MODE OF OPERATION

Pressing the SELECT button once will display

the current mode of operation, pressing it

again or holding it will select the next

available mode of operation.

The available modes are SUMMER, MANUAL,

TROPICAL or WINTER.

Summer mode

is the normal operating mode

for heating the pool.

Winter mode

of operation is for off-season

maintenance or if pool heating is not required

(AWAY MODE)

. This is a better option than

turning off the controller as it will flush

treated pool water through the solar system

as well as prolong pump bearing and

mechanical seal life. The pump will run for 3

minutes each day from when the winter mode

was selected or at 10am if the time-clock

mode was selected.

Tropical

Tropical mode

mode

Tropical

mode

is for situations where the

pool

water

overheats

temperature limit due to direct heating from

the sun. The unit will attempt to sample the

pool water when solar gain is available and if

after 3 minutes the pool is above the desired

temperature limit then the controller will wait

until the roof is 4°C cooler than the pool

temperature, the pump is then started to cool

the pool (this will most likely occur at night).

Manual mode e e e

Manual mod

is for testing the pump

installation on a cold or cloudy day. Once

manual mode is selected the pump will start

if it has been off, or stop if it has been on

(running). After 30 minutes manual mode will

time-out and return to Summer Mode with a

default temperature limit of 30°C

Settings mode

is for setting the unit into

time-clock operation.

When you select this option you will be asked

if you wish to use the clock feature (CLK?

ON/OFF).

If you select OFF then the controller will not

work as a time-clock model and will prevent

beyond

the

set

starting the pump to sample at night based

on a sequence of events.

If you select ON you will be prompted to set

the time of day, the controller will work in

time-clock mode and the solar pump is

prevented from starting outside of the set

hours (unless tropical mode is selected). Set

the time of day in 24 hour format, note there

is an AM/PM indication to avoid incorrect

settings. Seconds are automatically set to

zero.

Once the time is set select the START hour

from 6am till 12 noon, default is 9am which

means the solar pump cannot start before

9am.

Now select the END hour from 15:00 (3pm)

until 21:00 (9pm), default is 19:00 (7pm)

which means the solar pump will stop at 7pm.

DIFFERENTIAL

FEATURES:

Special note: Adjusting these values to any

setting other than the defaults may adversely

affect the performance of this controller. To

select these features, hold the DOWN button

then press SELECT. When you select this

option you will be prompted to set the solar

gain start temperature (RUN° x) this setting

allows the pump to start if the roof

temperature exceeds the last valid pool

temperature or pipe temperature by this

value, adjust with the UP/DOWN button, press

SELECT to accept. Next you will be prompted

to set the differential hysteresis (END° x)

which turns the pump off when roof

temperature

temperature plus this value, adjust with the

UP/DOWN button, press SELECT to accept.

Default values are 8° for RUN and 4° for END,

these are the optimal values for maximum

efficiency, some coastal locations may

benefit from a reduced run value of 6°C for

RUN and 4°C for END.

The next item is anti-freeze, you will be

prompted by FRZ? ON/OFF, adjust with the
