230V Energy Saving Easy-operated Heating Element Programmable Room Thermostat
ST2303 takes a different approach to scheduling: instead of a handful of temperature steps, it offers 48 time slots with two temperatures per day. That gives half hour resolution across the whole day between a comfort and a setback level, which suits heating elements and systems that respond quickly. It runs 7 day, 5/2 day and 24 hour modes with keypad lockout and manual override.
