-===== Timers =====
-iAVs uses a timer that enable the water pumps to be run for a pre-determined number of minutes. We adjust the timer to ensure that the correct volume of water is pumped to the sand beds – taking account of variations in pump flow rate, head pressure and the hydraulic conductivity of the sand in use. Timers help to regulate water flow and ensure that plants receive adequate nutrients.
-Optionally, an iAVs can be run manually without the use of a timer.
-There are several types of timers that can be used in iAVS systems, each with its own benefits and drawbacks.
-==== Mechanical Timers ====
-Mechanical timers are a simple and inexpensive option for iAVS systems. These timers use a mechanical clock to turn the water pump on and off at set intervals. Mechanical timers are easy to install and require minimal maintenance.
-**Benefits:**
-- Inexpensive
-- Easy to install
-- Minimal maintenance required
-**Negatives:**
-- Limited programming options
-- May not be as accurate as other timer types
-- May wear out over time
-==== Digital Timers ====
-Digital timers are a more advanced option for iAVS systems. These timers use digital technology to provide more precise control over water flow. Digital timers can be programmed with specific on/off times, allowing for more precise nutrient delivery to plants.
-**Benefits:**
-- More precise control over water flow
-- Programmable with specific on/off times
-- Can be used with multiple pumps or valves
-**Negatives:**
-- More expensive than mechanical timers
-- May require more maintenance than mechanical timers
-- May require additional equipment (such as a power source)
-==== Smart Timers ====
-Smart timers are the most advanced option for iAVS systems. These timers use digital technology and internet connectivity to provide remote control over water flow. Smart timers can be programmed using a smartphone app or web interface, allowing for easy monitoring and adjustment of nutrient delivery.
-**Benefits:**
-- Remote control over water flow
-- Easy monitoring and adjustment of nutrient delivery
-- Can be used with multiple pumps or valves
-**Negatives:**
-- Most expensive option
-- Requires internet connectivity and additional equipment (such as a Wi-Fi router)
-- May require more maintenance than other timer types
-==== Solenoids ====
-Solenoids are an alternative to timers for controlling water flow in iAVS systems.
-A solenoid is an electromechanical device that controls the flow of water by opening and closing a valve. Solenoids can be used in conjunction with a controller to regulate water flow based on specific parameters such as time of day or moisture level.
-**Benefits:**
-- More precise control over water flow
-- Can be used with a variety of controllers
-- Can be used with multiple pumps or valves
-**Negatives:**
-- More expensive than mechanical timers
-- May require more maintenance than other timer types
-- Requires additional equipment (such as a controller)
-==== Water Pumps with Wi-Fi Access and Apps ====
-Water pumps with Wi-Fi access and apps are becoming increasingly popular for iAVS systems. These pumps allow for remote control over water flow using a smartphone app or web interface. Users can set and adjust irrigation schedules, monitor system performance, and receive alerts if there are any issues.
-**Benefits:**
-- Remote control over water flow
-- Easy monitoring and adjustment of irrigation schedules
-- Can be used with multiple pumps or valves
-**Negatives:**
-- May be more expensive than traditional water pumps
-- Requires internet connectivity and additional equipment (such as a Wi-Fi router)
-- May require more maintenance than traditional water pumps
