Help needed again! Automatic change over on van not working!

[colyboy]

Hi to you all. Having a little problem with the automatic change over. When we are moving and or static , the automatic will stay on gas all the time.
Could it be the unit itself or will the unit need replacing. If using mains this works ok.
Regards Colyboy

Not quite sure I am understanding your question, but our fridge for example has the following logic in 'Auto'.

Is engine running?

• Yes = use12v
• Else = Is gas available?

- Yes = use gas
- Else = Is 230v available?
- Yes = Use 230v
- Else = Alarm, 'no service'.

Personally I think the last is the wrong way round in that it should use 230v before gas, but it's definitely the way it works.

If the gas is alight, and you start the engine it immediately switches to 12V.

Hopefully that is of some assistance.
