Central Heat Maximum Expected Heat Rate
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 Expected Heat Rate (fan speed) setting to limit the
boiler output accordingly.

Domestic Hot Water (DHW) Maximum Expected Heat Rate
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 Expected Heat Rate (fan speed) setting to limit the
boiler output accordingly.

Auxiliary Maximum Expected Heat Rate
This parameter defines the highest modulation rate the Control will go to during the auxiliary heat
call for heat. If the rated input of the Auxiliary Heat Zones is less than the maximum output of the
boiler, change the Auxiliary Heat Maximum Expected Heat Rate (fan speed) setting to limit the
boiler output accordingly.

Zone 1 Expected Heat Rate (typical for zone 1 through 16)
This parameter defines the highest modulation rate the Control will go to dur-
ing the Zone 1 call for heat. If the rated input of the installed home radiation in
zone 1 is less than the maximum output of the boiler, change the Zone 1 Ex-
pected Heat Rate (fan speed) setting to limit the boiler output accordingly.

Zone Release Time
After the Zone Release Time minutes and a zone has not been satisfied (thermostat opens) the
measured heat loss will be released to increase to the Central Heat Maximum Heat Rate.
