New boiler sequence controller

Achieving good control of multiple boiler installations is essential to meet the demand for high system efficiencies and to exceed the Building Regulations recommended minimum standards.

To help effectively manage multiple boiler modules, Hamworthy Heating has introduced the Merley, the latest generation boiler sequence controller, which is perfectly matched for use with the leading manufacturer’s latest Fleet boiler range.

With the Merley, Hamworthy Fleet boilers can be controlled to share the load between multiple boiler modules in the most efficient manner possible.

Using proven, reliable, Siemens controls platform technology, the Merley provides efficient boiler cascade control for up to 16 modules, based on time and temperature requirements.

Supplied fully assembled, the Merley’s adaptable control capability allows integration of the sequence controller with most commercial heating system designs, as a standalone device or as an integrated part of a more dynamic building management system.

With multiple boilers a well established approach to heating commercial buildings, the Merley controller offers numerous control strategies, providing user programmability to suit building occupancy. Time and comfort control, time clock and optimiser, variable or constant flow temperature, night set back and frost protection are all included.
