[adiplo]

I've just bought a Sunvic Select 107XL timeswitch to replace old broken mechanical timeswitch.
How do I have connect Hot Water Tank?
I now so Red and Black cables (live and neutral) should go to N & L.
But how I need to connect water tank?

See diagram.

How was the old timeswitch connected?

Did the old timeswitch control a thermostat or boiler?

Wiring diagram and tech info for the new timeswitch here.

Is it an immersion heater you want to control using this? If so this is the wrong kind of timer, it's not rated high enough to carry the current.

There are photos of old timeswith and water tank.
I think its immersion heater. (Or I wrong).

Yep, you've definately bought the wrong timer, what you have is a central heating programmer, what you need is an immersion heater timer (E7 with boost type, assuming you have an active economy 7 supply)
