    Haven't been on this sight much for the past several years, which is good 'cause that means everything is running fine, but...
    My Tarm 140 is about 9 year old. My question concerns the logic controller (which controls both the wood boiler and the oil boiler) the aquastats, the zone valve, and the (2) three-way valves. I installed the whole system myself, so I know my way around somewhat. I'm thinking I just need to follow the voltage, but the actual path is not apparent to me.

    Any help would be greatly appreciated.
