AUM 21 automatic wash basin tap with top regulation
The AUM 21 tap is an automatic wash basin tap with contactless control, with two water connections (hot and cold). The user can set the water temperature by means of the mixing valve with top regulation, integrated in the outlet arm.
By putting your hands in the basin (into the sensor zone under the outlet arm) you activate the control electronics, which is indicated by flashing of the sensor indicator, and the electromagnetic valves are opened immediately. If you remove your hands from the basin, the indicator goes out and the electromagnetic valves are closed and water stopped with a sufficient time delay. If the shading is permanent, the valves shut the water after 30 s. With the battery versions, the electronic program ensures that the electromagnetic valve does not open the water inlet unless the battery capacity is sufficient for its shutting.
The AUM AUM 21 tap is supplied with 12 V, 50 Hz from source of power supply ZAC.
The AUM AUM 21.B tap is supplied with direct voltage 6 V from AA batteries mounted under the basin.
