1.0GENERALINFORMATION

1.1DESCRIPTIONOFAPPLIANCE

1.1.1 General

The FS400 or FS525 model is a gas red, low NOx, dual burner boiler system, for the supply

of low temperature hot water for space heating and primary hot water. The Sirius FS range

of boilers have extensive user programmable controls which can be congured to control

space heating, hot water, Solar and Primary circuits.

Fully automatic electronic controls are integrated into the boiler, with a wide range of

control and sensor options available. An outside temperature sensor is included as standard

to support full temperature compensated heating circuits. The controls also provides volt

free inputs to control the activation of heating and hot water circuits, a 0-10v input to

control demand, and volt free outputs to indicate burner on and fault. All of which can be

used when connected to an external BMS system.

Each burner module consists of a stainless steel combustion chamber, premix burner,

modulating fan and gas valve, ignition and ame detection electrodes and common ow and

return NTC sensors for accurate boiler management control. Fully premixed, radiating,

modulating burner, integrated with gas valve to deliver precise gas/air mixture throughout

the full modulation range.

A common combustion air intake manifold, takes air from the boiler room (type B23). An air

non-return valve gas mixing system is integrated into the air/gas mixture supply of each

burner, to ensure that ue products cannot contaminate the air supply, when the other

burner is not in operation. A separate electronic management system, monitors the position

of this air ap to ensure safe operation during all stages of boiler operation.

The safety and operation functions of each burner are managed by micro processor

controlled circuit boards, one for each of the burners. The Master ontroller also acts as the

cascade controller, switching/modulating the burners according to the demand and readings

from the systems sensors. Control is performed using comparison parameters between the

requested temperature and the global ow temperature.

1.1.2 Control Logic

At full demand, each burner is ignited one at a time, until both burners are operating at full

output. As ow and return temperatures increase, both burners will begin to modulate down

together, until both are operating at minimum input rate.

As ow temperatures begin to approach the calculated set point, one of the burners will

stop, leaving the other operating at minimum input rate. This will continue until both

burners have stopped and temperature ow requirements have been fully satised.
