*) The information complies with the provisional requirements of EU Ordinance 812/2013, mandatory as of September 2015
1) 1/2” water connection on request
2) Temperature increase e.g. from 15°C to 40°C
3) Limited flow for optimal temperature increase Can be adapted by the water volume adjustment
4) Observe regulations of the local energy supplier
5) Only the mains cable supplied may be used
6) Minimum permissible electrical resistance of the water at 15° C

Control panel
The control panel with the sensor key and three coloured LEDs serves to set the maximum outlet temperature to 35, 38 or 45°C
