The correct positioning of sensors is important to maximise the efficient running of your Solar Controller;
Pool temperature readings can vary or appear to be incorrect for the following reasons;
Refer to: Q3. What’s the difference between “Pipe” & “Pool” temperature readings?
Roof temperature readings can vary or appear to be incorrect for the following reasons;
Both Pool & Roof temperature readings can be affected by electrical interference particularly when sensor cabling is installed too close to electrical cabling or electrical pool equipment. (eg. pumps or high voltage equipment)
Pool heating can sometimes be interrupted or prevented for the following reasons;
Pool pumps can sometime loose “prime”. This basically means that water is not properly circulating. If your Solar pump losses prime then, water from your pool is not properly circulating through your pump and heating system (eg. Solar Collectors on the roof) and back to your pool. Causes can be varied, but should this happen, water can remain circulating within the pump and can get heated to high temperatures. This then heats up the Pool sensor which tricks the controller into thinking the Pool has reached or exceeded the desired set temperature. Refer to: Q7. How Do I “prime” my pump?
While it’s best to refer to your pump’s instructions and/or supplier, the basic process is;
If unable to prime pump after performing the above steps 3-4 times, it’s likely that your pump or other pool infrastructure needs servicing.
Dontek controllers draw very little power themselves and are unlikely be directly responsible for such events. The tripping of house electrical circuit breakers or safety switches can usually be attributed to a faulty pump, a faulty power socket or a circuit overload.
To confirm if the Controller is at fault;
If the house electrical circuits do not trip, then the problem is likely to be with the pump, the power socket, or a circuit overload. Contact your pool installer, local pool or electrical professional.
If the house electrical circuits do trip, then the problem is likely to be with the controller. Refer to: Product Servicing
