Autopilot Day & Night Heating / Cooling Thermostat APCET2 is a precision temperature grow room controller for cooling OR heating devices. Connected devices are turned on & off based on the selected day and night set points. Growers can choose to have different day and night temperature set points that are automatically detected by the built-in photocell. Lock your day & night temperature variance to keep your cultivars strong & maximize growth. The new Memory-lock feature locks the set points into memory for consistent performance, even if the knobs are accidently bumped.
