SensorMountingand 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(seedescriptionofthisfunctiononpage9). 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 electrical
wiring use shielded cable (Belden 8428 for outdoor use). Ground the shields to the
Aqua Solar's ground screw.
HighVoltage RelayOutput Wiring
Amaximum of two high voltage relays (industry standard) may be added to the AQ-
SOL-LV. TheAQ-SOL-LV-TC model comeswith onerelayfor 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 theAqua Solar power to the LOAD
side of the filter pump timer. If theAqua 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.
SWEEPINTERLOCK: Therelayiswiredinserieswiththepoolsweepandturnsthe
pool sweep off for approximately 6 minutes whenever the solar turns on. This pre-
vents 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 8 for typical wiring.
FILTER PUMP: The function of this relay varies with the model of theAqua Solar. If
the "Solar Override" is enabled (see "Jumper Settings"), theAqua Solar will override
the time clock and turn the filter pump on when there is a call for solar heating. If
"RecirculateFreeze" protection is enabled, theAqua Solar will turnthe pumpand 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 reversed.
AQ-SOL-LV-TC: Thisrelayisthe 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 "Recirculate
Freeze" options. 5
