How the air con system was controlled was of paramount importance to the site engineer, who required a control system that offered full integration of the bedroom's air conditioning system from a central point.
The hotel uses a key card reader in each bedroom for energy conservation so a further requirement was that the control unit should be compatible with this as well.
It was decided to use a centralised controller linked to a PC front end, as it provides both these operations from one source and enables the site engineer to access the system remotely. This also has the added advantage of individual control of the units, report generation, fault indication and group control to name just a few.
