Thermoelectric Temperature Controller

Provides PWM regulation of cooling and heating output for TEC units. Automatically switches between cooling and heating. 4 cooling temperature set points range from 22.5 C to 35 C (35 C Factory Setting). 3 heating temperature set points range from -5 C to 15 C (15 C Factory Setting). Heating function can be easily disabled if desired. On-board LEDS indicate low temp, high temp alarm, and overall system status. Dry contact relay output provides for external alarm indication.
