Rinnai I Series User Manual

Rinnai I-Series Condensing Boiler Combi Manual 93
Boost mode allows the boiler to override the target temperature determined by the outdoor reset
control, and will boost the boiler target temperature to the seng of Parameter 01 aer a
connuous run me or an interval as selected in Parameter 02. The boost funcon is acve unl the
call for heat is sased or the boiler cycles o.
Boost mode works when the outdoor sensor detects higher outdoor temperatures than expected.
For example: In the case of selecng curve 1 on parameter number 01 and 30 minutes on parameter
number 02, outdoor temperature is 51°F, and supply temperature is 140°F. When the boiler
connues operang with ring for 30 minutes, the target supply temperature will rise toward 180°F.
This control connues unl shut down.

The maximum outdoor temperature parameter seng enables the boiler to shut down when the
outdoor temperature is higher than 77°F (25°C). This mode can prevent the boiler from operang
under warm condions unexpectedly.
Maximum outdoor temperature is selected by seng parameter number 03 to “77°F (25°C)” or
“No Maximum” (see secon “12.4 Parameter Sengs” for more informaon).
