Title: +038=370.101-OE002T_02-Multical 801 Energimåler Kamstrup - Teknisk beskrivelse.pdf
In addition to the above-mentioned functions, MULTICAL 801 can be connected to the pulse signal from the cold- water meter of the house. It can thus monitor the cold-water consumption. Possible running cisterns, untight heating spirals of tap water tanks or other untightnesses will cause pulses to be received from the cold water meter 24 hours a day. If MULTICAL 801 does not register, e.g. at least one continuous hour/day without pulses from the water meter, this implies a leakage in the water system and an alarm will be sent via remote communication.Cold water leak surveillance (VA)N= 0 1 2 3Constant leakage at no consumption (pulse resolution 10 l/imp) OFF 20 l/h (30 min. without pulses) 10 l/h (1 hour without pulses) 5 l/h (2 hours without pulses)Note: N=2 is the default value in connection with leak surveillance. Increased sensitivity, e.g. N=3, can only be achieved by means of METERTOOL. Info codes for leakage/burst are only active when M > 0 eller N > 0 respectively.
