sensors to the main fan unit
Supplied with the unit are four black leads each incorporating a
temperature sensor which is sealed at one end.
The sensor end of the leads connected to connection 1, 2 and 3
(see figure 16) should be located as follows:-
i)
Measuring the outside air temperature at the eaves.
(see figure 15).
ii)
Any two of 8.1, 8.2 and 8.3 as required.
With the cable sensors installed as described above, attach the
other ends of the cables to the appropriate connector block on the
main unit.
Fit the fourth temperature sensor in a suitable location in the home.
Select a position unaffected directly by heating radiators or possible
draughts from opening windows. Using a small screwdriver, pierce
a hole in the corner of the ceiling and push the end of the sensor
through until it just protrudes into the room.
Connect the other end of the sensor cable to the fourth connector
block (Figure 16).
