WILLHI Digital Temperature Controller Build in Outlet 1650W 110V 15A Over Current Protection Thermostat Controller Heating Cooling -58~230? for Reptile Freezer Greenhouse Temperature Control WH-1803A

This is the latest upgraded smart controller from WILLHI brand, the model is ?WH-1803A? you don't have to choose HEAT or COOL model for different device.What you need to set is only the ON temperature and OFF temperature. Example? if you need a constant temperature like 100F by a heater, you just need to set the ON temperature at 99F and OFF temperature at 100F. So your heating deceive will turn on at 99F and turn off at 100F automatically. But if you need a constant temperature like 70F by a cooler, then you can set the ON temperature at 71F and set the OFF temperature at 70F, so your cooling device will turn on at 71F and turn off at 70F automatically. Note:The WH-1803A can accurately control trun-on and off points. However, there might be overshooting due to wasted heat (thermal lag). It's not the WH-1803A's fault, you can consider changing the power of your heater to compensate the overshooting effect. Main Functions: it has very safe overcurrent breaker designing, it can shut off the heater or cooler automatically if the equipment got short circuit. Turn your device ON and OFF at desired temperatures. Settings are stored even when powered off.
