Optimising Controllers Wet System

Optimising controllers realise fuel savings by adapting boiler firing and heat distribution patterns to match variations in heat demand. They are available either as standalone units for retrofitting to existing boilers, or as modular units that can be integrated into boiler, burner or other control systems.

Both standalone and modular type optimising controllers are eligible for Enhanced Capital Allowances, provided they are microprocessor based and incorporate the following minimum features:

	Independent zone, timing and temperature controls such that the space temperature of each functional area can be separately controlled in accordance with occupation patterns
	Facilities for users to "temporarily override" pre-set timings during unusual occupation hours
	"Automatic night set back" and controls to prevent condensation and frost damage
	Optimum start and weather compensation for each zone controlled
	Tamper-proof protection to prevent the optimiser from being switched off
	An algorithm that periodically optimises controller operation automatically

Additionally, optimising controllers may include many other useful features such as:

	Independent control of domestic hot water circuits
	Boiler inhibit, sequencing and/or burner controls
	Interlocks to prevent simultaneous heating and cooling
	Remote monitoring and control interfaces
