6. Configuració inicial

1. Desempaquetar el dispositiu: Carefully remove the KT3200 thermostat and its accessories from the packaging. Inspect the plastic shell for any signs of damage. Do not use the device if it appears damaged.
2. Connecteu el sensor: Plug the 3-meter temperature sensor into the designated port on the thermostat.
3. Connecteu-vos a la presa de corrent: Insert the KT3200 into a suitable power outlet (100~250VAC 50/60Hz).
4. Encesa inicial: The device display will light up. If operating in M2 or M3 mode, you will need to set the real-time clock.
5. Sensor de posició: Position the temperature sensor in the area where you wish to measure and control the temperature. Ensure it is not directly exposed to heat sources or drafts that could skew readings.

7. Modes de funcionament

The KT3200 offers three distinct working modes: M1 (Temperature Control), M2 (Temperature Control + Timer), and M3 (Timer Only).

Imatge: Més deview of M1 and M3 operating modes.

7.1 M1: Temperature Control Mode

In M1 mode, the device controls the output based on a set start and stop temperature.

• Configuració: Use the '+' and '-' buttons to adjust the 'Start Temperature' and 'Stop Temperature'. Press 'OK' to confirm.
• Mode de calefacció: Set the 'Start Temperature' to be lower than the 'Stop Temperature'. The output will turn ON when the measured temperature falls below the start temperature and turn OFF when it reaches the stop temperature.
• Mode de refrigeració: Set the 'Start Temperature' to be higher than the 'Stop Temperature'. The output will turn ON when the measured temperature rises above the start temperature and turn OFF when it falls to the stop temperature.

7.2 M2: Day/Night Temperature Control Mode

M2 mode allows for different temperature control programs during daytime and nighttime within a 24-hour cycle.

Image: M2 Day/Night Temperature Control Mode cycle example.

1. Estableix el rellotge: First, set the current real-time clock.
2. Set Time1 and Time2: Define the start time for daytime (Time1) and the start time for nighttime (Time2).
3. Set TC1: Program the temperature control settings (start and stop temperatures) for the daytime period (Time1 to Time2).
4. Set TC2: Program the temperature control settings (start and stop temperatures) for the nighttime period (Time2 to Time1).

The device will automatically switch between TC1 and TC2 programs based on the set times.

7.3 M3: Timer Only Mode

M3 mode functions purely as a timer, turning the output ON and OFF at specified times.

1. Estableix el rellotge: First, set the current real-time clock.
2. Set Time1 and Time2: Define the start time for the output to turn ON (Time1) and the start time for the output to turn OFF (Time2).

• Output ON: The output will be active during the period from Time1 to Time2.
• Output OFF: The output will be inactive during the period from Time2 to Time1.

8. Consells d'usuari

• Power Failure and Clock: After a power failure, all settings except the real-time clock are saved. For M2 and M3 modes, you must reset the clock upon power restoration for proper operation. M1 mode will automatically resume.
• Capacitat de càrrega: The relay has a maximum capacity of 16A. For resistance loads, ensure the connected appliance draws less than 14A. For inductive loads, ensure it draws less than 2A to prevent damage.
• Col·locació del sensor: The temperature sensor has a diameter of 5mm and a length of 25mm, made of stainless steel. It is suitable for use in liquid environments, such as a rectifying column, but ensure proper sealing and protection.
• Precisió de la temperatura: The device has a control accuracy of ±1℃/±1℉. Keep this in mind for applications requiring very precise temperature regulation.

9. Solució De Problemes

• El dispositiu no s'encén: Check the power supply and ensure the device is securely plugged into a working outlet.
• Incorrect Time/Schedule in M2/M3: If the device was powered off, the real-time clock needs to be reset. Navigate to the clock setting and adjust it to the current time.
• Output Not Activating/Deactivating:
  • Verify the working mode (M1, M2, M3) is correctly selected.
  • Check the set start and stop temperatures/times.
  • Ensure the connected appliance is within the specified load limits (resistance load < 14A, inductive load < 2A).
  • Inspect the temperature sensor for proper connection and placement.
• Lectures de temperatura inexactes:
• Ensure the sensor is not damaged or corroded.
• Check for external factors affecting the sensor, such as direct sunlight, drafts, or proximity to heat sources.
• Use the temperature calibration function if a consistent offset is observed.

10. Manteniment

• Neteja: Netegeu el dispositiu amb un drap suau i sec. No utilitzeu productes de neteja abrasius ni dissolvents.
• Inspecció: Regularly check the plastic casing for any cracks or damage. Do not use the device if it is damaged.
• Cura del sensor: Keep the temperature sensor clean and free from debris. If used in liquids, ensure it is properly sealed and cleaned after use to prevent corrosion.

11. Advertències de seguretat

• Before use, always inspect the plastic shell of the unit. Do not use if there is any damage.
• The relay has a maximum capacity of 16A. Please ensure that resistance loads are less than 14A and inductive loads are less than 2A to prevent overload and potential hazards.
• Do not use this unit in environments containing explosive gases, excessive steam, or heavy dust.
• Keep the device out of reach of children and do not allow them to operate it.
• Do not attempt to disassemble or repair the device yourself. Unauthorized modifications can lead to electric shock, fire, or device malfunction.

13. Preguntes freqüents (FAQ)

Q: Can I connect multiple temperature sensors to this device?

A: No, the KT3200 is designed to work with a single temperature sensor input.

Q: What are the dimensions of the temperature sensor, and can it be used in liquids?

A: The temperature sensor has a diameter of 5mm and a length of 25mm. It is made of stainless steel and can be used in liquid environments.

Q: Are settings saved if the power goes out?

A: Yes, all programmed data except the real-time clock is saved after a power failure. However, if you are using M2 (Day/Night Temperature Control) or M3 (Timer Only) modes, you will need to reset the clock manually upon power restoration for the timing functions to operate correctly.

Q: Can this device handle a 3kW heater?

A: The relay has a maximum capacity of 16A. For resistance loads, it is recommended to use appliances drawing less than 14A. For inductive loads, use appliances drawing less than 2A. A 3kW heater at 230V would draw approximately 13A (3000W / 230V), which is within the resistance load limit. However, always verify the actual current draw and type of load (resistance vs. inductive) of your appliance.
