Ease of installation, operation and serviceability
The GL -30 Differntial Temperature Control is designed to meet you needs for ease of installation, operation and serviceability. The GL -30 offers you advanced operating features to provide differential temperature control, storage high limit and recirculate freeze protection functions for solar energy systems.

GL-30 output is designed to directly operate a circulaor or fan for heat collection purposes when the controller is sensing and appropriate temperature differential. An LED output indicator is provided as an aid for troubleshooting or servicing the system.

Adjustable differential within a range of 80 to 240F. Offers versatility to tailor controls to a specific system design. Systems with long piping may require a higher turn-on differential temperature. Open loop systems with short piping runs may require a lower turn-on differential for optimum performance.

Storage high limit is field adjustable over a 100 to 230F range. Offers flexibility to protect most types of storage systems.

Recirculate freeze protection turns the GL -30 output “on” to circulate warmer storage water through the collector(s) when near freezing temperatures are reached at the collector sensor. LED recirculate freeze indicator provides instant output status of this condition.

Test switch forces the GL -30 output “on” or “off.”
