Do you find the pump "ticking" a problem? This seems to be the main complaint on Youtuber videos and some even buy a different pump but the cost of somme of the pumps defeats the cost effectiveness of getting a cheap Chinese heater :oops:

Although the connections in the picture are correct the guy has made a mistake labelling the JST plug side, the TxD and RxD are the wrong way round, which is only a problem if like me your JST plug has different colours to the one in the picture ;)
