Automatic - Running the system on automatic with only the automatic boiler working.

 

With the solid fuel boiler not firing, the Automatic system is under the control of the programmer, just the same as any normal automatic system. Read the programmer users guide for further help.

Heat leak radiator has circuit at all times

Red = Flow. Blue = Return. Orange = Preheated Return. White = Not flowing.

Function 5.

Pumped Circuit for the Automatic Boiler when in Hot Water Mode.

With the only the automatic boiler working, motorized valve no 8 is motored open to the automatic boiler, (closed to the solid fuel boiler). In hot water mode, motorized Valve no 10/17 is naturally open to the hot water cylinder, (closed to the radiators).

Status.

bulletMotorized Valve no 22---- Motored closed to prevent link up mode.
bulletMotorized Valve no 8------Motored Open to the Automatic Boiler. (closed to the solid fuel boiler)
bulletMotorized Valve no 9----- Motored Closed to shut off the Gravity Circuit.
bulletMotorized Valve no 10/17 Naturally Open to the Hot Water Cylinder. (closed to the radiators)

 

Red = Flow. Blue = Return. Orange = Preheated Return. White = Not flowing.

Function 6. 

Pumped Circuit for the Automatic Boiler when in Hot Water and Heating Mode.

As above, but in hot water and heating mode, motorized Valve no 10/17 is motored to mid position open to the hot water cylinder and radiators.

Status.

bulletMotorized Valve no 22---- Motored closed to prevent link up mode.
bulletMotorized Valve no 8------Motored Open to the Automatic Boiler. (closed to the solid fuel boiler)
bulletMotorized Valve no 9----- Motored Closed to shut off the Gravity Circuit.
bulletMotorized Valve no 10/17 Motored To Mid Position. Open to the Hot Water Cylinder & Radiators.

 

 Red = Flow. Blue = Return. Orange = Preheated Return. White = Not flowing.

Function 7. Pumped Circuit for the Automatic Boiler when in Heating Mode with Hot Water satisfied

When the hot water cylinder reaches optimum temperature (detected by the cylinder thermostat), motorized Valve no 10/17 is motored open to the radiators and closed to the hot water cylinder.

Status.

bulletMotorized Valve no 22---- Motored closed to prevent link up mode.
bulletMotorized Valve no 8------Motored Open to the Automatic Boiler. (closed to the solid fuel boiler)
bulletMotorized Valve no 9----- Motored Closed to shut of the Gravity Circuit.
bulletMotorized Valve no 10/17 Motored Open to the Radiators & Closed to the Hot Water Cylinder

 

Red = Flow. Blue = Return. Orange = Preheated Return. White = Not flowing.
