My Attack has an RK2001AT2 controller, this controller has a temp sensor just above the HX tubes. When the exhaust temp reaches a certain point the controller is in "work mode".
I assume that once this temp is too low (below setpoint) the fan shuts off and "FUEL" is displayed, well now during a cold start once pump launch temp is reached the circulator contacts close and the fan stops, no matter what the stack temp is???????
During boiler burn-out same thing, once the fan stops on it's own and the water temp drops and the circulator turns off, the fan will come back on??????????
Any insight would be greatly appreciated. This has only started to happen, I just wonder if it's a certain set of events (temps) that makes this happen. I've been playing with some of the settings but it still happens from time to time.
THANKS
