OPERATING INSTRUCTIONS - SS3DT AUTOMATIC CONTROLLER
The SS3DT series of automatic controllers are microprocessor controlled. They are used to control
the heating of your pool/spa from your solar collector.
INSTALLATION:
Your automatic controller should be mounted on a wall close to a power outlet and both your filter
pump and solar pump. Where possible, it should be located to minimise exposure to weather.
1: Plug your solar pump into the point provided on the underside of the automatic controller.
2: Plug your filter pump into the point provided on the underside of the automatic controller.
NOTE: If your filter pump is plugged into a salt chlorinator, leave the filter pump plug in place and
plug the salt chlorinator into the socket labelled “filter “ underneath the automatic controller.
Make sure the salt chlorinators time clock is switched to manual. Do not leave it on
automatic.
3: Set the SS3DT time clock to the current time of day. The clock runs on a 24 hour system.
4: Set the timer for an appropriate filtration time. Recommended filtration times are;
Summer: minimum of 6 hours per day. ie: 10:00am to 4:00pm.
Winter: minimum of 2 hours per day.
(See the clock setting diagram for further instructions)
5: Plug the automatic controller directly into a power outlet.
6: Turn the power outlet on so as power is supplied to the automatic controller.
7: Press the ON button for a few seconds (this button has a built in time delay system). Once the unit
is on, a green light next to the ON button should be lit.
8: Ensure the automatic controller is set to the AUTO mode. This is evident by the green light next to
the AUTO / MANUAL button being lit.
HOW DOES IT WORK:
Your automatic controller has two temperature sensors. One on the roof sensing the temperature of
the solar collector, the other in your plumbing system sensing your pool water temperature.
When the temperature of the collector is 7°C greater than that of the pool water, the automatic
controller will turn your solar pump on. This will push water through the solar collector, in turn heating
your pool.
The automatic controller will turn the system off for one of two reasons.
1: The temperature of the roof sensor drops to within 2 °C of the pool water sensor. Therefore no
significant heat gain can be achieved.
2: The pool water has reached its pre-set maximum temperature.
It is important to understand that your solar system operates simultaneously with your filtration
system. You cannot run your solar pump independently. However, you can run your filtration system
without running the solar system.
3: The time clock component of your SS3DT controls your filtration system.
4: The solar component of your SS3DT is built with a system that ensures that the solar pump never
runs on its own.
