I have 3 pieces of water purification equipment in my pump room (long story). A water softener, peroxide injector, and a tannin remover. Each of these has an IWT-165 controller (Independent Water Tech). They all do their backwash activity at different times under different conditions (volume, time, etc.). My problem is with the salt consumption. We are only around half-time, and there are only two of us usually there, so there is a lot of salt usage that is unnecessary (40kg/mo.).
I can easily use my UPB infrastructure to turn the controllers off when we are away. Actually, my plan is to have them disabled when the alarm system is activated. However, the only way I can see to do it is to drop the power to the controllers. The problem is that the capacitor/battery backup is only good for 48hrs.
So, I had the water contractor provide me with a test unit hoping that I would be able to find the capacitor/battery and keep it charged. He suggested I just disengage the motor circuit on the controller. Turns out I can do that, but the controller knows its disconnected and sets off an audible alarm (and halts the backwash).
The question is; Does anyone have any information or suggestions? I tried finding the IWT-165 schematics on-line but they are not available.
Many thanks,
