SECTION 3: INSTALLATION

3.7 Indoor Sensor Placement

The sensor measures the air temperature in the

building. It is important that the sensor is located in

an area within the heated zone at occupant level. For

the most accurate results, sensors should be

mounted on an inside wall, away from any air vents

or other sources of heat and cold. In order to avoid

short system cycles and inaccurate temperature

readings, do not mount sensors under the first

section of radiant tube (first 10’ (3 m) section of tube

after the burner). The sensors are suitable for

direct surface mounting or 4" x 2 1/8" junction box

mounting.

display, grasp the green plug-in board at the lower

corners and gently pull the board away from the

sensor back plate. See Figure 9. After removing the

plug-in LCD display from its socket, secure the

sensor to the wall or junction box using the screws
