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.
WILLHI Digital Temperature Controller has high quality UL Certification power cable, the top quality copper wire can load large currents.
Temperature calibration correction.
High and low temperature alarm.
Built in time delay feature to protect out device from excessive ON/OFF toggling.
Auto shut off time (disabled by default)

- 【Large Test Range of Temperature Controller】- High quality temperature controller comes from high quality probes, our temperature probe was made of NTC sensor with waterproof. Range: -50 ~110℃/ -58~230℉, Resolution: 0.1℃/ 0.1℉. Support heating and cooling model.
- 【Overcurrent Protection- Safety】- @110V 15A 1650W output apply to most household and industrial, 14 AWG UL certification input cable, it's thicker than most products on the market, But what's more worth mentioning is the over current protection feature: with over current breaker designing, it can shut off if short circuit or over current happened.
- 【Timing Delay and Alarm】- You can set 0-30 minutes shut off timing delay after temperature over or below your seted, this way the thermostat will not be turned off and on excessively. Set the maximum desired temperature for the heat mat. Alarm when temperature exceeds the limit or when sensor error.
- 【Widely Applied】- The thermostat can be used to control a wide variety of refrigeration and heating, seedling heat mat，pet breeding，incubation，HVAC equipment, accelerating germination，electric radiator, electric oven，fermentation, grow tent, home brewing, aquarium, Smoker and BBQ, etc.
- 【Service and warranty】- User friendly to setup tempereture controller with professional uesr guide. We provide this WILLHI Digital Temperature Controller with 6-Month Warranty and 24hours customer service.
