DTT-84

Differential Temperature Controller

Uses two 10K sensors to perform all temperature sensing functions. Its basic function is to monitor collector and storage temperatures, and to operate a circulating pump or blower at the appropriate temperature differential. Can also provide freeze protection by recirculation, storage tank high limit and positive off when the collector temperature is below 80°F. Hard-wire power source required. Field selectable differential 18°/5° or 9°/4°. 10 amp rated relay. UL listed.
