3.8 Outdoor Sensor Placement

The outdoor sensor measures air temperature out-

side the building. It is important that the sensor is

located on the outside of the building on the north

facing wall. Failure to mount the sensor on the north

facing wall will result in artificially high temperature

readings. If possible, locate the sensor high under an

eve to prevent incorrect readings from direct sunlight

and damage due to the elements.

FIGURE 10: Outdoor Sensor Placement

Mount the outside sensor with the sensor module

facing down to prevent accumulation of dirt or water.

3.9 Outside Air Supply

If an outside air blower is to be used, See Page 17,
