NOTES:
1. Locate the sensor where it will not be subject to
tampering.
2. Locate the sensor on an inside wall about 5 ft [1.5m]
above the floor.
3. Make sure the wire run between the sensor and the
controller is 300 ft [91m] or less.
4. Make sure there is good air circulation at average
temperature at the location. Avoid the following
locations because they can introduce errors in tem-
perature sensor measurements (Fig. 36):
a. Hot areas caused by:
1) Concealed pipes or ducts.
2) Drafts from fireplaces or other heat sources.
3) Convection or radiant heat from the sun or
electrical equipment.
b. Cold areas caused by:
1) Concealed pipes or ducts.
2) Drafts from windows and doors.
3) Unheated areas on the other side of the wall
location.
