Setup

Follow these steps for the initial setup of your INKBIRD Plug-in Thermostat.

  1. Unpack the Device: Carefully remove the thermostat and its accessories from the packaging.
  2. Connect the Temperature Probe: Insert the temperature probe into the designated port on the thermostat. Ensure it is securely connected.
  3. Plug into Power Outlet: Plug the thermostat directly into a standard 120V AC power outlet. The LCD screen will light up.
  4. Position the Probe: Place the temperature probe in the environment where you wish to monitor and control the temperature. For example, in water for aquariums, soil for plants, or air for rooms. The IP67 rating allows for submersion.
  5. Connect Appliance: Plug your heating or cooling appliance (e.g., heater, fan, refrigerator) into the power outlet on the front of the thermostat.

Operating Instructions

The thermostat offers three main control modes: Temperature Mode, Cycle Time Mode, and Countdown Mode. Use the MODE button to switch between them, and the SET button to confirm settings. Use the UP and DOWN arrows to adjust values.

1. Temperature Mode

This mode allows you to set a desired temperature range for heating or cooling.

  1. Press MODE until "Temperature Mode" is indicated on the display (usually by showing START and STOP temperatures).
  2. Press SET to enter setting mode. The "START" temperature will flash.
  3. Use UP/DOWN to adjust the desired start temperature. Press SET to confirm.
  4. The "STOP" temperature will flash. Use UP/DOWN to adjust the desired stop temperature. Press SET to confirm and exit setting mode.

Heating Mode: If START Temperature < STOP Temperature, the device will activate when the temperature drops to START and deactivate when it reaches STOP.

Cooling Mode: If START Temperature > STOP Temperature, the device will activate when the temperature rises to START and deactivate when it drops to STOP.
