Eberspacher mini controller

[Slinky Spring]

I currently have a rotary rheostat type control on my eberspacher D2. I have a problem because the heater is fitted in an enclosed space. The heater runs fine for a while then shuts down. I believe this is because the unit is sensing that the incoming air is warm enough(because the enclosed space is warming up) and the internal detector shuts it down. I therefore think I need a controller that has a built in thermostat.

My question is does the mini controller have a thermostat or is it just a more modern version of the rotary switch I already have. I have bought one of these already but may stick it back on ebay if its not the right one.
Some posts on here have described the mini controller as a thermostat but the technical specs do not seem to suggest that this is the case.

I suspect the unit I require is this one.

Any advice welcomed

Slinkey Spring,

Yes, I think you are correct.

I too had the basic rheostat controller and have just replaced it with the digital 701 controller, this has a separate external temperature sensor. I think most of them now have this. I too was a bit unsure about the need so I rang Eberacher directly who were very helpful, they put me onto Krueger who were equally helpful, they may be worth calling too

Keep the rotary control you have and fit an external temp sensor,
part # SKU: 25.1774.89.03.00, no need for anything more complex unless you need a timer.

Yes, I have the simple rotary control and a separate room thermostat as per David's recommendation. This set up works perfectly - no need for the fancier controllers.

Thanks for the advice. Pity that the external sensor is so expensive.

£47 on the link above. I might as well pay £49 for the other controller which includes fault codes and then try to get a few bob back for the rotary switch on ebay.


Unless anyone knows where the sensor can be got cheaper?

Mind where you stick it.

Do bear in mind the siting of the sensor, the most effective place for it may not be the best place for the control head if they are combined. Otherwise I agree, the price difference does not make a lot of sense. Also if you do see a digital control cheap on ebay or elsewhere beware of the 80110001 designation, it will only allow the heater to run for an hour and will shut down after that.

Getting the other controller won't solve your problem, you still need the external sensor to bypass the internal one. The last controller I fitted which gave fault codes (and allowed them to be reset) and timer, was IIRC more like £140, definately not £47.

I can see where you could me mislead by the "it's too cheap, that can't be right" maxim but the 80110003 has an INTERNAL sensor which is connected to the same circuit as you would the normal external sensor and bypasses the heaters own internal temperature sampler. It's real drawback and the reason I am not too keen on them is that you are restricted in the mounting location, that is to say you can't really put them anywhere the standalone sensor would not go, e.g. near galley, in a place that gets direct sunlight, in the path of a heating vent etc, they must be in an area where the temperature does not fluctuate due to external sources to get any real benefit from them and that can be inconvenient for operation and visibility of the unit.
