4. Setup

4.1. Initial Charging

4.2. Connecting the Thermostat

1. Plug the VASNER VUTS1 thermostat into a standard 230V wall socket.
2. Plug your electric heating appliance (e.g., infrared heater) into the socket on the front of the thermostat. Ensure the heating appliance is switched on and ready to receive power from the thermostat.
3. The thermostat is now ready for operation.

5. Operating Instructions

5.1. Setting Current Time and Day

1. Press and hold the Set (i) button until the time display flashes.
2. Use the Plus (+) or Minus (-) buttons to adjust the hour. Press Set (i) to confirm.
3. Adjust the minutes using Plus (+) or Minus (-), then press Set (i) to confirm.
4. Adjust the day of the week (1 for Monday, 7 for Sunday) using Plus (+) or Minus (-), then press Set (i) to confirm and exit time setting mode.

5.2. Manual Temperature Adjustment

In normal operating mode, press the Plus (+) or Minus (-) buttons to manually adjust the desired temperature. The new setting will be active until the next programmed time slot or until a different mode is selected.

5.3. Operating Modes

Press the Mode (Fce) button to cycle through the following modes:

• Comfort Mode (23 °C default): Maintains a comfortable temperature. You can adjust the default comfort temperature in programming mode.
• Absence Mode (17 °C default): Maintains a lower temperature, suitable when the room is unoccupied. You can adjust the default absence temperature.
• Anti-frost Mode: Prevents the temperature from dropping below a critical level (e.g., 3-5 °C) to protect against freezing.
• Program Mode: Activates the weekly programmed schedule.

5.4. Window Open Detection

The thermostat can detect a sudden drop in temperature, indicating an open window. When detected, it will temporarily switch off the heating to save energy. Heating will resume automatically after a set period or when the temperature stabilizes.

5.5. Child Lock / Keypad Lock

To prevent accidental changes, activate the child lock by pressing and holding the Plus (+) and Minus (-) buttons simultaneously for a few seconds. Repeat the action to unlock the keypad.
