GCU : Gas Control Unit

Specifications

 Electrical Specifications :

  • GCU Current Consumption: 30 mA average  (The servo current consumption may be higher and will vary with different servos.)

  • 4.8V to 12V (any type of battery)

  • Polarity protection on Power input

  • Boiler Pressure Setting Range  : 0 – 6.3Bar

Items Supplied :

  • GCU control box

  • Boiler pressure sensor (Threaded ME ¼ by 40)

  • Red Alert LED

  • Blue Gas ON LED

Large LED’s - System Status/Fault Indicators visible from the pond side

Blue LED - System Status Indicator for Gas

  • LED Solid ON : Gas ON - Gas Servo open, gas burner heating the boiler

  • LED Blinking : Gas servo partially open – close to pre-set pressure

  • LED OFF : Gas on Pilot Light Setting – Boiler at set pressure

Red LED – System Status Indicator / Alert

Red LED Blinking : Alert

  • Low Input voltage

Red LED Solid ON : Safety-critical Alarm - emergency gas cut-off :

  • Critically Low Input Voltage – GCU cuts off the gas supply.

  • Pressure sensor connection failure - Pressure sensor not connected properly (this is a dangerous situation), the controller will no longer be able to maintain the boiler pressure – GCU cuts off the gas supply. 

  • NB The inclusion of a radio controlled on/off switch into the boiler pressure sensor line enables the user to remotely effect an emergency gas cut off.
