Instruction for Use

Windowing function

If the window is opened and causes the room temperature to drop by more than 6°C within 4 minutes, the main screen displays 'OP' and closes the valve. This status can be cleared if the room temperature increases by 3°C, either automatically after 48 minutes or manually.

Anti-scale function

If the heat sink remains partially closed or is unused for an extended period, sedimentation may block the valve, rendering the heat sink unusable. To maintain optimal functionality, the controller will automatically fully open the valve every two weeks for a 30-second cycle. During this process, the screen will briefly display "Ad" before returning to its normal operating state.

Child lock function

To prevent accidental adjustments by children, activate the child lock function by pressing and holding the button when the device is powered on. The screen will show "LC" to indicate activation. To unlock, simply repeat the activation process.

Anti-freezing

When displaying the shutdown state ("OFF"), the antifreeze function is activated: the valve opens when the room temperature drops below 5°C and closes when the temperature rises above 8°C.

Low voltage warning function

When the battery voltage is too low, an alarm symbol " " will appear on the display to remind the user to replace the battery.

Temporary mode

When in programming mode, if you want to manually change the temperature of the current programming period, turn the knob to adjust the desired temperature, which will be maintained until the end of the current programming period.
