About this item

• 3-IN-1 VERSATILE MODE — One device, infinite possibilities. The KT3500 Thermostat Outlet offers 3 selectable working modes: M1 TC mode for constant temperature control; M2 TC+Timer mode for day/night dual-temperature control; M3 Timer mode for 24-hour on/off timer control of lights, fans, or other devices. Ideal for reptile terrariums, seed germination, greenhouse and home brewing fermentation. 100-250V AC, Max 15A/120V output.
• M1 SIMPLE THERMOSTAT MODE — Just Set Two Temperatures – Choose a Start Temperature and Stop Temperature. The KT3500 thermostat plug outlet automatically decides whether to heat or cool: if Start Temperature > Stop Temperature, it cools; if Start Temperature < Stop Temperature, it heats. No complicated wiring, no confusion. Temperature control range: -40°F~248°F / -40°C~120°C, Control accuracy: ±2°F/±1°C.
• M2 DAY/NIGHT TEMPERATURE CONTROL MODE — Set separate start times and target temperatures for day and night cycles on a 24-hour schedule. The KT3500 temperature controller automatically switches between heating and cooling to create natural daily temperature swings. Ideal for reptiles, seed germination, or any setup where day/night variation supports health and growth. Range: -40°F~248°F (-40°C~120°C), Accuracy: ±2°F/±1°C, Timer: 0-24h daily cycle.
• M3 24-HOUR TIMER MODE — Pure On/Off Schedule – No temperature control, just simple timing. Set an ON time and an OFF time (e.g., ON at 8:00, OFF at 18:00). The connected device will turn on from 8:00 to 18:00, then stay off from 18:00 until the next 8:00, repeating this cycle every day. Perfect for lights, fans, pumps, or any equipment that just needs a daily schedule. Timer: 0-24h daily cycle.
• ACCURATE & RELIABLE — 3m Probe, Backlit LCD & Power-Off Memory – The KT3500 Plug-in thermostat with timer includes a 3-meter NTC 10K probe with manual calibration support. The large backlit LCD is easy to read in any lighting. All your temperature and timer settings are saved permanently — no need to reprogram after a power loss. Only the real-time clock needs to be reset if power is out for more than 2 weeks.
• DETACHABLE CONTROL PANEL WITH 9.5FT CABLE — The control panel separates from the power outlet, allowing you to mount the LCD display at eye level for easy viewing and adjustment, while the outlet and 3m (9.8ft) temperature probe remain hidden inside your terrarium, grow tent, or greenhouse. No more bending down or reaching behind furniture — perfect for tight spaces, refrigerators, or fermentation chambers.
