Select your desired temperature in degrees Centigrade from 26 to 45.

Note: You can also adjust the water temperature as you shower.

Select your desired flow rate in liters/minute. Now the shower will start. You may have to wait a few seconds until the cold water is purged from the hot water line.

Now your SSF is controlling the water temperature and flow just like you selected.     At any time you can make changes as you desire

After you finish showering set the flow to zero and the system will shut down.
