3. Operation with timer
The CO
–consumption during the day (light phase) is determined primarily by the plants. In the night (dark
2
phase), the plants excrete CO
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 light. 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 economic 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 the capacity of 150 l/day (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
saltwater aquaria, 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 saltwater or pure water (reverse osmosis).
