GL-30 Electronic Controls Differential Temperature Control

1 GL-30GL-30GL-30GL-30GL-30 Electronic ControlsDescriptionDescriptionDescriptio nDescriptionDescriptionThe Goldline GL-30 Differential Temperature Controls is designed to provide maximum operating efficiency and flexibility to effectivelymanage today's innovative solar energy systems. It is a continuation of the advanced Electronic technology which produced the popularC-30 and CM-30 controllers - standards of the solar industry since 1975, with hundreds of thousands of units installed worldwide. Withan adjustable high limit of 50 -104 F, the GL-30 is capable of handling most Differential Temperature Control functions for operation ofdomestic water heating and sophisticated space heating and cooling. The GL-30 is designed to Control recirculation, drain-back and closedloop Temperature ControlDifferential Temperature ControlDifferential Temperature ControlDifferential Temperature ControlDifferential Temperature ControlFast, easy installation -Fast, easy installation -Fast, easy installation -Fast, easy installation -Fast.

Solarsystems with long pipe runs normally require a higher turn-on diffeentialtemperature, and open loop systems with short pipe runs usually require alower turn-on differenttial Temperature for optimum performance. The GL-30offers versatility to tailor Controls to numerous specific systems High LimitThe GL-30 allows you to set a high limit storage Temperature from 110 to 230 Freeze ProtectionRecirculation freeze protection, when enabled, turns the GL-30 output on tocirculate warmer storage water through the collectors when near freezingtemperatures are reached at the collector Test SwitchThe system test switch manually switches the GL-30 to ON, AUTO, or OFF forcomplete Control over the system at all TD-GL Digital MonitorThe GL-30 contains a quick plug-in adaptor for easy connection to aGoldline TD-GL snap-in digital monitor.

5 This combination providesa digital readout of 1 F Temperature accuracy for maximizing operatingefficiency. The TD-GL also has a minimum/maximum memory fortemperatures seen at the collector sensor. The TD-GL may be snappedinto the cover of the GL-30 series Control or mount GL-30 may be connected in permanent installations or carriedaround as a convenient diagnostic tool.
