A follow up question. The dealer told me to leave the pellot feed rate at 4 and forgot about it. He also said that he liked stove mode better than room mode because the fan isn't variable in stove mode. I've read online that a lower feed rate (like 3) and higher room mode temp will actually burn more efficiently. Thoughts? Also, in room mode, if the fan is variable, how come when I turn the deal closer to H, the fan speed increases? I thought the thermastat controlled the fan speed? Thanks very much!
