APPLICATION

The R7910A SOLA HC is a hydronic boiler control system and
the R7911 SOLA SC is a Steam Control system that provide
heat control, flame supervision, circulation pump control, fan
control, boiler control sequencing, and electric ignition
function. It will also provide boiler status and error reporting.
Multiple boilers can be joined together to heat a system
instead of a single, larger burner or boiler. Using boilers in
parallel is more efficient, costs less, reduces emissions,
improves load control, and is more flexible than the traditional
large boiler.
