About 'Modulating Control' and 'Open Therm',
two new buzz words.

The controller will measure room temperature, or outside temperature in the case of Weather Compensation, and calculate the desired flow temperature depending on the current and desired temperature and time settings.

The boiler flame can be modulated accordingly, keeping the living space always at its optimum temperature.  At the boiler an intelligent interface will sense and control, among other things, the burner, heating circulation pump, domestic hot water pump and valve and the mixing valve. Optimum Start is also available if required.

With the growing pressure to improve energy efficiency, customers will expect to be offered the most effective solutions, that give them long term savings It is inexcusable to sell a customer a modern energy-efficient boiler and then deny them the full benefits of a modulating controller, especially when OpenTherm boilers and controls are now readily available in this country.
