Hi! We have recently bought a Citroen relay but the heater control is flashing and we can’t figure out why.
The battery icon is flashing and EO1 ( not enough voltage ) is showing. The battery is12V which we think should power it.
Any advice gratefully received!!

If you can plug into ehu so the battery is on charge wait half an hour then try again. Diesel heaters are very sensitive to battery voltage as they have to follow a shutting down process to ensure the heat chamber is cool enough, so it needs to know there is enough in the battery to doo so. If you just stoped the heater there is a chance it will overheat, thats why the fan runs fora while whilst shutting down.

On start up those Chinese heaters can take about 10amp then reduce down once running. So you need a good battery supply. As said above you also need to ensure you follow the correct shutdown procedure.
12v is not fully charged.
Lots of info about these heaters on YouTube.

Thanks for that, we’ll give it a go! 😊

As above, though running the engine may help if you don't have access to EHU.

If it's a home conversion (or heater added by a DIYer), could be worth having a look at the wiring to decide if it's really man enough for the job - it's easy to put in wires that are under-rated, in which case you'll get a high voltage drop and make the system far more sensitive to the battery charge state than it should be.

Thankyou! We’ll give that a try! 😊
