Anyone useing the Taco PC700 to control your coal stoker with Taco switching relay ? I use the taco switching relay to control my axeman anderson 130 witch is more btu's than I use for my house. I'm set up for 4 zones , house fan coil, indirect water heater, basement, and garage(not finished installing). My house is 1800 sq' and 90,000 btu's should cover the living space. The water is always sitting at the high limit (180) at idol. The Taco PC700 control takes into account the outdoor temp. to control the fire for btu's needed. I would not need to fire hard for the water heater and basement. Can the controll be set for the different zones ? Would I see much savings or just more unburned coal ? I use a timer set 1 minute every hour to prevent outfires. Guess it's just something else to fail ?
