Press the Menu icon. 2. Press Schedule. 3. Press Schedule Options. 4.
Enabling the Motion Sensor (TEC3x21-00-000, TEC3x23-00-000 Models) By default on models with integral motion sensing capability, the motion sensor is enabled with a default timeout of 15 minutes from the last detection of motion in the zone. On models without an integrated sensor, the default timeout is still 15 minutes, but it only is applied when one of the two configurable binary inputs is set to be a motion sensor (see Configurable Binary Inputs for information on configuring the binary inputs).
Table 8: TEC3000 Tuning Types Tuning Type Description Deadband Override There is no deadband in use with proportional devices. This operates in the same way as Automatic PID tuning.
