Description of Operation
Alternate Wiring Diagram (C)
POOLÕS ORIGINAL WIRING
This pool was equipped with a 220 vac pump that was connected to a timer.
Both sets of timer contacts were wired to run the pump. The customer purchased a
ÒMANUAL SYSTEMÓ and desired to use the timer to control both the pump and
the PCS1.
WIRING THE PCS1
Wire 220 vac from the timer to the PCS1. Wiring the PCS1 in this alternate
diagram C requires the use of one set of the timerÕs power contacts. The other set is
used for the poolÕs pump.
NOTE : Some pool pumps are 110 vac. In such a case, 220 vac must be ran to
the timer for use by the PCS1 [via the second set of power contacts].
SEMI-AUTOMATIC OPERATION
Both the pump and the PCS1 operate off of the same timer. The timer is set
to operate from 11 a.m. until 7 p.m. on sunny days. This covers part of the time that
the solar collection process occurs. In a fully automated system, the solar collection
process could start earlier and run later if heat is available.
SECOND TIMER
Another approach to using timers for low cost semi-automatic operation is to
simply use a different [second] timer for the PCS1. Make sure that both timers are
synchronized or the solar collection process will be degraded.
CAUTION NOTE:
The PCS1 will cool down the pool if the attic is colder than the pool water!
