Eberspacher issue!

[pcatterall]

The little controller you show would work fine. Note that it has a thermostat built in but if you want to use that the controll willl have to be 'indoors'.
Also has fan only which you would like, also has diagnostic capability which sound great .
All in an inexpensive unit.

Just looking at purchasing a new controller thingumabob and came across this one -
http://www.pfjones.co.uk/eberspacher-digital-controller-80110003.html

I gather this would also work with the unit? I'm a sucker for LCD screens!

This is the controller I have.
You will probably have to add an extra wire to your wiring loom for the temperature sensor to operate.
Also, be aware that you may have to set the temperature about 5 degrees higher for it to operate properly e.g. to maintain 20 degrees temp then set the required level to 25 degrees. According to the eber specialists in Lymington this is because some components fitted were diffferent to the designed ones (probably to save money!!). Pretty **** really!!!

One thing to make sure, according to the manual: If the desired temperature is exceeded while the heater is operating in low heat mode the heater will switch into “standby” mode. The heater will re-start once heat is required again

In the "standby mode" with an external sensor, the blower is also turned off. The Eberspächer appears to be dead/malfunctioning. Do you turn down the button to a lower temperature than you want?

My old heater did not turn off the blower. When I got my new Eberspächer I noticed the 'malfunctioning' after a year, called the serviceman and had to pay for getting the conclusion: everything is fine.

I'm not sure I follow. Are you saying that if the Eber is turning off due to it thinking the correct temperature has been reached, it should stop the heater however continue to blow air?

If I remember correctly, when I turn it down (say to half power on the current rheostat) the heater will first slow down a bit and behave as if it is pumping out less heat as requested. However, after around 5 minutes or so (not timed it, could be less) it will shut itself down.
Of note, and I don't know if it's important, the green power light on the rheostat stays on when this happens.

Sounds like the climate control in my car! Passengers are always shocked when they see 24ºC as the desired temperature!

I'll need to examine the wiring loom. At the moment it runs to just behind the rheostat and I think the unused wires have masking tape on them.

Dear Cardo
The Eberspächer also turns off the air blower when the temperature is right. My old heater did not turn off the air blower when the temperature was right (and therefore I thought the Eberspächer was malfunctioning).
I have the minicontroller (& thermosensor) in the cabin.

This 801.. Controller you have, how are the 3 heat/fan levels controlled? I have the mini controller on a D2 and it is a devil to keep it to a low tickover once the cabin has warmed up at full power and speed. All info welcome, I'm tempted to the 801.. if controll is ok
Thanks

I think I'll lob the silencer on the combustion air inlet and see how that works out. The heating isn't particularly noisy inside the boat, however makes one helluva racket outside. I'd feel for my neighbours in the marina if I ran the heater as it is now!

Most of the silencers around are exhaust silencers for fitting to Wagons and they leak should not be fitted in the same locker as the heater. I installed a D4 in place of the old DL3 and the noise from the exhaust is not acceptable when in a marina, but I have fitted a silencer into the exhaust skin fitting and it reduces the noise by half and works just fine.

I dont think the 801 or mini controller have any control of the 3 heat/fan levels used in the main heater - I think the 3 heat fan levels are controlled by the electronic control unit (ecu) in the heater itself.

I dont have a problem (as yet?) with a low tick over. I would offer to lend my controller to you but its 200 miles away at the moment. Perhaps you could 'borrow' an 801 from someone else?

Maybe your heater just needs a good service?

Well, that's the controller that I have for my D4 Airtronic, and it works perfectly. If I set it to 25º (Phew !), that's what I get.

Thanks for the info; will persevere , I find getting the D2 settled at a low setting a bit like getting a cutter on course in the wild ocean, turning the stat up and down betwixt cutting out and roaring away at full steam!
Thanks, Malcolm

sounds like it needs a service, you could do that.
I understand that it could be a blocked or slightly blocked air intake too, the hose on the heater.
All the heaters are noisy on full, I understand also that the airtronics temp is worked on the heater itself not the room temp.

 

[Cardo]

Just to clarify one last thing. The combustion air intake for my setup is in the cockpit locker and not led out of the boat.
Is there any problem with this?

The manual says the feed should come from outside the vehicle, however is this aimed more at small cabins where you would essentially be pumping air out of the cabin?

The cockpit is large and has quite a few vents, so air flow is good.
