TROUBLESHOOTING GUIDE

Alarm Messages

Alarm Messages are shown one at a time in priority order. The message closest to the top of this list is displayed first.

Following messages are not shown until the higher priority message has cleared. All alarm messages are also stored

in the Fault History.

Alarm Message

Recommended

Action

Explanation

Low Water Level

Manually Reset the Low

Water Cutoff

Low Water Cutoff Switch

When this option is configured and an instrument is installed, the manual reset

low water safety relay is preventing the boiler from starting. If terminal (LC) does

not receive power and the Call For Heat output (CH) is powered, the “Low Water

Level” Message is displayed.

Off Switch

Turn Burner Switch On

Burner Switch is Off

Control switch is in the OFF position and is preventing the boiler from starting. If

terminal (OO) does not receive power and the Call For Heat output (CH) is pow-

ered the “OFF Switch” Message is displayed.

Low Water Flow

Ensure Boiler Pump is

Running and Boiler

Water Flow is

Unobstructed

Low Water Flow Switch

Low water flow is preventing the boiler from starting. If terminal (WF) does not

receive power and the Call For Heat output (CH) is powered, the “Low Water

Flow” Message is displayed.

Fuel Limit

Manually Reset the Fuel

Pressure Switch

Low or High Gas Pressure Switch

The low or high gas pressure switch is preventing the boiler from starting. If

terminal (GP) does not receive power and the Call For Heat output (CH) is

powered the “Fuel Limit” Message is displayed.

High Temp Limit

Manually Reset the

High Temperature

Aquastat

High Limit Temperature

The high temperature limit (HL) (and operational temperature limit when

provided) aquastat is preventing a boiler start. If terminal (HL) does not receive

power and the Call For Heat output (CH) is powered, the “High Temp Limit”

Message is displayed.

Low Air Flow

Check Combustion Air

Blower and Air

Pressure Switch

Settings and Wiring

Low Air Flow or Blocked Vent Switch Not Made

The air flow (and blocked vent switch when installed) is preventing a boiler start.

If terminal (CA) does not receive power and the Call For Heat output (CH) is

powered, the “Low Air Flow” Message is displayed.

FSG Fault

Manually Reset

Required, Refer to

Flame Safeguard

Manual

Corrective Actions

Flame Safeguard Fault

The Flame Safeguard is preventing a boiler start. If terminal (AL) receives power

at any time, the “Flame Failure” Message is displayed.

Outlet Temp Fail

Check Wiring and

Sensor

Boiler Outlet Temperature Sensor Fail

The boiler outlet temperature sensor is not connected or is reading above or

below a valid range. When the boiler outlet sensor fails and the Outlet Sensor

mode was selected, the control will transfer to Lost Sensor Blind Mode.

Inlet Temp Fail

Check Wiring and

Sensor

Boiler Inlet Temperature Sensor Fail

The boiler inlet temperature sensor is not connected or is reading above or below

a valid range. When the boiler inlet sensor fails, the mixing valve output will drive

to 0% and low temperature alarm and maximum water differential (boiler outlet

minus boiler inlet) temperature hold are disabled.

OA Temp Fail

Check Wiring and

Sensor

Outside Air Temperature Sensor Fail

The outside air sensor is configured and is not connected or is reading above or

below a valid range. When the outside air sensor fails, the warm weather shut-

down (WWSD) and outside air reset control logics are disabled.

Remote Temp Fail

Check Wiring and

Sensor

Remote System Temperature Sensor Fail

The remote system temperature sensor is configured and is not connected or is

reading above or below a valid range. If Remote System Temperature Sensor

mode was selected, the control will transfer to Boiler Outlet Sensor Mode.
