Description of the control The GL-235 is designed to meet the need for easy installation, dependable operation, and serviceability. The GL-235 incorporates unique, microprocessor based construction to ensure reliability and accurate performance. The GL-235 offers advanced operating features to provide differential temperature control, selectable high limit, programmable recirculation freeze protection, nocturnal cooling and optional booster pump control. AUTOMATIC HEATING: If the collectors are warmer than the pool water by 4° or more, and the pool is below the selected desired temperature, the valve will rotate allowing heat collection. This heat collection will stop when the solar sensor falls to within 1.5°F of the pool temperature or the pool temperature exceeds the "desired temperature" set on dial. AUTOMATIC COOLING: (Field selectable option) If the collectors are cooler than the pool water by 6°F or more, and the pool is above the selected desired temperature, the valve will rotate allowing cooling via the solar collectors. The heat dissipation will stop when the collectors rise within 3 of of the pool temperature or the pool temperature is lowered below the set desired temperature. SINGLE SETTING FOR 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°F to a high of 104°F 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 STRIP 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 INDICATORS: Show the status of the system operation, Four highly visible LED's show 1) power to the control, 2) power output directing valves and/or pump to collect heat (heating), 3) power output directing valves and/or pump to dissipate heat (cooling), 4) sensor fault indicator shows sensor(s) not operating properly. GL-235 VALVE OUPUT: Rating is the industry standard 24 VAC. A jumper switches the output to 12VAC for compatibility with older valve actuators. Output is fuse protected. RECIRCULATION FREEZE PROTECTION: (field selectable operation) turns the GL-235 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°F. Two 10K Ohm sensors are required for operation. One or more freeze snap switches are recommended if freeze recirculation protection is utilized. Important--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.

Model GL-235-LV Control The model GL-235-LV has one output: 1) Selectable low voltage output for 12/24 VAC valve actuator. Wire via 3 pin connectors or terminal block (compatible with older actuators). Temperature Sensors All Goldline temperature sensors are 10K Thermostats which are accurate to +/- 1/2 F. The sensors are double-dip potted in silicone for maximum protection from moisture. PC: Multi-purpose sensor that can be used for both Solar (surface mount) or Pool/Water (drill-in plastic piping).

PENTAIR / COMPOOL LX2202TX POOL CONTROL COMBO
The LX2202TX Control System is a differential temperature control designed for solar-heated Swimming Pool applications. Whenever solar energy is available, the Control will automatically activate a motorized three-port Solar Valve and/or a Solar Booster Pump. 

HelioMatic - Model HM4000C
(For the Pool)
The HM4000C utilizes the existing pool's circulation pump for solar heat pick-up. The HM4000C has a front panel switch which provides for nocturnal pool cooling instead of heating. Cooling is used in conjuction with the pool's filtration pump being allowed to run during the early dawn, cooler hours. The HM4000C works in conjuction with the Flo-Verter 12VAC valve (or other manufacturer's 12VAC valve.) The valve allows circulation by the pool's filtration pump either through the solar collectors or not through the solar collectors. During nocturnal cooling the solar collectors serve as a source of a lower temperature than the pool water and thus reduce the pool's elecated temperature casused by excessively warm days. Fusing is accessed by removal of a barrier attached to the front panel. The HM4000C has the additional feature of being able to be used with either 12 or 24 volt valves.


HelioMatic - Model HM5000
(For the Spa)
The HM5000C is identical to the HM4000C except that in addition to operating either a 12 or 24 volt valve, the HM5000C 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.

A unique feature of the HM5000C is a built in time delay for pool sweep considerations. When the HM5000C calls for solar heat pick up, the valve will immediately activate. However, there is an approximate 8 minute delay before the pump turns on. This feature prevents pool sweep malfunction due to the introduction of air into its pumped line. This function can be disabled. When using a valve system only, the pool sweep pump may be wired to the HM5000C output (must be the same voltage as the pool filtration pump.) This method of pool sweep hook up will allow the pool sweep to operate only when the solar collection is taking place and the piping system will be purged of any air.

Flo-Verter
The Flo-Verter valve can be used with either of the Helio-Matic models. The Flo-Verter valce is a 12VAC, 2" valve. The Flo-Verter never needs lubrication, utilizes permanant magnet synchronous motors, has an extremely low CV factor due to the curved/directed flow channel inside the diverter, and may be mounted in any position except upside down.

One port is identified "FLOW TO COLLECTOR." An adequate length of three wire color coded cable is permanantly attached to the Flo-Verter valve and these three wires connect to the color identified terminatls at the Helio-Matic controller. There is never a need to check flow direction as an error is impossible if the same colors are connected together. The Flo-Verter is a non-positive seal valve and the diverter has a small hole, which allows the collector to drain when the system is off. This draining prevents collector damage due to freeze ups.

Sensors
The standard sensors are one AS-2-10 aluminum sensor for collector simulation and one IS-1.0 sensor which is clamp inserted into a drilled hole in 1 1/2" or 2" pipe. If a glazed collector is used, specify the SAS-10 sensor instead of the AS-2-10. Other substitute sensors are the BP-25-10 and BP-50-10 which are brass threaded 1/4" and 1/2" MBT.

Freeze Protection
 Freeze protection is accomplished in a valve controlled system by the collector draining back to the pool when the circulation pump is off. The air venting and vacuum relief valves allow air to enter the collectors at the highest point. On non-draining types of collectrs such as those mounted below pool level and on certain system designs where the collectors do not drain back to the pool, a different method of collector freeze protection must be provided. For these systems the FS-4 freeze sensors are available which, when wired with an HM5000 unit, will cause the pump to turn on at 42 degrees farenheit, thus preventing the collector from freezing. Helio-Matic and Flo-Verter valve are manufactured by Heliotrope Pool, and distributed by JED Engineering, Inc.
