F06F06 Minimum Modulation Capacity
Increases lowest modulation rate during any call for heat.
0% -9% to +8%
F07F07 Gas Valve Ignition Capacity
Increases or decreases gas valve position during burner ignition. For example,
increasing this value causes gas valve to be more open (more fuel) during ignition.
0% -16% to 14%
F08F08 Blower Ignition Capacity
Increases or decreases blower speed during burner ignition. For example, increasing this
value causes the blower speed to be higher (more air) during ignition.

502502 DHW Priority Time
When DHW Priority Time is greater than zero and DHW heat demand is present, DHW
demand has priority over heating demands for this specified time. After DHW demand
ends or DHW Priority Time is exceeded; and CH demand is present, CH demand has
priority over DHW demand.

511511 Auxiliary Thermostat Input Select:
May be used as "Recirculation Enable", "Indirect Water Heater (IWH) DHW demand"
(heating boilers only) or "CH Zone 2 Heat demand" input.
(0) Recirculation Enable Recirculation enable input. When Comfort Mode is enabled,
"Aux Pump" output is energized to run a recirculation pump
when this input is "On". This input may be (a) jumpered
allowing recirculation pump to run at all times, (b) wired to a
time of day clock, or (c) wired to a momentary pushbutton.
Note: recirculation pump continues to run for 15 minutes
after this input is removed.

Boiler Only)
(2) CH Zone 2 Thermostat CH2 heat demand.
