Heliotrope Thermal Delta T  Solar Hot Water Controller
DTT-94 (with line cord and receptacle )  DLTA 000 000

The Delta-T controller is a differential temperature thermostat designed specifically to regulate the operation of a solar hot water system.

Its basic function is to monitor collector and storage temperatures and to automatically turn a circulation pump or blower on or off at the appropriate temperature differentials. The controller can also provide additional functions, such as system freeze protection by recirculation, storage tank high limit shut off, or positive off when the collector is below 80°F.

Control does not include power cord or sensors. Requires two 10,000 Ohm thermistor temperature sensors.



The corded version requires no wiring. Simply plug the unit into an outlet, and plug or pump into the unit. A hardwired version is also available.
