Figura 2: Dimensions of the NICREW Digital Temperature Controller and its probe cable length. The main unit measures approximately 13.5 cm in length and 5.5 cm in width. The power cord is 100 cm long, and the temperature probe cable is 85.5 cm long.
Configuració
- Col·locació: Choose a suitable location for the temperature controller. Ensure it is in a dry area, away from direct sunlight or extreme temperatures.
- Instal·lació de la sonda: Carefully place the temperature probe in the desired environment where temperature needs to be monitored and controlled. The probe is waterproof and can be situated in both wet (e.g., aquarium water) and dry (e.g., terrarium substrate) conditions.

Figura 3: The temperature probe can be placed in both wet environments like an aquarium and dry environments like a terrarium.
- Connect Heating/Cooling Device: Plug your heating or cooling device (e.g., heat mat, aquarium heater, cooling fan) into the power outlet on the temperature controller.
- Encès: Plug the temperature controller's power cord into a standard 220V electrical outlet. The LCD display will light up, showing the current temperature.
Instruccions de funcionament
Canvi entre Fahrenheit i Celsius
The unit can display temperature in either Celsius (°C) or Fahrenheit (°F). To switch between these units:
- Premeu el botó H / C button to toggle between heating and cooling modes.
- Manteniu premut el botó SET botó durant 3 segons per entrar al mode de configuració.
- Utilitza el UP or ABAIX arrows to select the desired temperature unit.
- Premeu SET de nou per confirmar i sortir.

Setting Temperature (Heating Mode Example)
To maintain a temperature range, for example, from 26°C to 29°C in heating mode:
- Choose the heating mode by pressing the H / C button until the "HEAT" indicator is lit.
- Manteniu premut el botó SET botó durant 3 segons per entrar al mode de configuració.
- Set the target temperature (e.g., 29°C) using the UP or ABAIX arrows. This is the temperature at which the heating equipment will turn off.
- Set the "DIFF" (differential) value (e.g., 3°C). This is the temperature difference below the target temperature at which the heating equipment will turn back on.
- En aquest example: 29°C (target) - 3°C (DIFF) = 26°C. Heating equipment turns on when temperature is < 26°C and turns off at 29°C.
- Premeu SET de nou per confirmar i sortir.
Setting Temperature (Cooling Mode Example)
To maintain a temperature range, for example, from 26°C to 29°C in cooling mode:
- Choose the cooling mode by pressing the H / C button until the "COOL" indicator is lit.
- Manteniu premut el botó SET botó durant 3 segons per entrar al mode de configuració.
- Set the target temperature (e.g., 26°C) using the UP or ABAIX arrows. This is the temperature at which the cooling equipment will turn off.
- Set the "DIFF" (differential) value (e.g., 3°C). This is the temperature difference above the target temperature at which the cooling equipment will turn back on.
- En aquest example: 26°C (target) + 3°C (DIFF) = 29°C. Cooling equipment turns on when temperature is > 29°C and turns off at 26°C.
- Set the desired delay value if applicable (consult specific device instructions for delay settings).
- Premeu SET de nou per confirmar i sortir.

Aplicacions
The NICREW Digital Temperature Controller is versatile and can be used in a wide range of applications requiring precise temperature control:
- Reptile Habitats/Terrariums: Maintain optimal temperatures for snakes, lizards, turtles, and other reptiles.
- Aquaris: Regulate water temperature for fish and aquatic plants.
- Incubators: Ensure stable temperatures for hatching eggs (e.g., chicken, reptile eggs).
- Hivernacles: Control ambient temperature for plant growth and seedling propagation.
- Fermentació: Provide consistent temperatures for brewing, making koji, or other fermentation projects.
- Pet Breeding: Create ideal thermal conditions for various small animals.

Figura 6: Examples of diverse applications for the temperature controller, including fermenters, terrariums, aquariums, incubators, pet breeding, greenhouses, plant seeding, and grow tents.

Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| La pantalla està apagada / Sense alimentació | Unit unplugged; Power outage; Faulty outlet. | Ensure the unit is securely plugged into a working outlet. Check household circuit breaker. |
| La lectura de la temperatura no és precisa | Probe not properly placed; Damaged probe; Environmental interference. | Reposition the probe. Inspect probe for damage; if damaged, replace the unit. Ensure probe is not near heat sources/sinks. |
| El dispositiu de calefacció/refrigeració no s'encén/apaga | Incorrect temperature settings; Device not plugged into controller; Device malfunction. | Verify target temperature and differential settings. Ensure device is correctly plugged into the controller. Test the heating/cooling device directly in a wall outlet. |
| "HHH" or "LLL" error on display | Temperature out of range; Probe disconnected or faulty. | Check if the temperature is outside the 16-40°C range. Ensure the probe is securely connected. If the problem persists, the probe may be faulty. |
