Simmtronic installed the complete lighting-control system, having already fulfilled the lighting-controls contract on the shell and core.

The danger of scalding from hot water in baths in the communal homes of Dane Housing of Congleton in Cheshire has been eliminated by fitting Honeywell fail-safe thermostatic mixing valves. The TM200VP valves are approved to the TMV3 standard and ensure a safe hot-water temperature by mixing hot and cold supplies to a preset temperature. They also shut off the hot water automatically if the cold supply fails.

Old and leaking calorifiers on a 55°C hot-water circuit at a large army base have been replaced by packaged plate heat exchangers. Separate systems now supply domestic hot water and heating.
