Sensors and Safety Functions
•
Hot Water Delivery Thermistor:
Measures hot water temperature at the outlet valve (i.e. the ‘mixed’
temperature).
•
Heat Exchanger Thermistor:
Measures water temperature in the heat exchanger.
•
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 97ºC for a number of seconds.
•
Fusible Link:
Situated on the heat exchanger, electrical power supply is stopped if the temperature
exceeds 129ºC.
•
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 power surges.
•
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 blades) 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.
