SUMMER MODE
SUMMER MODE is the normal operation of heating the swimming pool.
WINTER MODE, when selected you will be prompted to select the start month of winter and the start month of
summer, the purpose of winter mode is not to use solar to heat the pool but to ensure the solar collector on the roof
gets flushed otherwise the water in the collector becomes contaminated. If AUX. HEATER is set to OFF 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.
If AUX. HEATER is set to ON then the system operates similar to summer mode but solar pump activity is monitored
and will force a 3 minute flush if solar has not been 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
