WSK-24 Wireless Occupancy Solution INSTALLATION INSTRUCTIONS contact closure, it places the thermostat in economy setback mode, which provides energy savings for when the room is unoccupied. FEATURES 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 2nd 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 • 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 Contents Product Description 1 Features 1 Ordering Information 2 Specifications 2 Installation 3 Thermostat Configuration 3 Wiring 3 Setting the Delay on the Receiver 5 Mounting 5 Battery Replacement 6 Operation 7 Door (Zone 1) and PIR Occupancy Motion Sensor (Zone 2) 7 Optional Sliding Door/Window Sensor (Zone 3) 7 Sensor Discovery 7 System Testing 8 Front Door Sensor & PIR Sensor 8 2nd Door Sensor 8 Limited Two-Year Warranty 8 Customer Assistance 8 62-0300-01 WSK-24 WIRELESS OCCUPANCY SOLUTION ORDERING INFORMATION PIR Detection Pattern: Length: 3 to 8 meters when mounted 2 meters above the floor (see Fig. 1) When purchasing replacement and modernization products from your TRADELINE® wholesaler or distributor, refer to the TRADELINE® catalog or price sheets for complete ordering number.

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. 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. 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. 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. 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. 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. 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. 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. 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. Optional Sliding Door/Window Sensor (Zone 3) Adding Zone 2 (PIR Occupancy Motion Sensor) 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. 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. NOTE: The sliding door/window sensor is identical to the door sensor supplied with the WSK-24 Wireless Occupancy Solution. 1. 2. Adding Zone 3 (Optional Sliding Door/ Window Sensor) Remove the battery tab from the sliding door/window sensor. See Fig. 6 on page 5. 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. 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. 7 62-0300—01 WSK-24 WIRELESS OCCUPANCY SOLUTION 4. 5. 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. Uncover the PIR sensor. SYSTEM TESTING 5. 6. 7. 2nd Door Sensor Perform the following to test the sensors. 1. Front Door Sensor & PIR Sensor 1. 2. 3. 4. Uncover the PIR sensor so that it can now sense motion. The receiver opens the relay and the thermostat returns to occupied mode immediately. Position the jumper back to the desired time delay. (See “Setting the Delay on the Receiver” on page 5.) Position the jumper away from the pushbutton to set the minimal time delay (15 seconds). Cover the PIR sensor so it cannot sense motion. 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. 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.
