Alerts and Delta T Diagnostics
with the Prestige® 2.0 IAQ
Thermostat
MOUNTING LOCATIONS
Refer to the guidelines below and Fig. 1–5 for
mounting locations of the Discharge and Return Air
Temperature Sensors.
Discharge Air Temperature
Sensor Mounting Location
1. Mount the Discharge Air Temperature Sensor
on the supply duct in a location where the air is
mixed well. Mount the Discharge Air
Temperature Sensor out of sight of the A-
Coil/Heat Exchanger when possible. See Fig. 1.
2. When possible, mount the Discharge Air
Temperature Sensor upstream of a Steam
Humidifier, a Fan Powered Humidifier or a
Dehumidifier that is ducted to the supply. See
Fig. 2–3.
3. If space does not allow a Discharge Air
Temperature Sensor upstream of a Steam
Humidifier or Fan Powered Humidifier, mount
the Discharge Air Temperature Sensor
downstream of the Humidifier. See Fig. 2. When
setting the Delta T Limits (see “Set Delta T
Limits” on page 5), be sure to consider the
affect that the humidifier has on Delta T.
4. If a Bypass Humidifier is installed, the
Discharge Air Temperature Sensor can be
mounted downstream or upstream of the
Bypass Humidifier. Mounting the sensor
downstream of the Bypass Humidifier is the
preferred location, because the air is mixed well.
See Fig. 4–5.
Return Air Temperature Sensor
Mounting Location
1. Install the Return Air Temperature Sensor on
the return duct in a location where the air is
mixed well. Mount the Return Air Temperature
Sensor downstream of a Bypass Humidifier,
Dehumidifier or Ventilator. See Fig. 1–5.
