Specification: Power supply: 100~250V AC 50/60HzTemperature control range: -40℃~120℃/-40℉~248℉Setting time: 0~24h/daily cycle timerControl accuracy: ±2℉/±1℃Sensor: NTC 10K/B3950Output: Max 15A/120V (The relay is max 15A. Please use resistance load less than 15A, inductive load less than 2A.) M1 TC mode -- Temperature control mode Set start temperature and stop temperature, this thermostat plug outlet will work in heating or cooling mode as programmed. For example, set start temperature=20℃, stop temeprature=25℃, the heater will start heating when temperature < 20℃ and stop heating when temperature ≥ 25℃, when the temperature drops below 20℃, the heater will start to work again. M2 TC+Timer--Temperature + timer mode In this mode, you can set two different temperature settings with two time periods set during 24 hours. Time 1 ~Time 2 ~ Time 1 is a cycle, 24 hours. For example, set Time 1=8:00, Start Temperature TC 1=25℃, Stop Temperature TC 1=28℃; Time 2=18:00, Start Temperature TC 2 =28℃, Stop Temperature TC 2 =32℃. From 8:00 to 18:00, the heater will start heating when temperature<25℃ and stop heating when temperature≥ 28℃, when temperature drops below 25℃ again, the heater will start to work again; From 18:00 to 8:00 the next morning, the heater will start heating when temperature <28℃ and stop heating when temperature≥ 32℃, when temperature drops below 28℃ again, the heater will start to work again. M3 Timer mode--Day and night timer With ON/OFF time setting per day, you can program your devices to turn on/off regularly. For example, set Time 1 ON=8:00, Time 2 OFF=18:00, the device will be turned on from 8:00 to 18:00 and turned off from 18:00 to 8:00, then repeat every 24 hours.
