Locking or Unlocking Settings. You can lock or unlock
the setpoint, system, or fan setting to prevent changes.
To lock or unlock a setting:
1. Verify that the sensor is in operating mode and at the
home screen.
2. Choose a setting to lock or unlock:
• S
elect the setpoint by pressing the up or down
arrow.
• From the system menu press the down arrow to
select the fan menu. Use the left or right arrow to
choose the setting.
3. Press the left and right arrows for 4 seconds.
Note: If you try to access a feature tha
t is locked, the
locked symbol will appear on the display.
If you press a keypad button to try change a locked
setting, the locked symbol will flash.
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.
Model WDS Sensor
To request and cancel temporary occupancy on a model
WDS sensor, see “Requesting Temporary Occupancy,”
p. 83.
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 model WDS sensor 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 recei
ver 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 “Output
Values—Failure and Default Modes of Operation
(Wireless Controls),” p. 121).
• Status LED3 will display a 2-bl
ink pattern diagnostic
(Tabl e 45, p. 11 8 ).
Address set from 001 to 999 and receiver is not
a
ssociated with a sensor
• LED5 is constantly On, indicating power is applied and
the recei
ver 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 “Output
Values—Failure and Default Modes of Operation
(Wireless Controls),” p. 121).
