3. Operation with timer

The CO

–consumption during the day (light phase) is determined primarily by the plants. In the

night (dark phase), the plants excrete CO

night time, it may even be harmful. The solenoid valve can be linked to a timer to meet these

specific requirements. An elegant solution is to connect the solenoid valve to the timer that

controls the lights. The valve is then switched on and off together with the light.

4. Operation with pH controller

This operation mode should be preferred in comparison to others. It is the most exact and

economical version. Only the exact quantity required is fed into the system. It balances the loss

that is, for example, caused by water movements and aeration. Fluctuations of the pH-values are

avoided by an electronic control. This is an advantage for the creation of a well-balanced

environment.

5. Operation with water

The Aqua Medic solenoid valve may also be used for the control of smaller reverse osmosis

systems. Some important points have to be taken care of to avoid mistakes and damages:

The reverse osmosis unit should not exceed a capacity of 150 l/d (35 gpd) of pure water. The

small opening of 2 mm will cause pressure drops and decrease the capacity, if used with larger

systems.

If used with tap water, the solenoid valve may be blocked by dirt and rust. In order to avoid

this, several precautions have to be taken:

The solenoid valve has to be connected between the sediment filter and the RO module to

protect it from clogging. The storage tank where the water is collected should have a safety

outlet to the drain. If used for marine aquariums, the evaporated water should not be refilled

directly from the RO unit. It is recommended to collect the RO water in a separate tank and to

provide the aquarium from this tank.

The solenoid valve may not be operated with sea water or pure water (reverse osmosis).

–gas. So it is not necessary to provide CO
