For Viega, the maintenance of drinking water quality is a central issue. With the new “Hygiene-Assistant with Viega Hygiene+ monitoring function”, there is now a simple tool to monitor regular water exchange and temperature in the individual piping sections. A self-explanatory “traffic light” shows risks in the drinking water installation so that immediate action can be taken. Proper operation can be monitored perfectly with the new “Hygiene-Assistant”, problematic piping sections can also be quickly identified and samples can be optimised.
Compliance with the temperature margins for hot and cold water and the avoidance of stagnation are especially decisive for drinking water hygiene. The “Hygiene-Assistant with Viega Hygiene+ monitoring function” can show at a glance whether these criteria are in the “green range”: Illuminated symbols show the status of the water temperature and exchange on the electronic wall display using the signal colours of green, yellow and red.
Optimal monitoring
The information for the status display is provided by multi-functional sensors in the hot and cold water pipes. These sensors can also be fitted easily into existing pipe networks, for example at the corner valves of a washbasin or in sections that are critical to hygiene.
This makes the Hygiene-Assistant an ideal monitoring tool for buildings, in which proper operation is put at risk through interruptions in usage, such as in schools, hotels and hospitals. The use and temperature in pipe sections with rarely used extraction points can also be monitored perfectly.
Limits in accordance with the standard
The limits in accordance with DIN EN 806 and VDI 6023 are decisive for the status display of the “Hygiene traffic lights”. For cold water, the maximum temperature is 20 °C, while for hot water the minimum temperature is 55 °C. If the symbols are green, then everything is ok. An orange symbol means that the temperature is not in the optimal range or that usage dates back more than 72 hours. On the other hand, a red light signals an immediate need for action. The temperature is in the critical range or there has been no usage for seven days. By manually activating the water exchange, any negative impact on the drinking water hygiene can be effectively prevented.
Other features of the “Hygiene-Assistant” include connection to the building automation through potential-free contacts and the conversion to a collective display, which shows the proper operation. The status of all parameters can be read using a magnetic key as required. This display can also be selected for simple temperature monitoring of a circulation line.
Preset during manufacture, the Hygiene-Assistant can be put into operation immediately after assembly. Power can be supplied by either a mains adapter or battery. The display is available in black and white.
