SELECT to accept. Next you will be prompted to set the differential hysteresis (END° x) which turns the
pump off when roof temperature is less than the pipe 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.
Next is anti-freeze
(this function is applicable to Aqua-Gen 3 & Aqua-Gen 3BR models only)
, you will be
prompted by FRZ? ON/OFF, adjust with the UP/DOWN button, press SELECT to accept. If you select OFF
then all the above settings will be saved and the unit will restart. If you selected ON then you will be
prompted to adjust the anti-freeze start temperature point as follows; FREEZ° x adjust with the UP/DOWN
button, press SELECT to accept.
Once the roof temperature gets to the anti-freeze setting or below then the pump will be turned on for 3
minutes then turn off for 30 minutes, this sequence will repeat until the roof temperature rises above the
anti-freeze temperature.
Factory Test
To run the factory test, hold the SELECT button when first applying power, the unit will perform a series
of self-diagnostic functions with the pump running. If there are any faults they will be reported on the
display before the unit restarts into normal operation.
Note: this will force all settings to a factory default state, if anti-freeze had been selected then turn it back on as
described under ‘adjustable differential and anti-freeze feature’. Also re-enable time-clock if desired.
Notes
1.
If a sensor fault is detected the controller will display which sensor failed (POOL and/or ROOF) and the
type
of
failure.
2.
Should power be interrupted for any reason, the controller will resume normal operation when
power is restored, all information will have been kept for up to 14 days.
3.
Temperature sensor used with this unit is digital and is accurate to 0.5°C, no calibration is required.
4.
The sensor cable with the thin trace is the positive and is usually fitted to the right hand side of the
green plug when looking at the plug screws, incorrect polarity will be displayed as a short circuit or
reversed fault.
5.
If the controller has stopped pumping and is displaying a higher temperature than expected it may
be caused by a pump which is failing to prime, check the pump and if necessary prime the pump as
per the pump manufacturers’ instructions then reset the controller by turning it off/on.
6.
Maximum rated output load for the 240V socket is 10 Amps 2400 Watt.
