Flue Sensor
An optional Flue Sensor 069 can be installed on the boiler flue to measure the flue gas temperature . It is not
possible to have both a flue sensor and an indoor sensor installed at the same time as they share the same
auxiliary sensor input .
• Connect the wires to the Aux sensor terminals 8 and 9 .

Testing the Sensor Wiring
A good quality test meter capable of measuring up to 5,000 kΩ
(1 kΩ = 1000 Ω) is required to measure the sensor resistance .
In addition to this, the actual temperature must be measured
with either a good quality digital thermometer, or if a thermom-
eter is not available, a second sensor can be placed alongside
the one to be tested and the readings compared .
First measure the temperature using the thermometer and
then measure the resistance of the sensor at the control .
The wires from the sensor must not be connected to the con-
trol while the test is performed . Using the chart below, estimate
the temperature measured by the sensor . The sensor and
thermometer readings should be close . If the test meter reads
a very high resistance, there may be a broken wire, a poor
wiring connection or a defective sensor . If the resistance is very
low, the wiring may be shorted, there may be moisture in the
sensor or the sensor may be defective . To test for a defective
sensor, measure the resistance directly at the sensor location .
Do not apply voltage to a sensor at any time as damage
to the sensor may result.
Call customer service if you need assistance with technical details .
