Gas Control Unit
GCU- Gas Control Unit
Sophisticated gas valve controller plus pressure sensor
Input power: 5V -15V
Input power polarity protection
ALERT Led and Gas On Led to give a feedback, when the modell is on the water
Pilot Light Set
Servo direction set
Proportional gas servo control advantages:
Reduce the amount of the used gas
It is using the gas in small amounts and at a slower rate, this prevents to reduce the gas tank cooling, which reduces the pressure in the gas tank and reduces the heat output which reduces the boiler efficiency.
Conclusion: The boiler efficiency will be better.
