The default version A is: powered by AC220V, can"'"t work with AC110V It is a Konlen WIFI timing temperature controller, which can realize temperature monitoring and multi-period timing heating Or refrigeration control, high or low-temperature APP push alarm. The product is suitable for various commercial and industrial occasions,such as HVAC system, thermal water process, boiler, breeding, intelligent electromechanical equipment and other heating / cooling control systems. Main Features 1.Real-Time Supervision: Controller and App display real-time temperature at same time. 2. Start / stop heating or cooling equipment remotely via App. 3. Preset Hot or Cold working mode: can auto turn on / off equipment when it reaches to the preset temeprature value. 4. Set upper and Lower limit value of temperature alarm, real-time push alarm notification to users"'" smartphone. 5. Scheduled on / off, can timing-control equipments. 6. Can use button A and B to turn on / off equipment and set auto-start/stop temperature value manually, so the controller can still work via manual operation when WIFI is offline. NoteKonlen Temperature alarm notification to App is only available when network is online. A: WIFI configuration button B: Turn on/turn off button The manual switch B is only effective when the current temperature is between the preset start and stop value. CDisplay real time temperature D: Status LED 1, 2 : Working power input: AC220V (available range from 210V to 240V) 3, 4: Relay normal open output 5, 6: No use 7, 8: Connect with temperature sensor There is No distinction of positive and negative Preset Hot or Cold working mode: When the preset start temperature is higher than stop value, it is cooling mode. For example, xx 25 C, start the cooling equipment; xx 10C, stop it. When the preset start temperature is lower than stop value, it is heating mode. For example, xx 5C, start the heating equipment; xx 20C, stop it. Set upper and Lower limit value of temperature alarm For example : Set the temperature range ( 25~33 centigrade degree ) .when the temperature in house is within the temperature range , the controller will work normal . If the temperature is lower than 25 centigrade degree or higher than 33 centigrade degree , it will push alarm notification to users"'" smartphone via APP. Scheduled on / off, can timing-control equipments. Packing List: One temperature controller One temperature sensor with 2 meter cable. One English manual instruction. If you want the probe with longer cable, users can extend it to be about 20 meters Max.
