5-Year Limited Solar Warranty
This Five Year Limited Warranty statement is only applicable to Solar controls and accessories sold and installed within the USA and Canada* and supersedes any warranty statements dated prior to November 1, 2010.
Hayward warrants its Hayward solar products to be free from defects in material or workmanship, under normal use and service for 5 years from date of manufacture, providing it is installed according to the installation instructions and specifications. The datecode stamped on the outside of the product and also coded on the printed circuit board will be the sole determination of manufacturing date.
To obtain warranty service or repair, please contact the place of purchase or the nearest Hayward authorized warranty service center. For more information, please contact the Hayward Technical Service Support Center or visit us on the web at www.haywardnet.com. Hayward will not assume any of the cost incurred in removal or reinstallation of the product. One year outside the USA and Canada.
The express warranty above constitutes the entire warranty of Hayward Pool Products with respect to its solar products and IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING A WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE. IN NO EVENT SHALL HAYWARD BE RESPONSIBLE OR ANY CONSEQUENTIAL OR INCIDENTAL DAMAGES OF ANY NATURE WHATSOEVER.
No wholesaler, agent, dealer, contractor, or other person is authorized to give any warranty on behalf of Hayward. This warranty is void if the product has been altered in any way after leaving
the factory.

Unless a copy of the original purchase invoice is enclosed, the manufacturing datecode on the product will be used to determine the repair charges. Hayward reserves the right to charge a nominal fee to cover inspection, test, and return freight for all controls where no faults or problems are detected. All charges will be COD (COD charge will be included) unless you already have an open account in good standing with Hayward. If the product returned can not be repaired, Hayward will offer and equivalent credit towards the purchase of any new Hayward product. Products that exhibit evidence of abuse, misuse, field damage (water/fire damage, line voltage applied to low voltage terminals, missing parts, etc.) or installed for more than the warranty period are not eligible for warranty repair replacement.

Description
TheGL-235isadifferentialtemperaturecontrolforsolarheatingofpools,spas,andhot tubs. It provides differential temperature control with an adjustable, calibrated water temperature high limit. Automatic nocturnal cooling (for pools that overheat in hot climates) and recirculate freeze protection functions can be enabled/disabled via internaljumpers.
Inputpowercanbeeither115or240VAC. Theoutputcontrolsa24VACautomaticvalve actuator. For older systems with 12VAC valves, an internal jumper can be moved to select 12VAC output operation. The GL-235 also has a high voltage output for controlling a filter pump or booster pump.

Installation
Mounting
The GL-235 is designed for outdoor use. Mount the box vertically with the knockouts facingdownward. Forsafety,theGL-235mustbeaminimumof5feet(horizontally)from the pool or spa.
Powerinput
Turn off power at circuit breaker before wiring. Remove the internal panel to expose thewiringconnections. Either115VACor240VACcanbeused. Refertotheinputwiring diagram(Figure1)onnextpage. WARNING: Applying240VACtothe120VACinput terminalswillcausepermanentdamagetothecontrol.
Grounding
RefertoNECandlocalcodesforspecificgroundingrequirements. Ingeneral,aseparate ground conductor must be run to the ground terminal on the pool service panel.
LowVoltage(LV)output: SolarValve
The GL-235 controls a single valve. In most applications this is the solar valve, which diverts water through the collector panels or through the normal pool loop depending on conditions.
All controls are shipped with the output voltage set to the industry standard 24VAC. To use the GL-235 with older 12VAC valves, move jumper J4, located on the right side of the circuit board.

With the sensor disconnected from the unit, measure the resistance of the sensor using an ohmmeter. At room temperature (25ºC/77ºF) the sensor should measure approximately 10K ohms (10,000 ohms ± 1%). For other resistance measurements at different temperatures, consult the table at back of manual. If the sensor is not returning the correct value, it is defective and will need to be replaced. If the sensor is returning approximately the correct value, reconnect it to the terminals marked “SOLAR SENSOR”. If the “CHECK SENSOR” indicator remains on, the unit is defective and needs to be replaced.
IfFREEZEPROTECTIONisenabled:
When a sensor is disconnected from the unit and freeze protection has been enabled, the GL-235 will recognize this as a freeze condition and activate freeze protection.
Temperature/Resistance/Voltage
AllHaywardcontrolsuse10Kthermistorsensors. Whendisconnectedfromthecontrol the sensor will read 10K ohms at 25ºC/77ºF. Refer to the chart below for the resistance at other temperatures. For a given temperature, the resistance reading should be accurate to ±1%. For a given resistance reading, the temperature reading should be accurate to ±0.5ºF. Voltage measurements should be accurate to ± 2%. Ohm measurements made with sensor disconnected from unit. Voltage measurements made with sensor connected to unit and power applied. Sensor voltages are DC volts.
