GL30 Goldline Solar Control
The Goldline GL-30 differential temperature control is designed for solar heating. The control output is typically wired to a cirulator pump or blower which is turned on when the collector sensor temperature is hotter than the storage tank sensor temperature. The control also provides an adjustable recirculate freeze protection.
Sensors can be located up to 1000 feet away.
