5) SOLAR MODE
MODE MODE MODE
SUMMER MODE AUTO INTER MODE TROPICAL MODE
SUMMER MODE is the normal operation of heating the swimming pool.
TROPICAL MODE is selected if you wish to cool the swimming pool, the solar pump will run if the roof temperature
is colder than the pool until SOL LIMIT is o tained; note that this is most likely to occur at night. Selecting tropical
mode also ignores solar lockout times and lock to filter settings.
WINTER MODE, when selected you will e prompted to select the start month of winter and the start month of
summer, the purpose of the winter mode of operation is for off-season maintenance or if pool heating is not
required (AWAY MODE). This is a etter option than turning off the controller as it will flush treated pool water
through the solar system as well as prolong pump earing and mechanical seal life. If AUX. HEATER is set to OFF a
3 minute flush of the solar matting occurs etween 10:00 and 16:00 providing the roof temperature is equal or
greater than the pool, ut if that condition does not occur a solar system flush will e forced to occur at 16:00.
If AUX. HEATER is set to ON then the system operates similar to summer mode ut solar pump activity is
monitored and will force a 3 minute flush if solar has not een active for seven days, note the unit may flush if
winter mode is selected on the day of install.
**Factory default for solar mode is SUMMER MODE
6) S STEM SETUP
4 options are availa le under system setup, SET SYSTEM CLOCK, FACTORY SETTINGS, INSTALLER SETUP,
TEMPERATURE LOG and EXIT.
EXIT - will return you to 6) SYSTEM SETUP with no changes.
SET SYSTEM CLOCK – allows you to adjust calendar and time of day.
FACTORY SETTINGS – restores ALL the settings to the factory default state.
TEMPERATURE LOG – Logs min/max temperatures & time, NO support is offered for this feature.
INSTALLER SETUP –
This su -menu is for installers ONLY, plum ing configuration, valve use, lock solar to filter pump, solar start and
end time, start and end temperature differentials can all e adjusted.
PLUMBING CONFIG: - Two options are availa le;
Independent – Solar pump has its own suction & return lines and operates without overriding the filtration pump,
when this plum ing configuration is selected you can then choose when the hour the solar pump is allowed to start
and the hour at which it is forced to stop, you can also choose to modify the differentials, the start differential is
the temperature rise the roof needs a ove the pool temperature to start the pump, the end differential stops the
pump when the roof drops elow the pool temperature plus the end differential.
Series Retro – this is where the solar pump is in series with the filtration pump, when this plum ing configuration
is selected you can then select if a solar divert valve is used instead of a solar pump, and wether to lock the solar
operation to the filter pump (locks to the filter timer and/or the AUX. HEATER timer) or if not you can choose the
start and end hour of the solar, you can then choose to modify the differentials (as descri ed for Independent
systems)
SETTING THE PLUMBING CONFIGURATION TO THE WRONG SETTINGS MA DAMAGE PUMPS AND/OR
PLUMBING!
**Factory default for installer setup is series retro-fit locked to filter, no valve, solar allowed to start at 09:00,
forced to end at 17:00, Start Differential of 8°C End differential of 4°C
7) SAVE & EXIT
When this menu is selected, push Enter to save ALL settings, the unit will return to normal automatic operation.
Note: If any of the menu items are left unattended for 3-4 mins the menu will time out and automatically save all
settings and return to operation.
The ENTER/MANUAL button (Manual heating mode)
FOR MANUAL MODE
PRESS ENTER NO
Pressing the Enter utton once will display the a ove message for ~3 seconds, to prevent accidental manual mode
if ENTER is not pressed again within the 3 second period then the controller will revert to automatic operation (and
it will cancel any pump lockout delays).
If ENTER is pressed again within 3 seconds then manual mode is activated, the solar pump is stopped (if
operating) and the aux pump (filtration) is switched on, the following is displayed;
MANUAL MODE 4HR
23.5° SET=30.0°
The displayed temperature on the left hand side is the water temperature; the SET temperature displayed on the
right hand side is what manual mode will heat the water to efore the aux. heater is switched off.
Use Up utton or Down utton to change the SET temperature to the required comfort level.
Press & hold ENTER/MANUAL to exit manual heating mode and revert ack to automatic mode.
Manual heating mode will automatically revert to automatic operation 4 hours after the last temperature
adjustment.
