Error Description
Corrective Actions
E01
SUPPLY SENSOR
NOT CONNECTED
Supply sensor circuit is open.
1. Check sensor connection to be sure it is fully engaged.
2. Check continuity of both harness leads.
3. Read the temperature sensor value in the “User Menu” under
status. 14°F indicates an open circuit.
E02
RETURN SENSOR
NOT CONNECTED
Return sensor circuit is open.
E04
DHW SENSOR
NOT CONNECTED
DHW Sensor is open. (DHW
Mode 1 only)
E05
FLUE SENSOR NOT
CONNECTED
Flue sensor circuit is open.
Check the flue sensor as described above. 50°F indicates an open
sensor in the “User Menu” in this case.
E11
SUPPLY SENSOR SHORT
Supply Sensor is short circuited.
1. Check wires for signs of damage.
2. If temporarily connecting the harness to another sensor clears the
error, the sensor is probably defective.
3. Read the temperature sensor value in the “User Menu” under
status. 255°F indicates a short circuit..
E12
RETURN SENSOR SHORT
Return sensor is short circuited.
E13
DHW SENSOR SHORT
DHW Sensor is short circuited.
E14
FLUE SENSOR SHORT
Flue Sensor is short circuited.
E19
COMMUNICATION ERROR
E2PROM ERROR
Internal software error.
1. Disconnect all external wires except for the 120 VAC control
power.
2. If problem is corrected, systematically replace wires to determine
which pump/sensor is malfunctioning.
3. If problem persists, replace the control.
E20
FALSE FLAME DETECTED
Unexpected flame was detected.
1. Verify that no flame or spark is present.
2. Check & clean flame sensor.
3. Check boiler ground by assuring 0-5 VAC between neutral and
ground.
E21
HOT/NEUTRAL REVERSED
Polarity of power supply wires is
reversed.
1. Reverse polarity of power supply wires.
2. Check boiler ground by assuring 0-5 VAC between neutral and
ground.
E22
POOR GROUND
No earth ground connected or
internal hardware error.
1. Check boiler ground by assuring 0-5 VAC between neutral and
ground.
2. Check incoming frequency (hz) if power supply is from a
generator.
E23
NET FREQUENCY ERROR
Frequency of incoming power is
< 40 hz or > 70 hz.
1. If power supply is from a generator, check that the system is
phase/neutral (line voltage between hot/ground).
2. Check boiler earth ground by assuring 0-5 VAC between neutral
& ground.
E24
POOR GROUND
No earth ground connected or
internal hardware error.
1. Check boiler ground by assuring 0-5 VAC between neutral and
ground.
2. Check incoming frequency (hz) if power supply is from a
generator.
E25
BLOCKED VENT
Combustion chamber pressure
exceeds 4.5” w.c.
1. Check for blocked exhaust outlet.
2. Check the combustion chamber pressure (height difference
between condensate vessels).
