GL-235
Pool/Spa Heating Control Feature
Highlights:
Maximizes solar system performance by
dramatically
increasing system efficiency!!!
Microprocessor based ensures total digital
accuracy
Selectable high limit control
Automatically switches from heating to
nocturnal cooling
Re-circulation freeze protection [field
selectable]
Nocturnal cooling [field
selectable]
75°F to 104°F precision calibrated temperature
control
dial with "solar off" position
The
GL-235 automatically maximizes the heat collection of any
solar
pool heating system, being totally compatible with all new or
existing systems, new or existing pool/spa applications, and new or existing
12VAC or 24VAC actuator valves.
The pool/spa temperature level is
set by a single dial adjustment
with the desired temperature using a clearly
indicated dial. This dial is
highly calibrated for quick and easy,
user-friendly operation.
Plus, the GL-235 will automatically
determine if the water should be
solar heated or cooled, thus
maximizing your swimming comfort.
The GL-235 LV/HV unit
utilizes the existing pool's circulation pump for solar heat pick-up. It works
in conjunction with the Goldline/Jandy 3-Way 12VAC Valve and Actuator model
JVA-PKG, or with other manufacturer's 12VAC valves.
This
unit can operate either 12 or 24 volt valves. In addition, the GL-235
LV/HV will also operate a separate pump that is dedicated to solar
circulation only. The GL-235 LV/HV model has one low-voltage output for
controlling a single valve and a second high voltage
output for controlling a filter pump or solar booster
pump.
The pump can be sized up to 1HP with 120VAC and 2HP with 240VAC.
Specific Applications: Designed for both residential
and medium-duty
commercial pools in the small to
mid-size pool heating range when the
GL-235 LV/HV controller needs a
Goldline/Jandy Valve, plus operate a
separate pump that is dedicated to
solar circulation only.
Note: The unit has a front panel switch
which provides for nocturnal pool
cooling instead of heating. Cooling is
used in conjunction with the pool's
filtration pump being allowed to run
during the early dawn, cooler hours.
Installation Note: The GL-235 is
designed for outdoor use. For safety,
the GL-235 must be a minimum of 5 feet
horizontally from pool or
spa.

The
GL-235 Goldline Series Operational
Details:
Automatic
Heating
If the water within the collectors is warmer than the
pool water
by 4 degrees or more, and the pool is below the selected
desired
temperature, the valve will rotate allowing heat collection.
The heat collection will stop when the solar sensor output falls to
within 1.5 degrees of the pool temperature or the pool temperature
exeeds the "desired temperature" set on dial.
Automatic Nocturnal Cooling [Field
selectable option]
Swimming pools often become too warm from the sun on
their own
during the heigth of the summer season.
The
GL-235 comes standard with nocturnal cooling logic, which can
be
enabled/disabled via the main circuit board. During nighttime hours,
when
enabled, the GL-235 will circulate warmer water from the pool
to collector
panels, thus cooling the pool over time.
If the water within the
collectors is cooler than the pool water
by 6 degrees or more, and
the pool is above the selected desired
temperature, the valve will rotate
allowing cooling via the collectors.
The heat dissipation will stop when
the collectors sensor output rises
within 3 degrees of the pool
temperature, or the pool temperature
is lowered below the set desired
temperature.
Setting Desired Temperature
The GL-235 logic is set by a single dial adjustment with the
desired pool/spa temperatures clearly indicated. The dial is
calibrated
with the temperatures from 70 degrees to a high of 104
degrees for
quick and easy, user-friendly operation.
The
temperature set indicates set pool/spa temperature, and the
GL-235 will
automatically determine if the water should be solar heated
or cooled, thus
maximizing the system capabilities.
Terminal Connections
For input power, and sensor
inputs; controls also have industry
standard 3 pin connectors for both
forward and reverse valve actuator
operation and screw terminal connectors.
LED Digital Indicators
Show the status of the system
operation; four highly visible LEDs show:
1. Power
to the control
2. Power output directing valves
and/or pump to collect heat
3. Power
output directing valves and/or pump to dissipate heat
4. Sensor fault indicator shows sensor(s) not operating
properly
GL-235 Valve Electrical Ouput
Rating is the
industry standard 24VAC. A jumper switches the output
to 12VAC for
compatibility with older valve actuators.
Output is fuse
protected.
Freeze Protection [Field selectable
operation]
Turns the GL-235 recirculation output ON, directing warmer
pool/spa
water through the collectors when near freezing temperatures are
reached at the collector sensor.
The GL-235 will allow recirculation
when the collector temperature
rises to 42 degrees. Two 10K Ohm sensors are
required for operation.
One or more freeze snap switches are recommended
if freeze
recirculation protection is utilized.
Note: see installation instructions before using
Recirculation Freeze
System Test Switch
Allows the user to
manually override the automatic function of the
GL-235 and verify operation.
____________________________________________________
Installation
Technical/Operational Details:
The
GL-235-LV/HV controls a single valve. In most applications this is the
solar valve, which diverts water through the solar collector panels or through
the normal pool loop depending on conditions.
Units are shipped with the output voltage set to the
industry standard 24VAC.
For older systems
with 12VAC valves, an internal jumper can be moved to select 12 VAC output
operation.
The GL-235 provides two
different types of connections to the pool/spa actuators. When used with
newer actuators manufacturered by Goldline, Compool, Hayward, and Jandy that
come standard with wire end connectors, two 3-pin connectors are supplied. For
older actuators with no wire end connector, a 3 position terminal
block is supplied.
