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.
Wireless remote sensors make the Merley easy to install, while the even use of boilers, achieved by the controller changing the lead boiler regularly and preventing re-firing too quickly, reduces wear and tear.
Relaying fault codes from boilers to its display screen, the Merley alerts users when a fault occurs and automatically replaces boilers at fault to provide continuity of heat and comfort.
While the Merley is primarily a boiler sequence controller, it can also manage the operation and comfort requirements for a single heating zone as well as the production of hot water via a single DHW calorifier.
“Good control of primary heating and hot water plant and distribution systems is a vital part in achieving low energy consumption and reducing carbon emissions,” said Bob Walsh, Hamworthy Heating’s Technical Director.
“In our commitment to improving heating system controls, the Merley controller has been developed with what we believe the principle requirement of any good control system should be, to provide heat and hot water only when and where it is needed and at the right temperature,” he added.
A range of options ensures the Merely can deliver control solutions for a wide range of buildings and heating applications. Matched for use with Hamworthy’s Fleet boiler range, the controller also accompanies the manufacturer’s existing Wessex ModuMax, Purewell VariHeat and Sherborne SE boiler ranges.
