Full Autonomy

With the same innovative functionality of the entry level Lite LTE system, PWR also offers full plant room automation. PWR instinctively detects its global location, then adjusts and controls the filtration cycles to operate on the most economical tariff available.

Autonomy vs Automation

Although both actions sound the same there is a distinct difference. An ‘automation’ system will simply follow reactive pre-programed instructions to carry out a specific task, whereas a full ‘autonomy’ Sentinel® system will be intelligently proactive to carry out multiple tasks with unique outcomes each time.

We can consider the example of ‘backwashing a swimming pool filter’ using both scenarios:

An ‘automation’ system may backwash the filter every week at 12pm for 3 minutes and will repeat this action regardless of whether the filter actually needs the function or not.

An ‘autonomy’ Sentinel® system however will take data from digital pressure sensors attached to the filter and process this information through its computer to determine the best course of action to take. This results in the filter only being backwashed when it is required (which could be on any day or time), and only for the required duration. This innovative technology results in the perfect performance of the filtration system and will also save water in the process, potentially providing economic benefit for properties with a water meter installed.

Sentinel® also automates other aspects of plant room maintenance. This includes purging of pre-filters; scheduling UV and Ozone generation; control of pump invertors for variable speed filtration; dosing tank agitators and much more.

Choose between Chlorine…

Nitro NXT is Sentinel’s Advanced Chlorine product specifically formulated for use with Sentinel® systems. It incorporates broad spectrum algaecide, high octane biocide, clarity control and comfort enhancer. This ensures a continuously clean, safe and crystal clear bathing environment.

With chlorine as your preferred sanitiser, the reading is displayed in Millivolts (mV) and is an overall measurement of Oxidation Reduction Potential (ORP). The ideal ORP range for chlorine in a domestic swimming pool is between 650 mV and 750 mV.

All Sentinel® systems have the capability to test and dose both chlorine and non-chlorine sanitiser types, and can therefore be switched instantaneously with just the click of a button.

…OR
Active Oxygen

Fusion OH- is Sentinel’s non-chlorine Active Oxygen product specifically formulated for use with Sentinel® systems. It incorporates broad spectrum algaecide, high octane chlorine-free biocide, clarity control and comfort enhancer. This ensures luxuriously soft water with no chemical odour, ideal for bathers with skin or respiratory sensitivities.

Chlorine Free Active Oxygen is the sanitiser of choice for bathers with skin or respiratory sensitivities.

With non-chlorine Active Oxygen as your preferred sanitiser the reading displays a timer animation. This shows that the system is injecting a predetermined dosage of Active Oxygen on a timer basis.

All Sentinel® systems have the capability to test and dose both chlorine and non-chlorine sanitiser types, and can therefore be switched instantaneously with just the click of a button.

Smart Storage

In addition to dosing directly from 30 litre chemical containers, we also offer a wide range of intelligent dosing tanks depending upon the dimensions of your swimming pool and dosing requirements.

All Sentinel® dosing tanks are designed to keep your swimming pool sanitised and safe for periods of 3, 6 or 12 months between each tank re-fill. This results in less service visits from your Swimming Pool Technician or the inconvenience of changing the chemical containers yourself.

Agitator systems can be fitted to tanks to give stored chemicals a little boost prior to dosing.

All dosing tanks incorporate several safety features including lockable lids, non-return suction lances and digital level sensors. Chemical level alerts are sent ‘Over The Air’ (OTA) direct to your email or Twitter account and will include a date and time of when we intend to replenish your chemical storage tanks. The timing of this visit can be adjusted for your convenience.

Intelligent Dosing

Intelligent Dosing

Sentinel® intelligent dosing pumps adapt speed and dosing velocity according to in-line system pressures, ensuring correct chemical dosage is achieved. Dosing pumps have variable speeds which are set during Sentinel® installation. They then adjust and control themselves as necessary during daily operation.

Sentinel® enforces strict hierarchy technology to each chemical dosing pump. This ensures no two pumps ever run at the same time and removes any risk of in-line chemical mixing. This also creates a safe environment within the plant room and for the bather.

Over the Air
System Updates

As the Sentinel® system is connected to the internet, this allows for convenient ‘Over The Air’ (OTA) system updates. This includes updating to the latest security firmware, system software upgrades, and even micro calibrations to the sensor suite to ensure your water analytics remain exact.

By engaging the ‘Upgrade’ button on your Sentinel® system you instigate a request for enhanced features, e.g. upgrading from LTE to PWR advanced functionality, through to a complete PWR+ system. You will be asked to confirm your request and make payment. The upgrade is administered remotely by Sentinel® Customer Service and complete within 24 hours, after which all enhanced features will be available and ready to use.

Updating with new software iterations ensures your Sentinel® system improves with age… it keeps getting better!
