The BMES 100 is a digital, intelligent boiler management system with built in programmer, designed to control single, small to medium sized commercial boilers. It is compatible with most makes and types of boilers using natural gas, oil or LPG. The system combines microchip technology with proven techniques to reduce energy consumption and CO2 emissions. Our Variable Thermal Response program measures system water temperature through electronic sensors on the flow and return pipes and accurately varies the system temperature to meet the demand imposed. Additionally the BMES 100 performs optimisation, weather compensation, variable thermal response, flow and return system temperature control, night temperature, hot water priority, two stage frost protection, digital programmer and optional security switch to eliminate unauthorised adjustments. Safeguards against back end condensation are also catered for, providing maximum energy savings whilst maintaining comfort conditions. The built in 7-day programmer provides up to two on/off periods per 24 hours with the ability to program variable on/off times for each day of the week.
