AC 110-220V LED Digital Thermostat Hygrostat Temperature Humidity Controller for Aquarium Incubator Thermoregulator SHT20 Sensor Specification: Product Name: Temperature and Humidity Controller Product model: DTC3200 Power supply voltage: AC 110 -230V Power supply frequency: 50 / 60Hz Sensor Probe Length: 1m Sensor Probe Type: SHT20 Temperature measurement range: -20 -60 Humidity measurement range: 0% -100% RH Temperature measurement accuracy: 0.3 Humidity measurement accuracy: 3% Output control: Relay output Output power: MAX 10A Size: 93*56*34mm Setting: Setting method: start value stop value (the program automatically determines the working mode to be cooling / dehumidifying mode) Heating / cooling mode setting Setting method: setting (starting temperature): long pre the button, the starting temperature flashes, and the starting temperature value is set by the button Setting (stop temperature): long pre the button to stop the temperature flashing, set the stop temperature value by button Heating use case: control the water heater, heating to 65 to stop, the temperature drops to 50 to start heating again The first step: heating working mode, start temperature stop temperature Step 2: Pre and hold the button, the starting temperature flashes, and set the starting temperature to 30 via the button Step 3: Pre and hold the button to stop the temperature flashing, and set the stop temperature to 26 C with the button. The setting is complete! Humidification / dehumidification mode settings: Setting (Start Humidity): Long pre the key, the start humidity value flashes, and set the start humidity value with the key. Set [Stop Humidity]: Long pre the key, stop the humidity value flashing, and set the stop humidity with the key value. Examples of humidification: Fresh supermarket humidification, control humidifier 50% RH to start humidification, humidification to 80% RH to stop humidification. Setup steps: Step 1: Pre and hold the key for 3 seconds to start the humidity value flashing, and set the start humidity value to 50% RH. Step 2: Pre and hold the key for 3 seconds to stop the humidity value flashing, set the value to 80% RH, the setting is completed, pre the button for 5 seconds without operation, and automatically return to the normal display state Dehumidification example: workshop control exhaust dehumidification system, humidity 70% RH starts dehumidification, humidity 40% RH stops dehumidification Setup steps: Step 1: Pre and hold the key for 3 seconds to start the humidity value flashing, and set the start humidity value to 40% RH. Step 2: Pre and hold the key for 3 seconds to stop the humidity value from flashing, set the value to 70% RH, the setting is completed, pre the button for 5 seconds without operation, and automatically return to the normal display state Temperature correction: Simultaneously pre the key for 3 seconds to start the temperature digit flashing, and use the key to set the start temperature correction value; after the setting is completed, pre the button for 5 seconds without operation, and automatically return to the normal display state. Humidity correction: Simultaneously pre the key for 3 seconds to start the humidity digit flashing, and set the humidity correction value by the key; after the setting is completed, pre the button for 5 seconds without operation, and it will automatically return to the normal display state.
