This is my second year using a Biomass40 with 500 gallons of storage. I have always used the following settings:
thermostat - 195
pump - 170
hysteris - 4
fd--
fb30
Starting at the end of last year the unit would shut down automatically at start up and "fuel" would be seen on the controller. This occurred within about an hour after starting the unit, very seasoned wood, clean boiler, clean chimney, gasification, blue flame, etc. I was told that by setting fd at - - that it would not shut down at start up. The problem continued and ultimately I received a new controller (under warranty) this year). The same problem is happening again with a new contoller. I should also point out that the boiler is not reaching the 195 thermostat setting so the fb30 is not to blame. That setting is working fine.
Again, I am still using the settings above, the boiler has a dedicated circuit of power, all of these settings worked for 6 months, but am frustrated that the system is shutting down automatically still. Today for example, the boiler and tank were at 140 and I started it, had a nice bed of coals, put in very seasoned wood. All was well, the system was getting up to 170, the pump would turn on and then shut off when the boiler temp dropped below 166. Then after some period of time the unit shuts down and "fuel" is on the controller. I have to hit stop and start and then the system will be fine for the duration of the night.
As you can imagine, it is very frustrating to have the unit shut down on its own. Has anyone experienced this. Anyone know how to correct.
Thanks,
Andrew
