4. Setup
- Unpack the Device: Carefully remove the temperature controller and its accessories from the packaging.
- Connect the Sensor: Insert the NTC 10K temperature sensor probe into the designated port on the controller. Ensure it is securely connected.
- Position the Sensor: Place the sensor probe in the environment where temperature needs to be measured and controlled. Ensure it is not directly exposed to heat sources or drafts that could affect its accuracy.
- Plug in the Controller: Insert the KETOTEK KT3200PRO into a standard power outlet (100-250Vac, 50/60Hz).
- Connect Heating/Cooling Device: Plug your heating or cooling appliance (e.g., heater, fan, lamp) into the outlet on the front of the temperature controller. Ensure the appliance's power consumption does not exceed the controller's maximum output (16A/230V).
5. Operating Instructions
The KT3200PRO offers three distinct operating modes: M1 (Temperature Control), M2 (Timer with Temperature Control), and M3 (Timer Only). Use the 'M' button to cycle through these modes.
5.1 General Controls
- M Button: Press to switch between operating modes (M1, M2, M3).
- OK Button: Confirm settings or enter setting mode.
- '+' Button: Increase values or switch between °C/°F (in certain contexts).
- '-' Button: Decrease values.
- Return/Reset Button: Go back to the previous screen or perform a reset.
5.2 Mode M1: Temperature Control
In M1 mode, the controller maintains a set temperature range by activating or deactivating the connected appliance. This mode supports both heating and cooling functions.
- Press 'M' until 'M1 TC' is displayed.
- Press 'OK' to enter setting mode.
- Set the 'Start Temperature' using '+' and '-' buttons, then press 'OK'.
- Set the 'Stop Temperature' using '+' and '-' buttons, then press 'OK'.
- The device will automatically operate in heating mode if 'Start Temperature' < 'Stop Temperature', or cooling mode if 'Start Temperature' > 'Stop Temperature'.

5.3 Mode M2: Timer with Temperature Control (Day/Night Cycle)
M2 mode allows you to set two different temperature ranges for two distinct time periods within a 24-hour cycle, ideal for simulating day and night conditions.
- Press 'M' until 'M2 TC+Timer' is displayed.
- Press 'OK' to enter setting mode.
- Set 'Time 1 ON' (start time for the first period) and 'Time 1 OFF' (end time for the first period).
- Set 'Start Temperature TC1' and 'Stop Temperature TC1' for the first period.
- Set 'Time 2 ON' (start time for the second period) and 'Time 2 OFF' (end time for the second period).
- Set 'Start Temperature TC2' and 'Stop Temperature TC2' for the second period.
- The clock settings in M2 mode have a memory function, retaining settings for up to 2 weeks after a power outage.
5.4 Mode M3: Timer Only
M3 mode functions as a simple timer, allowing you to set specific ON and OFF times for the connected appliance.
- Press 'M' until 'M3 Timer' is displayed.
- Press 'OK' to enter setting mode.
- Set 'Time 1 ON' (when the appliance turns on).
- Set 'Time 2 OFF' (when the appliance turns off).
- The clock settings in M3 mode have a memory function, retaining settings for up to 2 weeks after a power outage.
