WSK-24 Wireless Occupancy Solution

INSTALLATION INSTRUCTIONS

PRODUCT DESCRIPTION

The WSK-24 Wireless Occupancy Solution automatically controls HVAC equipment by determining when a room is occupied. The WSK-24 uses the combination of an occupancy sensor and a door switch to provide optimal control. The WSK-24 is packaged in a kit that includes the following components:

• One 24V dry contact receiver
• One wireless PIR (passive infrared receiver) occupancy sensor with mounting kit
• One wireless door sensor with mounting kit
• One wiring harness.

The receiver can be wired into any thermostat or controller that supports the connection of a remote setback device. The receiver communicates wirelessly to a PIR occupancy sensor, a door sensor, and an optional 2^nd door/window sensor. After the receiver determines that the room is unoccupied it closes a dry contact switch. After the thermostat or controller recognizes the contact closure, it places the thermostat in economy setback mode, which provides energy savings for when the room is unoccupied.

FEATURES

• Wireless system provides quick and easy installation
• Pre-configured door sensor and occupancy sensor
• Guest comfort is maintained by never turning off HVAC equipment when someone is in the room – even if they are sleeping
• Fuse protection
• Long battery life
• Low battery indication
• Receiver memory retained after power loss
• Optional sliding door/window sensor can be easily added
• Compatible with TB8575 fan coil thermostats
• Compatible with TB6575 fan coil thermostats, but requires separate 24 VAC transformer
• Compatible with T7350 / T7351 thermostats, but requires a separate relay to reverse relay logic
• Other thermostats might also require a separate relay; the WSK-24 closes the contact when occupied

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. 6 on page 5.
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. 9 on page 5.
3. At the receiver and press the black pushbutton three times for Zone 3 (see Fig. 5 on page 5). The red LED on the opposite side of the receiver will flash three times. See Fig. 5 on page 5 for location of the pushbutton and LED.
4. Open and close Zone 3 by moving the magnet away from the sliding door/window sensor and bringing it back to contact. The red LED on the receiver will flash another 3 times to indicate that Zone 3 is discovered.
5. Mount the sliding door/window sensor and magnet using the same mounting procedure as described in “Mounting the Door Sensor” on page 5.

After the sliding door or window is opened and left open for longer than 1 minute, the receiver closes the relay and the thermostat goes into the unoccupied economy mode. The overall delay depends on the delay that is programmed in the thermostat. The occupant cannot change the thermostat settings while the sliding door or window is open. As soon as the sliding door or window is closed, the thermostat returns to normal operation.

SENSOR DISCOVERY

NOTE: The WSK-24 Wireless Occupancy Solution comes with the front door sensor and the PIR occupancy motion sensor already discovered by the receiver. There should be no need to rediscover these devices. However, this information is provided for troubleshooting purposes.

Deleting all Sensors

1. Press and hold the black pushbutton (see Fig. 5 on page 5) on the receiver for six (6) seconds.
2. The red LED on the receiver flashes once to confirm that all sensors have been deleted.

Adding Zone 1 (Door Sensor)

1. Make sure the PIR sensor is covered.
2. Make sure the door contact is closed.
3. Press the black pushbutton on the receiver one time. The red LED on the receiver flashes once.
4. Now activate the door sensor by removing the magnet. The red LED on the receiver flashes once to confirm the device has been discovered.
5. Uncover the PIR sensor.

Adding Zone 2 (PIR Occupancy Motion Sensor)

1. Make sure the PIR sensor is covered.
2. Press the black pushbutton on the receiver two times. The red LED on the receiver flashes twice.
3. Now activate the PIR sensor by uncovering the sensor and moving in front of it. The red LED on the receiver flashes twice to confirm the device has been discovered.

Adding Zone 3 (Optional Sliding Door/ Window Sensor)

1. Make sure the PIR sensor is covered.
2. Make sure the sliding door/window contact is closed.
3. Press the black pushbutton on the receiver three times. The red LED on the receiver flashes three times.
4. Now activate the sliding door/window sensor by removing the magnet. The red LED on the receiver flashes three times to confirm the device has been discovered.
5. Uncover the PIR sensor.

SYSTEM TESTING

Perform the following to test the sensors.

Front Door Sensor & PIR Sensor

1. Position the jumper away from the pushbutton to set the minimal time delay (15 seconds).
2. Cover the PIR sensor so it cannot sense motion.
3. Open and close the front door sensor. The receiver closes its relay after 15 seconds, and you will hear the relay click on the receiver.
4. Wait for the thermostat to go into unoccupied mode. The overall delay will depend on the additional time delay that is configured in the thermostat.
5. Uncover the PIR sensor so that it can now sense motion.
6. The receiver opens the relay and the thermostat returns to occupied mode immediately.
7. Position the jumper back to the desired time delay. (See “Setting the Delay on the Receiver” on page 5.)

2nd Door Sensor

1. Open the 2nd door sensor. The receiver closes its relay after 1 minute, and you will hear the relay click on the receiver.
2. Wait for the thermostat to go into unoccupied mode. The overall delay depends on the additional time delay that is configured in the thermostat.
3. Keep the door open and move in front of the PIR sensor so that it can sense motion. The thermostat should remain in the unoccupied mode.
4. Close the 2nd door sensor. The receiver opens its relay and the thermostat returns to occupied mode immediately.
