Note
When using the sequential load feature of the IBC boiler, you must check the operation of system
components to ensure they are compatible. Many air handlers, for instance, use a thermostat
connection that energizes an internal relay to operate the air handler circulator and its fan on a
call for heat. Thus, these components may operate when other loads are running at a higher
priority, resulting in cold air blowing, or taking heat from another load. You may need to modify the
wiring to separate these functions from the thermostat control in favor of more effective control
from the IBC boiler.
