Sensor Mounting and Wiring
Most installations use a Goldline "PC" type sensor for both the "SOLAR" sensor
and "POOL" sensors. The "AUX" sensor is required for optional recirculate
freeze protection (see description of this function on page 9). Otherwise, the
"AUX" sensor can simply display the ambient air temperature.
Any 10K ohm Goldline sensors may be used. Wire should be twisted pair 20AWG.
Sensor wiring run outdoors must be rated for outdoor use and ensure that the wire
connectors are protected from the weather. For long runs or runs near other electri-
cal wiring use shielded cable (Belden 8428 for outdoor use). Ground the shields to
the Aqua Solar's ground screw.
High Voltage Relay Output Wiring
A maximum of two high voltage relays (industry standard) may be added to the
AQ-SOL-LV. The AQ-SOL-LV-TC model comes with one relay for the filter pump
control already installed and one additional relay may be added. Order additional
relays separately (Goldline p/n "AQ-RELAY"). The relays are industry standard
and are double pole, single throw meaning that they can make/break both legs of a
240VAC circuit. Screw the relays into the mounting bracket and connect the coil
to the proper connector for these desired functions:
BOOST: This relay controls a booster pump for systems where the main filter
pump does not have enough power to pump water through the collector array. The
boost pump turns on 30 seconds after solar heating/cooling turns on.
AQ-SOL-LV: For most systems, simply connect the Aqua Solar power to the
LOAD side of the filter pump timer. If the Aqua Solar is connected to LINE power
(typically when "Recirculate Freeze" or "Solar Override" features are also being
used), then the input power to the boost pump relay should be connected to the
LOAD side of the filter pump timer. See wiring diagram on page 6 (bottom).
AQ-SOL-LV-TC: The Aqua Solar will automatically ensure that the filter pump is
running before turning on the boost pump. See wiring diagram on page 7.
SWEEP INTERLOCK: The relay is wired in series with the pool sweep and
turns the pool sweep off for approximately 6 minutes whenever the solar turns on.
This prevents the pool sweep pump from losing prime while air is being purged
from the solar collector array. For model, AQ-SOL-LV-TC the relay will also turn
the pool sweep off whenever the filter pump is turned off. See wiring diagrams on
page 6 (top) and on page 7 (bottom) for typical wiring.
FILTER PUMP: The function of this relay varies with the model of the Aqua
Solar. If the "Solar Override" is enabled (see "Jumper Settings"), the Aqua Solar
will override the time clock and turn the filter pump on when there is a call for
solar heating. If "Recirculate Freeze" protection is enabled, the Aqua Solar will
turn the pump and solar valve on during freezing conditions.
AQ-SOL-LV: This relay should be wired in parallel with the filter pump timeclock
contacts as shown on page 6. Be careful to make sure the phases do not get re-
versed.
AQ-SOL-LV-TC: This relay is the primary control for the filter pump—there is no
other timer. The Aqua Solar will operate the filter pump according to the "trippers"
set on the built-in timeclock in addition to the optional "Solar Override" and "Re-
circulate Freeze" options.
