Update on the resistor, I ended up with a 17.2k resistor (15k + 2.2k in series) and I think it is just right, in the evening when it cools down and I'm wearing shorts and a t-shirt, right when I think "its a little cool in here" I can get the heater to turn on if I turn the thermostat to the max setting. This is of course an extreme example as if I were really somewhere cold I'd just have more clothes on. This assumes the lowest setting is around 35-40 degrees which I think it will be,and I'll be able to test that out when I get home in a week or so.

Is this on the Sprinter, or did you get another Vanagon? |
El sprinter.
|
I know that is no Vanagon, but inquiring/interested minds would like to see what you've done with the interior. My 'next' camper is going to be a custom Sprinter also.  |
I'll start a thread in the Off Topic forum in 5 days or so and post a link here, I will be on a river trip till the 4th  I'm just waiting for my wife and friends to get here and we'll be on the water tomorrow morning!

In the older Compact 1600 the post purge cycle is controlled by a 60 degree n/o thermostat in the heater, but of course under normal running that temperature would not be reached unless the heater was forced to run hot.
If that thermistor was changed for a 50 degree thermostat it may persuade it to come on more readily. |
Thanks Karl, that's good info, and I'll try it out. If I can't get that to work, I'll just use a time delay relay to energize the fan circuit when the thermostat shuts the furnace down.

We've had a bit of a warm spring here o I haven't been able to test this out as much as I'd like, but we did get to 32* a couple days ago, and I had to turn the dial down to ~%30 of its max setting to get the heater to turn off, so the lowest setting is probably about 20*?. This is with 17,200k of resistance.
So, the 15k ohm resistor will probably be just about right all in all, yea, imagine that, the guys that designed it had the right idea right off the bat.
We're supposed to be down to 28* Saturday morning so I'll check where the 15k resistor puts the low end of the thermostat then.

Hey Jack,
Any updates on where the 15k resistor puts the low end of the thermostat?
Much thanks for your experiments! |

Perfect! thanks again
Sounds like a very nice sweet-spot. Just warm enough to keep things from freezing at night, and still a lot of range to get you nice and toasty after an especially cold winter outing. |

I think where you install the thermostat is important, as well. Too far away from the heater, and the heater will never shut off when it's really cold outside. Also, I'd keep the t-stat away from the windows and don't mount it to any body metal.

YES!
The colder it is outside, the warmer the propex will keep the interior, if you have the thermostat mounted to the body metal.

Their Photobucket membership expired, I assume, so they blur the images. That's why it's always best to put your pictures directly on The Samba so they are there forever. Assuming The Samba is here forever and it darn well better be... I rely on it too much for it to ever go away!

Hi Jack - do you happen to have install photos of your HS2800? I am about to install mine under the rear bench, passenger side with the rear heater still installed. Its a tight fit and i looking for how others managed it.
cheers!
