SETTING THE PRE-SET MAXIMUM TEMPERATURE:
The SS3DT series of automatic controllers 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 your pre-set maximum 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 the 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’.
