G. Troubleshooting problems where a Hard Lockout Code is displayed. When a hard lockout occurs, the boiler will shut
down, the display will turn red and the “Help” button will “blink”. Select the “blinking” “Help” button to determine the
cause of the Hard Lockout. Once the condition that caused the lockout is corrected, the boiler will need to be manually reset
using the Reset button on the “Active Fault” display or located on the Sage2.1 Control.
Lockout Number Condition Possible Cause
4
Supply high limit
Sage2.1 supply sensor detected
temperatures in excess of 210°F.
• Heating load at time of error was far below the minimum ring
rate of the boiler.
• Defective system circulator or no ow in primary loop.
• Defective boiler circulator or no ow in boiler loop.
• Control system miswired so that the boiler operation is
permitted when no zones are calling.
5
DHW high limit
Sage2.1 DHW sensor detected
temperatures in excess of Setpoint.
• DHW load at time of error was far below the minimum ring
rate of the boiler.
• Control system miswired so that boiler operation is permitted
when no DHW are calling.
6
Stack High limit
Sage2.1 Flue gas (Stack) sensor detected
temperatures in excess of 204°F.
• Heat exchanger needs to be cleaned.
• Boiler over-red.
• Air-fuel mixture out of adjustment - consult factory.
12
Flame detected out of sequence
A ame signal was present when there
should be no ame.
• Defective gas valve - make sure inlet pressure is below
maximum on rating plate before replacing valve.
18
Light off rate proving failed
Blower is not running at Light-off rate
when it should or blower speed signal not
being detected by Sage2.1.
• Loose connection in 120 VAC blower wiring.
• Loose or miswired blower speed harness.
• Defective blower
19
Purge rate proving failed
Blower is not running at Purge rate when
it should or blower speed signal not being
detected by Sage2.1.
• Loose connection in 120 VAC blower wiring.
• Loose or miswired blower speed harness.
• Defective blower
20
Invalid Safety Parameters
Unacceptable Sage2.1 control Safety
related parameter detected.
Safety Parameter verication required. Contact factory.
21
Invalid Modulation Parameter
Unacceptable Sage2.1 control Modulation
related parameter detected.
Reset the control.
22
Safety data verication needed
Safety related parameter change has
been detected and a verication has not
been completed.
Safety related Sage2.1 control parameter has been changed and
verication has not been performed.
23
24VAC voltage low/high
Sage2.1 control 24Vac control power is
high or low.
• Loose connection in 24Vac VAC power wiring.
• Loose or miswired 24Vac harness.
• Miswired wiring harness causing power supply short to
ground.
• Defective transformer.
• Transformer frequency, voltage and VA do not meet
specications.
24
Fuel Valve Error
Power detected at fuel valve output when
fuel valve should be off.
• Loose or defective gas valve harness. Check electrical
connections.
• Defective gas valve (check for 24 Vac at harness during trial
for ignition before replacing valve).
25
Hardware Fault
Internal control failure. • Reset the control. If problem reoccurs, replace the Sage.
26
Internal Fault
Internal control failure. • Reset the control. If problem reoccurs, replace the Sage.
27
Ignition failure

Soft Lockout Flame failure after 5 tries to
restart.
• No gas pressure.
• Gas pressure under minimum value shown on rating plate.
• Gas line not completely purged of air.
• Defective Electrode.
• Loose burner ground connection.
• Defective Ignition Cable.
• Defective gas valve (check for 24 Vac at harness during trial
for ignition before replacing valve).
• Air-fuel mixture out of adjustment - consult factory.
