Outside Air Sensor Wiring - Robertshaw Smart Sense Series Installation Manual

When used in Start / Stop Commercial Programmable Mode (Sw6 = ON, Sw8
= OFF), the after hours run timer can be toggled ON or OFF as required with a
momentary press of a button on the remote sensor. See Figure 20.

Outside Air Sensor Wiring

Set TT = OA in the Advanced Installer Menu
The SMART 2000 can display the outside air temperature if desired. Some
advanced control functions such as high and low balance points rely on this sensor
for correct operation. Using a single pair of wires, connect the TT terminals in the
thermostat to the two terminals in the outside air temperature sensor. See Figure
21. If the outside air sensor fails, two dashes will be shown on the LCD where the
outside air temperature would normally be displayed to alert you of the problem.
