Sensor Operations

Temporary Occupancy (Timed Override)
Temporary occupancy (timed override) is available on model
WDS. Temporary occupancy is selected for after-business-
hours adjustment of temperature setting, fan settings, or heat/
cool settings, when the system has changed to unoccupied
mode. System control will revert to unoccupied after a pre-
determined time period.
Note: Not all systems support the occupancy function.
To request and cancel temporary occupancy on a model WDS
sensor, see "Requesting Temporary Occupancy," p.
End-of-Range Temperature Values
Receiver: The end-of-range temperature limits of the receiver
for all models are 32°F to 122°F. The receiver cannot replicate
temperature values outside this range. If the sensor transmits
a temperature value to the receiver that is out of the receiver
replication range, the receiver will "freeze" the output at the
end-of-range values. This value will remain frozen until the
transmitted temperature moves to between the end-of-range
temperature limits.
Sensor: The end-of-range temperature setpoint limits for the
WDS is 50°Fto 89.6°F.
Receiver Power-up Sequence
When power is applied to the receiver, one of the following
sequences occurs. The sequence is dependent on the
address setting and the association status of the receiver.
Address set to 000 and receiver is not
associated with a sensor
• LED5 is constantly On, indicating power is applied and the
receiver is functional.
• All models: Zone temperature and cooling setpoint default
to 72.5°F.
WDS only: The heating setpoint defaults to 70.5°F and the
fan/system output will be 2230 Ω (see
Modes," p. 102).
• Status LED3 will display a 2-blink pattern diagnostic
(Table 38, p. 98).
Address set from 001 to 999 and receiver is
not associated with a sensor
• LED5 is constantly On, indicating power is applied and the
receiver is functional.
• All models: Zone temperature and cooling setpoint default
to 72.5°F.
WDS only: The heating setpoint defaults to 70.5°F and the
fan/system output will be 2230 Ω (see
Modes," p. 102).
• The receiver conducts an energy scan for 20 seconds to
determine the clearest channel on which to operate.
