4. Advertències de seguretat
Please read and adhere to these safety warnings to prevent injury or damage to the device:
- Before using this unit, carefully inspect the plastic casinComproveu si hi ha signes de danys. No utilitzeu el dispositiu si sembla danyat.
- 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. Exceeding these limits can cause damage or fire.
- Do not operate this unit in environments containing explosive gases, excessive steam, or high dust concentrations.
- 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. Refer to qualified personnel for servicing.
5. Configuració
- Desembalar: Carefully remove the KT3200 thermostat and its accessories from the packaging.
- Inspeccionar: Check the device for any visible damage as per the safety warnings.
- Connecta el sensor: Plug the 3-meter temperature sensor into the designated port on the thermostat.
- Encès: Insert the KT3200 into a suitable power outlet matching your regional plug type (e.g., EU, UK, FR, AU, US). Ensure the connected appliance's power requirements do not exceed the thermostat's output limits.
- Initial Clock Setting (M2/M3 Modes): If you plan to use M2 (Temperature Control + Timer) or M3 (Timer Only) modes, you will need to set the current time after powering on, especially after a power outage.





6. Modes de funcionament
The KT3200 offers three distinct working modes, selectable by pressing the 'M' button:

6.1. M1 TC: Temperature Control Mode
In this mode, the thermostat controls the connected device based on a single set of start and stop temperatures.
- Configuració: Set your desired start and stop temperatures using the '+' and '-' buttons, then confirm with 'OK'.
- Mode de calefacció: To operate in heating mode, set the start temperature to be menys que the stop temperature. The device will turn on when the measured temperature drops below the start temperature and turn off when it reaches the stop temperature.
- Mode de refrigeració: To operate in cooling mode, set the start temperature to be més gran que the stop temperature. The device will turn on when the measured temperature rises above the start temperature and turn off when it drops to the stop temperature.
6.2. M2 TC+Timer: Day/Night Temperature Control
This mode allows for two different temperature control programs (TC1 and TC2) to run during specified day and night periods within a 24-hour cycle.
- Configuració: Set the current clock time, then define Time1 (start of day period) and Time2 (start of night period). Also, set the start and stop temperatures for TC1 (Day program) and TC2 (Night program).
- Funcionament: During the Daytime (from Time1 to Time2), the device will run the TC1 program. During the Night time (from Time2 to Time1), it will run the TC2 program.

6.3. M3 Timer: 2 Timer Period Timer Only
This mode functions purely as a timer, turning the connected device on and off at specified times.
- Configuració: Set the current clock time, then define Time1 (ON time) and Time2 (OFF time).
- Funcionament: The output will be ON from Time1 to Time2. The output will be OFF from Time2 to Time1.
7. Funció de memòria
- All configured data, except for the current clock time, will be saved automatically after a power failure.
- The clock time will need to be reset manually when the device is powered on again after an outage.
- If the KT3200 was operating in M1 mode before a power failure, it will automatically resume operation in M1 mode with its saved temperature settings once power is restored.
- If the KT3200 was operating in M2 or M3 mode before a power failure, you will need to reset the clock time first upon power restoration for these modes to function correctly.
8. Consells d'usuari
- Configuració de temperatura flexible: The KT3200 allows for a wide range of temperature settings, including scenarios where the turn-on temperature is higher than the turn-off temperature (for cooling) or vice-versa (for heating). For example, you can set it to turn on at 50°C and turn off at 30°C.
- Room Heating: This thermostat is well-suited for controlling room heaters to maintain a desired ambient temperature by automatically switching the heater on and off.
- Capacitat de càrrega: Be mindful of the maximum load. For EU/UK/FR/AU plugs, the maximum is 16A/230V (resistance load < 14A, inductive load < 2A). For US plugs, it's 15A/120V (resistance load < 14A, inductive load < 2A). Ensure your appliance's wattage is within these limits.
- Lectures estables: The temperature sensor is designed to provide stable readings, minimizing temperature fluctuations during operation.
9. Solució De Problemes
- Unstable Temperature Readings: If the displayed temperature fluctuates erratically, first check the connection of the temperature sensor. Ensure it is securely plugged in and that the sensor probe itself is not damaged.
- El dispositiu no s'encén/s'apaga: Verify that the start and stop temperatures are correctly set for your desired heating or cooling mode (M1). In M2/M3 modes, ensure the clock is set correctly and the timer periods are configured as intended. Check if the connected appliance is functioning correctly.
- No Output After Power Outage (M2/M3 Modes): If the device was in M2 or M3 mode and experienced a power outage, the clock needs to be reset. Reset the clock, and the device should resume its programmed operation.
- Protecció de sobrecàrrega: If the device unexpectedly shuts off, check the load connected to it. Ensure it does not exceed the maximum amperage for resistance (14A) or inductive (2A) loads.
