3.4 CONNECTING THE <strong>PROBE</strong> CABLE<br />
Connect the probe lead supplied as shown in Figures 3.4a and 3.4b. Unheated probe leads have integral reference<br />
air tube. An adaptor has been supplied to connect this tube to quarter inch flexible PVC tubing, from the air pump<br />
or reference air supply.<br />
3.5 CONNECTING THE FLUE THERMOCOUPLE<br />
For heated probes the flue thermocouple must be a separate TC with the junction isolated from earth, mounted near<br />
to and upstream of the oxygen probe. It can be any one of types T, J, K, R, S or N. It is optional.<br />
If efficiency, oxygen deficiency, flue temperature display or transmitted signals are not required, then a flue TC is<br />
not necessary.<br />
For unheated probes the probe TC can also serve as a flue TC. For this option, jumper in copper wire from terminal<br />
3 and 4 to terminals 5 and 6 respectively. Remove link LK2 when connecting in this way.<br />

3.6 CONNECTING THE RELATIVE HUMIDITY SENSOR<br />
Refer to Section 2.12 for details on this optional input. Mount the relative humidity sensor in a position to sense air<br />
with equivalent RH to combustion air. For connection details refer Figure 3.6.<br />
