1) MANUAL MODE
MANUAL PUMP MODE
UP=ON DOWN=OFF
MANUAL MODE allows you to manually set the solar pump to ‘on’ by pressing the
Up
button or ‘off’ by pressing the
Down
button. In manual mode the heater is switched off.
Pressing
Enter
will return you to the SETTINGS MENU. You can also keep pressing
Enter
to toggle the pump from ‘on’
to ‘off’ and vice versa.
MANUAL MODE will timeout, after 24 hours the unit will return to automatic operation.
2) TEMPERATURE
TEMPERATURE
SOL LIMIT XX.X°
When you enter the TEMPERATURE menu you may change the desired temperature of the pool for solar heating.
Change the desired temperature limit by pressing the
Up or Down
buttons, if no change is required simply push
Enter.
Heating will stop and sample waiting begins once the desired temperature limit is reached.
Note that solar heating can only occur if solar gain is available. (
SOLAR GAIN = YES
)
If the AUX. HEATER is set to ON then the following will also be displayed;
TEMPERATURE
AUX LIMIT XX.X°
You may change the desired temperature of the pool for auxiliary heating (in pool mode).
Change the desired temperature limit by pressing the
Up or Down
buttons, if no change is required simply push
Enter.
Heating will stop once the desired temperature limit is reached.
For maximum efficiency it is advisable that the solar limit (SOL LIMIT) be set slightly higher than the auxiliary limit.
**Factory default for AUX LIMIT is 27°C and SOL LIMIT is 30°C.
3) AUX. HEATER
AUX. HEATER
ON/OFF
When you enter the AUX. HEATER menu you will need to select ON or OFF, the selected option will be flashing, you can
use
Up/Down
to change the selected option,
Enter
to accept. This controls when the Aux Heater is allowed to operate.
If OFF is selected you will return to the menu, If ON is selected you will be prompted for START and END time, modify
values by using the
Up/Down
buttons, use
Enter
to accept the values.
HEAT DEMAND TIME
HEAT DEMAND TIME
START TIME X:XX
END TIME X:XX
If a 24 hour run time is required then set the start and end time to the same value. (e.g. Start 12:00, End 12:00)
Note 1: when SOLAR GAIN =HIGH is shown then the heater will stop as priority is given to low cost solar heating.
Note 2: High solar gain is defined as 15°C above the SOL LIMIT setting.
**Factory default for HEAT DEMAND is ON (06:00 to 22:00)
4) MODE
MODE
SUMMER MODE/WINTER MODE/TROPICAL MODE
You can use
Up/Down
to change the selected option,
Enter
to accept.
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 solar temperature limit is achieved; note that this is most likely to occur at night.
WINTER MODE, when selected you will be prompted to select the start month and end month of winter (inclusive, also
note that the start Month must be of lower value then the end Month.), this assists in the systems off-season
maintenance and save energy as solar gain may be available but swimming temperature cannot be achieved. Every day
a 3 minute flush of the solar matting occurs between 10:00 and 16:00 providing the roof temperature is equal or
greater than the pool, but if that condition does not occur a solar system flush will be forced to occur at 16:00.
**Factory default for MODE is SUMMER
