The MCBA electronic controller regulates the boiler (start-up,safety,
modulation),the shunt pump and the heating pump in response to
hot water and heating demand.The MCBA offers numerous advanced
features :
- A large burner modulation range - down to less than 30%
- Extremely accurate hot water priority :even very small draw-offs
are immediately detected
- The hot water tank is always kept at an optimum temperature
- Excellent hot water performance
- Energy efficiency is optimised in both hot water and heating modes.
The HeatMaster 71 and 101
are fitted with the BG2000-M
modulating burner,which
has a metal fibre (NIT) flame
tube and smooth and near-
silent ignition and operation
- ideal for use in applications
where burner noise must be
kept to a minimum.
