Indirect water heater looks like this:
View attachment 4473
The condenser boiler that i have has its own line voltage(circulator pumps for indirect, heating zone, and boiler loop) and low voltage(heating t-stat, outdoor thermostat, and indirect t-stat) terminals. As you can see it isnt just a two wire hook up. How would this be wired if there are only two low voltage terminals on boiler labeled "indirect"? I also read in the manual that when wiring thermostats make sure they are not powered from another source, ie: transformer perhaps because you can risk burning out circuit board in boiler. Any idea how to wire this one?
