ABSTRACT:
An electronic memory panel assembly controls the operation of a portable water purification system which has a reverse osmosis unit having an inlet. The assembly includes a solenoid device with piping having an inlet end fitting for attachment to a source of water to be purified, an outlet end fitting for attachment to the inlet of the reverse osmosis unit, a normally closed valve in the piping, and a solenoid having terminals which when activated will open the valve to cause automatic operation of the purification system. The assembly also includes a control device for automatically controlling the solenoid in accordance with predetermined criteria. The control device has a timer, a relay 32, a first pair of leads connecting the timer, and the relay 32, a second pair of leads running from the relay 32 to the solenoid terminals, and a third pair of leads, one of which is at the same electrical potential as one of the first pair of leads and the other of which is at the same electrical potential as one of the second pair of leads. The third pair of leads is connectible to a power source. The timer determines when the solenoid is activated and deactivated.
