1.3 TIME CLOCK SETTINGS

TIME CLOCK AA 300 with LPHW only
The time clock is a quartz 24 hour clock with 100 hours battery reserve used to control the automatic operation on
the AA300 unit per 24 hour time cycles.
The time clock setting determines the OCCUPIED/UNOCCUPIED periods and is set to match the operators
requirements regarding opening and closing times for the pool and possible times where the pool is covered.
The two settings are OCCUPIED or day time, and UNOCCUPIED or night time (covered).
The most obvious action of this change is to lower the pool hall air temperature to a determined level to
conserve air heating energy. This lowering of temperature is allowable because of the quiescent, and ideally
covered, condition of the pool.
Pool water occupied
Pool water unoccupied
SETTING ACTUAL TIME
Turn the large clock hand clockwise until the correct time of day is set, ensuring that the correct half of the day is
chosen (24 hour clock).
