Outdoor Air Temperature Sensor (OAT)
An optional outdoor air temperature (OAT) sensor is provided in
the literature package. Install the sensor outdoors, typically on the
north side of the residence away from direct sunlight. Sensor
package includes an adhesive holder for the sensor. See Fig 20 for
wiring the sensor to the OAT plug on the fan coil or furnace unit
control board. Do not connect to the optional remote sensor
terminals (S1, S2) on the UI.
Humidity control uses the OAT to adjust humidity target when the
OAT drops into the cold range to prevent forming of condensation
on windows.
It also allows the UI to display outdoor air
temperature.
