Hi guys.

i need to know how you can imagine this "manteinance mode " in my P4

i need to prepare salt mix with RO water directly into reservoir tank of RO.

So i need to program a heater and a pump for mix it for 5/6 hours and meanwhile stop 2 level sensors (1 for ATO in sump and 1 for ATO from RODI plant) there are present in this tank.

my idea is prepare right amount of salt, dose in the RODI tank that i normal use for ATO ,let it mix and after when i take off same amount of water manually from my tank i fill into sump all brand new salt water.. after that level sensor can be new active and begin the operations for refill with fresh RODI water the tank..

is clear?

thank you
