Warning
Boiler type is factory set and must match the boiler model. Only change the boiler type setting if you are
installing a new or replacement Control. The boiler type setting determines minimum and maximum blower
speeds. incorrect boiler type can cause hazardous burner conditions and improper operation that may result
in PrOPErTY LOSS, PHYSiCaL inJUrY Or DEaTH.

Boiler Type
Boiler Size Setup
To verify the boiler size selection, a qualified technician should do the following:
1. Check boiler’s label for actual boiler size.
2. Set “Boiler Type” to match actual boiler size.
3. Select “Confirm”.
The Boiler Type parameter changes the minimum and maximum modulation settings. This
parameter is intended to allow a user to set the parameters in a spare part Sage2.1 Controller to a
particular boiler type.
See Table
30
Minimum to

Modulation
Central Heat Maximum Modulation
This parameter defines the highest modulation rate the Control will go to during a central heat call
for heat. If the rated input of the installed home radiation is less than the maximum output of the
boiler, change the Central Heat Maximum Modulation (fan speed) setting to limit the boiler output
accordingly.
See Table

Domestic Hot Water (DHW) Max Modulation
This parameter defines the highest modulation rate the Control will go to during a Domestic Hot
Water call for heat. If the rated input of the indirect water heater is less than the maximum output
of the boiler, change the DHW Maximum Modulation (fan speed) setting to limit the boiler output
accordingly.
