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), in direct sunlight or in the path of other sources of radiant heat. The sensors are suit- able for direct surface mounting or 4" (10.2 cm) x 2.13" (5.4 cm) junction box mounting.

3.7.1 Indoor Sensor Mounting

Remove the cover of the sensor by the two 1/16" allen screws, located in the lower corners of the cover. To gain access to the top mounting hole, remove the plug-in LCD display. To remove the LCD display, grasp the green plug-in board at the lower corners and gently pull the board away from the sensor back plate. See Page 24, Figure 11. After removing the plug-in LCD display from its socket, secure the sensor to the wall or junction box using the screws provided. Replace the plug-in LCD dis- play and secure the cover with the two 1/16" allen screws.

Wiring from 32 V terminals on the controller to sensor power terminals "+" and "-" is polarity sensitive. Reversing polarity may cause sensor

or control board damage. Refer to Page 26, Figure 13 and Page 28, Figure 14 for wiring details.

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.

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 26, Figure 13 for external wiring diagrams. See Page 22, Section 3.4 for current load.
