water temperature

The 832 relay is the reason you can't get hot water from the coil. It won't shut down the circulator like the 845 will, when it reaches a pre-set minimum temperature on the triple aquastat. The 832 is suitable for a boiler without a coil.

Stoker-man, thanks for the info on the 832 vs. the 845. I will order 2 845's.

Thanks,

Mark
