Melnor Digital Water Timers

Before introducing the wifi enabled water timers, there are earlier versions, the digital water timers which are also a delight to have if you do not have internet access. There are 2 types with 3 models each. There is the Hydrologic line and the Aquatimer line. However, the aquatimer line has also been modified. We will discuss that when we talk about AquaTimer Water Timers below!

Each type has a companion soil moisture sensor to help save water even more by not watering when there is still enough moisture in the soil. Here is a brief look at these water timers.

Melnor HydroLogic Water Timers

The Melnor Hydrologic water timers come in 3 versions. There is the 4-zone, 2-zone and 1-zone. All these are easy to install, setup and program. They come with a big enough LCD display screen to see what you are doing. The inlet connects to the faucet and depending on the number of outlets (for zones) your timer has, you can program each zone independently.

Despite that you would have connected the Hydrologic water timer to the faucet, you can still operate the faucet manually with a simple twist of a knob. Apart from programming, there is a breeze, they retain their memory even when you remove the batteries.

Melnor 53280 – HydroLogic 4-Zone Digital Water Timer
The Melnor 53280 is a 4-zone digital water timer, meaning from one device you can control 4 different zones as if you had 4 different hoses or sprinklers. Each zone is independent of each other and you can connect it to anything you normally would.

That is to say from one outlet you can connect the sprinkler system for the lawn, another the drip-irrigation system for the garden, etc. You set the times and lengths of how long and when to water. Each zone independent of the other.

Melnor 53100 – Hydrologic 2-Zone Digital Water Timer
The Melnor 53100 will give control over 2 zones and the installation, programming, and setup are the same as with the 53280 model. The difference between the two is that 53100 has lesser zones to water.

Melnor 53015 – Hydrologic Digital Water Timer

The Melnor 53015 controls one zone and more like a water timer without the benefit of giving you control over different zones. However, it still is operated like the above.

You can program for individual days of the week, works with Melnor Hydrologic Soil Moisture Sensor to help you save water by not watering if the soil is still moist enough. It also has a manual rain delay feature so that if there is a forecast of rain you can skip a cycle.

Melnor Hydrologic Soil Moisture Sensor

The Melnor 15339 Hydrologic Soil Moisture Sensor is a device that you can use to save even more water by telling the timers when not to water even when the settings allow watering. This soil moisture sensor, model 15339 is compatible only with the Hydrologic Digital Water Timers, not the Aquatimer range.


Melnor AquaTimer Water Timers

In the same way as the HydroLogic Water Timers, they work the same way. There is 3 types – 4-zone, 2-zone, and 1-zone. They are not very different in how they operate from the above. The big difference that one has to be aware of is compatibility issues with soil moisture devices and that there are two versions that co-exist and this seems to create problem and confusion.

Melnor Water Timer Problem

There is a problem with the Melnor aquatimers in that they can be confusing as to which is which. Here are the two versions of the AquaTimers;

Melnor Advanced Digital Aquatimer Water Timers – this version is higher than the one below. Though it seems like it is a higher version, it is not compatible with Melnor 3300 Automatic Rain Delay And Soil Moisture Sensor as is with the version below. To recognize this model you find that its model numbers have 5 digits.

Melnor Original Digital Aquatimer Water Timers – This is the “original” version in comparison to the version above. this version can be adapted to make watering automatic by coupling it with the Melnor 3300 Automatic Rain Delay And Soil Moisture Sensor. This seems to be the main problem with these Melnor water timers.

Another important point to note with this line is that they have predecessors which can be easily confused with the current versions. The updated models of the AquaTimer Water Timers bare 5 digit model number while their precessors bare a 4 digit model number.

In other words, the latest version of a 4-zone AquaTimer is 33280 while the earlier 4-zone Aquatimer model number is 3280, notice the extra 3 in the newer model. This could be confusing at times but the 33280 is the updated version of the 3280. They also do not look the same as in design. The image below is for the older version of the Aqua Water Timers!

It also appears the older version was not as easy to program as the newer version. The buttons on the newer version a smoother and softer to press. Watch the following video for troubleshooting….

AquaTimer 4-Zone Digital Water Timer – Melnor 33280

The Melnor 33280 has 4 outlets allowing you to have up to 4 zones that you can water from one faucet. With this timer, you can water up to 24 times a day and this is great when you have water plants that tend to lose water quickly. With this water timer, you do not need to buy any extra valves, each outlet operates independently.

It comes with a metal coupling nut with rubberized grip to avoid slipping if you have wet hands. It also has a large enough LCD screen to let you see what you are doing without a struggle.

AquaTimer 2-Zone Digital Water Timer – Melnor 33100
The Melnor 33100 allows you to water 2 areas from 1 faucet and works the same way, in terms of programming, as the 33280 model. The LCD screen is still large enough and programming is a breeze.

AquaTimer Digital Water Timer – Melnor 33015
The Melnor 33015 has only one outlet and is ideal if you do not have zones that need different watering requirements. You just program it to water according to a schedule.

Melnor 3300 Automatic Rain Delay And Soil Moisture Sensor
Melnor 3300 is an Automatic Rain Delay compatible with the AquaTimers discussed above. The purpose of this device is to halt the watering if there is enough moisture in the soil. If it has just rained or raining you don’t have to worry, the watering will stop.

Why You Should Use Automated Melnor Water Timer

Automatic electronic water timers, especially wifi enabled, will free your time and save you money. Once you have installed one in your house you will have time to do other things or simply enjoy yourself relaxing.

Once you have setup everything like connecting the hose faucet, programmed the device to schedule watering of the different zones, you can sit back and let the watering be done for you.

The Melnor RainCloud is the latest version of the Melnor water timers. The Rain Cloud is SMART to the extent that you can talk to it. It integrates with Amazon Alexa.
