water
temperature reaches a predetermined limit, gas supply is stopped.
• Hot Water Delivery Thermistor: Measures hot water temperature at the outlet valve (i.e. the ‘mixed’
temperature).
• Flame Rod: Monitors combustion characteristics inside the combustion chamber. If the flame fails, gas supply is
stopped.
• Overheat Switch: Situated on the heat exchanger, gas supply is stopped when water temperature reaches 97°C for
a number of seconds.
• Fusible Link: Situated on the heat exchanger, electrical power supply is stopped if the temperature exceeds
129°C.
• Water Pressure Relief Valve: Safeguards the water circuit against excessive inlet pressure. Opens at 2060 kPa,
closes at 1470 kPa.
• Electrical Fuse: (3A glass fuse) prevents against over-current.
Surge Protector: prevents against over-current.
• Boil Dry Prevention: If water flow sensor detects no flow, gas supply is stopped.
• Combustion Fan Speed Sensor: In case of combustion fan defect (no rotation of fan) gas supply is stopped.
• Temperature Cutout: If the delivered hot water temperature rises above the required delivery
temperature for a number of seconds, the gas supply is stopped.
