Numeric Entry
When the Outlet Temperature exceeds the
Temperature
Hi Limit
by 5 to 15°F, the effective Fire Rate will be
reduced by the value entered in GOV Limit-5
through GOV
Limit-15
(0
– 100°F).
Above 70F Val
Numeric Entry
If the inlet water temp is above 70F, algorithm adds offset
provided by this item to all the 11 breakpoints (“breakpoint
at 100” – “breakpoint at 0”). (-10 - +10°F)
Below 70F Val
Numeric Entry
If the inlet water temp is below 70F, algorithm adds offset
provided by this item to all the 11 breakpoints
(“breakpoint
at 100” – “breakpoint at 0”). (-10 - +10°F)

Purge Control
Purge Blower Voltage
Numeric Entry
Sets the blower speed (blower output voltage) during the
Purge cycle (2.0 to 10.0 V).
Purge Timer
Numeric Entry
Allows adjustment of the pre-ignition purge time (5 to 60
sec.).
Post Purge Timer
Numeric Entry
Allows adjustment of the post purge time before the unit
shuts down (0 to 60 sec.).

Ignition Control
Ignition Position
Numeric Entry
Sets the air fuel valve position at which the unit will operate
during the ignition sequence (5% to 60%).
Ignition Blower Voltage
Read Only
Displays the actual blower voltage during ignition.
Ignition Voltage Offset
Numeric Entry
Allows an adjustment to the blower voltage during ignition
(-5.00 to 5.00).
Low Fire Timer
Numeric Entry
Specifies how long to remain in the low fire position after
ignition, before going to the desired output (2 to 600 sec.).
Ignition Hold Timer
Numeric Entry
Sets the length of time the unit stays in ignition position (0
to 60 sec.).
IGN Time Setting
Read Only
Displays the maximum time between confirmation of gas
valve opening (POC) and a stable flame detected.

Operating Control
Start Valve Position
Numeric Entry
Specifies the valve position at Start Level (0 to 40%).
Stop Valve Position
Numeric Entry
Specifies the valve position at Stop Level (0 to 40%).
Max Valve Position
Numeric Entry
The maximum valve position for unit (40 to 100%).
Standby Blower Voltage
Numeric Entry
Specifies the blower voltage in Standby Mode, during
which the blower motor remains “ON” at low speed, to limit
power cycles. AERCO recommends keeping the default,
however, may set this
between
2.00
and
0
volts on
individually vented units in positive pressure mechanical
rooms to compensate (0.0 to 10.0V).

Vlv Position Change Rate
Numeric Entry
Defines the rate at which the
valve position
will progress
from one step to the next (0.5 to 60 sec.).
Skip Range Cntr
Numeric Entry
Together, these 3 parameters define an optional Fire Rate
the Controller will skip-over (
Skip Range Cntr
= the center
of the range)
.
These can be used to reduce objectionable
noise at a certain Fire Rate, if there is no other remedy.
