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.
