Description
1) Check to see if the Outdoor Sensor is
connected.
2) Check wiring connectons to outdoor sensor.
Outdoor Sensor
3) Remove wires from terminals #3 and #4 on
Open
the boiler and check the resistance between
them. If the reading shows an open circuit
there is an broken/disconnected wire or sensor.
Reconnect or replace.
1) Check wiring connection to Outdoor Sensor.
2) Remove the wires from terminals #3 and
#4 on the boiler and check the resistance
between them.
• If this reading is below 3000 Ω check the
Outdoor Sensor
Shorted
reading at the sensor.
• If the reading is the same at the sensor,
replace the sensor.
• If the reading is higher at the sensor, replace
the wiring.
1) Be sure the optional DHW Sensor (54157)
is connected.
2) Remove the wires from terminals #5 and
#6 on the boiler and check the resistance
between them.
DHW Sensor
a. If the resistance is above 10 k Ω, check the
Open
resistance at the sensor.
b. If the reading at the sensor is the same,
replace the sensor.
c. If the reading at the sensor is lower, replace
the wiring.
1) Check wiring connection to DHW Sensor.
2) Remove the wires from terminals #5 and
#6 on the boiler and check the resistance
between them.
a. If this reading is below 1000 Ω, check the
DHW Sensor
Shorted
reading at the sensor
b. If the reading is the same at the sensor,
replace the sensor.
c. If the reading is higher at the sensor, replace
the wiring.
1) Check wiring connection to flue sensor.
Flue Sensor
2) Compare sensor resistance to Figure 8.3.
Open
If resistance value is incorrect, replace sensor.
