I tried this and some other things i didnt save.

```cpp
  else if (mode == MODE_LISTEN_SLAVE) {
    if (OPENTHERM::isSent()) {
      OPENTHERM::listen(BOILER_IN, 800); // response need to be send back by boiler within 800ms
    }
    else if (OPENTHERM::getMessage(message)) {
      Serial.print("<- ");
      OPENTHERM::printToSerial(message);
      float f88();
      Serial.println();

```
