goodday all
well we went to use the air con (full reverse cyle) on heat the other morning as it was a bit cool air con wouldnt go, got out my faithfull tester yes we have powe.r get out manual seems Dometic wont go under 4 degrees they have an ambient cutout so at this point of time it seems i have a piece of junk sitting on the roof when it is cold just finishes me with WINDSOR and thier Dealer Southern Windsor we wanted the IBIS remote control unit but between them they were full of excuses why they couldnt fit IBIS

anyway WHAT WOULD THE CONSEQUENcES BE IF I BYPASS THIS CUTOUT SO WE CAN USE THE HEATING WHEN COLD
temperature cutsout at 4 degrees and back in at 7 degrees makes it totally useless as is

Steve, what model Dometic is it? Not the B1900 by chance?

I'm glad I ain't too scared to be lazy

Hi Steve,
The low ambient cutout is to protect against evaporator ice-up.
You can try bypassing it but you may get ice-up. If so it may do no harm but it simply will not operate as a heat pump.

Steve Old Boy,

The curse of RC aircons is that they rely on extracting heat from the air to warm. When it is bloody cold they can't find much heat to salvage and go to sleep. That is to say they struggle when you need them most.

We had a an unpleasant stay at a resort in Mansfield during winter a few years back when the RC aircon couldn't keep the unit warm.

The much maligned Heron units use a different principle. They are an aircon for cooling, and for heating they simply use an element much like a conventional fan heater. We had one in our van and it kept us warm all night long in "knacker" weather.

Cheers,

Jim.

Thats right Our Heron has the element for heating and thought How cheap is that!

I only found out after looking parts up for the Heron on the net. Thing is I was trying to work out why there was so much condensation in the van when using the Heat setting Now I know.

I still think it a cheap and noisy unit though.

Sorry for the gripe.

You could go to Lightning Ridge Steve.

On the same thread as the hair dryer, buy a little fan heater from k-mart and pre heat the air in the van with it before turning on the a/c. As long as you get it above 4 deg you shouldn't have an issue.

Living in FNQ I haven't seen 4 deg for while...............except in the beer fridge!

Good luck guys.

Yep...experienced that with an air cond in my aunts van.

When I built my van I went for a full houshold reverse cycle. Plenty going around on motorhomes etc! Works a treat. kept the van at 22 degrees over summer in port macquarie...and it wasnt running the compressor all the time.

Will be fine this year in winter...just need a big generator to run it or a LONG extension lead. LOL
