XIV. Troubleshooting (continued)
C. 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 pump or no ow in primary loop.
• Defective boiler pump 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 of
f rate proving failed
Blower is not running at Light-off rate
when it should or fan speed signal not
being detected by Sage2.1.
• Loose connection in 120 V
AC fan wiring.
• Loose or miswired fan speed harness.
• Defective fan
19
Purge rate proving failed

• Defective fan
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 24V
ac 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 V
ac 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.
