Supreme Heating SS3DT Operating Instructions Manual

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 colle ctor.

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 cl o c k to the current time of day . The c l ock runs on a 24 hour syst em .
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 automat ic controller will tur n 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 bui lt with a system that ensures that the solar pump never
runs on its own.

SETTING THE PRE-SET MAX I MUM TEMPERATURE:

The SS3DT series of automat ic controll ers allows you to set a maximum desired pool water
temperature.

1: Press the SELECT button once. This will change the display from the current pool temperature to
your pre-set maximum temperature.
2: Use the UP and DOWN buttons to adjust you r pre-set max imum temperature. The display will
return to the pool temperature after a few seconds.

NOTE: Pressing the SELECT button twice will change the display to current solar collector
temperature.

SET TEMPERATURE / AUTO SAMPLING
If your pool has reached its PRE- SET temperature it will activate the automatic sampling mode.

Because the POOL sensor is located in the pipework around the solar pump and not in the actual
pool itself it can heat up quicker and give a false reading. The purpose of this mode is to avoid
inaccurate pool temperature readings and create more accurate running times. Sampling will occur
every 2 hours and the SS3DT will turn on the pump for 5 minutes whenever the ROOF temperature is
above the SET temperature. If the ROOF temperature is below the SET temperature, the unit will not
sample avoiding night time operation.

COOLING (TROPICAL MODE)

This function can be used in Tropical climates where the pool temperature is too hot. Of a night when
the ROOF temperature is 7° C or more below the POOL temperature it will turn on the pump and
circulate water and cool it to the SET temperature if possible. It will turn off if the SET temperature is
reached or if the ROOF temperature rises to within 2° C of the pool water temperature.

To activate Tropical mode – Holding the SET button for 5 seconds while displaying the ROOF
temperature will allow cooling mode to be activated. Up and down arrows are used to change this
setting and the SET key to exit. (Or wait 60 seconds)

The possible settings are:
“H” for heating only.
“HC” for heating and cooling (Tropical)

SENSOR DIAGNOSTICS

The following errors are now displayed along with flashing lights to indicate a faulty sensor or cable.
Flashing “OC” Open circuit (possible break in cable)

Flashing “SC” Short circuit (possible damaged wires making contact)
Note: the relevant flashing sensor needs to be selected for the above messages to be seen.

WHAT ELSE DO I NEED TO KNOW:

1: It is recommended that you use your solar system during the solar season only. The solar season
usually begins in mid September and finishes around May. During this time you shouldn’t have to
do anything except set your pre-set maximum temperature. The automatic controller will do the rest
for you.
2: At the end of the solar season simply turn t he system off by pressing the SENSORS OFF button.
Reduce your filtration time on the time clock to two hours per day. It is important to leave power
supplied to the unit. Whilst the unit is turned off it will operate the solar pump for ten minutes each
day. This stops any stagnation occurring in the system and also keeps the pump in good order.
This is called ‘winter mode’.
