Plus the GL-235 incorporates unique, microprocesser based construction to ensure reliability and accurate performance. ____________________________________________________ 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, with either model 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 Goldline GL-235 LV and GL-235 LV/HV Individual Models: GL-235 LV Model The GL-235 LV 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 has the additional feature of being used with 12 or 24 volt valves. The Goldline/Jandy valve controls pool water circulation by the pool's filtration pump - either through the solar collectors, or bypassing the solar collectors. Specific Applications: Designed for both residential and light-duty commercial pools in the small to mid-size pool heating range when the GL-235 LV controller only needs a Goldline/Jandy Valve, or if a maintenance change-out or upgrade is required. 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.GL-235 LV/HV Model The GL-235 LV/HV is identical to the GL-235 LV except that in addition to operating either a 12 or 24 volt valve, the GL-235 LV/HV will also operate a separate pump that is dedicated to solar circulation only. The pump can be sized up to 1HP with 120VAC and 2HP with 240VAC. 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. 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. ____________________________________________________ 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 calibratedwith 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: Both models GL-235-LV and GL-235-LV/HV control 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. Both GL-235-LV and GL-235-LV/HV 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. ____________________________________________________ HELP » Contact Customer Support Toll-Free help line offering unit selection and sizing support Online e-mail technical and installation support ____________________________________________________ Goldline is clearly recognized as the world leader!
