TEMPERATURE
CONTROL
The unit has been designed to provide the cooling load required whilst optimising energy
efficiency at all times and as such will take advantage of free cooling whenever
available. If the free cooling available cannot satisfy the required full cooling load, DX
(mechanical) cooling is used to supplement the output.
The
microprocessor maintains the return air temperature set-point
temperature by sensing the return and outdoor air temperatures. The Economiser
damper positions are modulated as necessary to optimise fresh air free
cooling operation.
