Attention!
The live electric device!
Before doing any activities concerned with power
supply (connecting wires, installation of the device,
etc.) it is necessary to make sure that the regulator is
not connected to the grid!
Assembly and installation should only be carried out by
a qualified electrician.
Before activating the controller it is necessary to do the
measurement of the effectiveness of the resetting
electric motors, the boiler and the measurement
insulation of electric wires.
