WSK-24 WIRELESS OCCUPANCY SOLUTION OPERATION

62-0300ES—01 6

a. Wall Mount option 1: Use the adhesive tape to

secure the PIR back plate to the wall.

b. Wall mount option 2: Using either the top or

bottom two holes of the PIR back plate, insert

the two long screws to secure the PIR back

plate to the wall.

c. Ceiling mount option: Align the mounting

bracket and PIR back plate as shown in Fig. 10.

Insert the two small screws into the top holes of

the back plate and secure it to the bracket. Use

the two long screws (and, if necessary, the

optional plastic anchors) and mount the bracket

and PIR back plate to the ceiling.

4. Replace the PIR sensor cover and replace the

cover release screw on the bottom of the sensor.

CHECK THE PIR OCCUPANCY MOTION SENSOR FUNCTION

1. Create motion in front of the PIR sensor and verify

that its LED flashes three times when motion is

detected.

• The PIR sensor continues to flash while motion

is detected.

2. Cover the PIR sensor and verify that its LED stops

flashing.

3. Uncover the PIR sensor.

Battery Replacement

For correct battery replacement, note the battery polarity

orientations in Fig. 11 and Fig. 12.

Low-Battery Indication

When a low battery condition is detected in the door

sensor or the PIR occupancy sensor, the LED status

indicator on the device flashes for four (4) seconds.

OPERATION

Door (Zone 1) and PIR Occupancy Motion

Sensor (Zone 2)

The door sensor and PIR occupancy motion sensor are

packaged factory-configured to the receiver. There is no

need for the receiver to discover these sensors. The door

and PIR sensors wirelessly connect to the receiver right

out of the box. Simply wire and mount the receiver and

sensors and the system will work properly.

When the door is opened and then closed, a signal is sent

to the PIR sensor to begin looking for motion. As soon as

the PIR senses someone is in the room, the receiver

clicks the relay to turn the thermostat back into the

occupied setpoints. If the person does not leave the room,

the thermostat will always stay in the occupied mode,

regardless if the PIR sensor stops sensing motion. This

provides a comfortable environment for guests and

ensures that the HVAC equipment does not turn off while

guests are sleeping.

When a guest opens and closes the door and leaves the

room, the PIR sensor starts looking for motion again. If

the PIR sensor does not sense motion, the receiver

closes the relay after 15 seconds or 3 minutes (depending

on how the jumper is positioned) and the thermostat goes

into the unoccupied economy mode. The overall delay

depends on the delay that is programmed in the

thermostat.

The PIR sensor always overrides the unoccupied

economy mode, as soon as it senses motion. For

example, if there are two guests in the room and guest A

is in the bathroom while guest B leaves the room, the

thermostat goes into economy setback mode if no motion

is detected. As soon as guest A leaves the bathroom and

enters the main room, the PIR senses motion and returns

the thermostat to normal operation. The thermostat

continues in normal operation until someone opens and

closes the front door and the PIR stops sensing motion.

Optional Sliding Door/Window Sensor

(Zone 3)

Because the sliding door/window sensor is an optional

accessory, the receiver needs to discover this new zone.

After the sliding door/window sensor is powered, follow

these steps to add the optional sliding door/window

sensor. It is easiest to do this before the sensor is

mounted.

NOTE: The sliding door/window sensor is identical to

the door sensor supplied with the WSK-24

Wireless Occupancy Solution.

1. Remove the battery tab from the sliding door/

window sensor. See Fig. 5 on page 4.

2. Make sure the sliding door/window sensor and

magnet are close to each other, within 3/4 in. (19

mm), and that the tab notches on the sensor face

the magnet. See Fig. 8 on page 5.
