Remotron heater - manual request

I have an early '80s heater in my boat. The model is Remotron from AB Thermotron in Sweden. It is a propane forced air heater. The company still exists but has moved on to other products. Apparently they stopped making these 20+ years ago. Does anyone have a manual they would be prepared to scan and send me? I have not been successful in tracking one down on the web.

The unit still works but it is intermittent in that it occasionally shuts off for no reason, or will not shutoff if the flame does not light. I have checked the furnace box and it is still intact and has a few more years life in it. There is a photoresistor that acts as a flame sensor and there is an over temperature switch. They are connected in series and the resistance does change depending on whether the flame sensor sees light or not but I have not yet been successful in identifying what resistance values are present when the unit is responds correctly to the signals versus when it does not. I am trying to decipher whether the sensors may be bad or the electronics. Unfortunately the electronics are epoxy potted and not likely accessible.

Thanks in advance,
Ken

Re: Remotron heater - manual request

Hi John,
I was not able to track any information down. I ended up removing the old controller entirely and making a new one myself. I used an Arduino microcontroller. It is probably as safe as the original control module but certainly not "failsafe". I would never run it unattended or while sleeping so I view this as an interim solution.

As to the plug - I assume you mean the spark plug for the ignitor. I just cleaned and reused the existing plug. It only sparks for a short time on start up and the quality of the spark is not particularly important to function. Any plug with similar dimensions of projection into the flamebox would be fine.

What state is yours in? Once I established that the flamebox and surrounding body were still sound I was prepared to have some fun getting it going again. If there is any doubt as to the integrity of the flamebox you should remove it - it is just too dangerous.

Hi jpbecton, I would be happy to provide more info. Currently I am away and only have my cell phone for internet. I will send more info in a couple of weeks. (Just pm me if it takes longer than that.)

Re: Remotron heater - manual request

Coincidentally I have the same symptoms, and would also be interested in your fix...the weather is getting cooler, and it would be nice to have a functioning heater...

Re: Remotron heater - manual request

Here is a poor quality scan of the schematic of my controller. If you send me a PM with an email address I can send you a legible version and the source code I wrote for the Arduino controller.

Google "Arduino" to learn about the controller - a simple, cheap, open source microcontroller.

Don't tell your insurance company you are using one of those in a boat.
