Welcome! Thank you for choosing the TrickleStar TS1921 Occupancy Sensor. This Occupancy Sensor is an accessory for the TrickleStar Wi-Fi Smart Thermostat. The Sensor helps the Thermostat to maximize comfort to your room as the sensor can detect occupancy as well as measure the temperature in the room. Maximum 6 sensors can be connected to the thermostat via bluetooth. This Installation Guide describes how to install the Sensor and pair it to a TrickleStar Wi-Fi Smart Thermostat.

Pairing the sensor Step 1: Remove Battery Insulator To power up the sensor, gently remove the sensor back cover to detach the cover from the clips. You will see an insulator on the battery “REMOVE BEFORE USE”. Lift the battery by pulling on the battery insulator and gently peel off the battery insulator. Insert the battery back into the sensor’s battery compartment. Reassemble the sensor back cover.
If the LED does not blink after the Sensor is powered up or after battery insertion or the Sensor exits Pairing mode after eight minutes, hold the Pairing Button for 2 seconds to re-initiate pairing to the thermostat. The sensor will enter Pairing mode again and broadcast itself for 8 minutes for thermostat scanning. LED will blink briefly in the mode. Fig 7-A Step 2: Add Occupancy Sensor to the system 1. Log in to your TrickleStar Portal account at: portal.tricklestar.
5. Press Next once your sensor LED is blinking to complete the pairing process. This will initiate a scan function and the Thermostat will scan for sensors in range. Sensors that are detected will be listed by their MAC addresses. Users can select from the list if there is more than one sensor to be paired and add the sensors. Note: It may take up to 30 seconds to detect and pair a new sensor. 6.
If pairing is successful, the LED will blink twice. Then, the Bluetooth indicator appears on the Thermostat display. Fig 9-A If pairing is unsuccessful or time-out after 8 minutes, the LED will stop blinking and the Sensor will go into standby mode. In Standby mode, the connection between the sensor and the thermostat is not set up. All the sensor circuits will be shut down to save power. Hold the Pairing Button for 2 seconds to initiate the Pairing mode again.
Mounting the Sensor on the wall Before you mount the Sensor on the wall, be sure to check that: • The sensor is connected to the Thermostat. • The sensor is mounted away from direct heating or cooling sources, such as a fireplace or an air ventilator. Attach the double-sided adhesive to the Sensor. Then, mount the Sensor at a height of approximately 5 ft. (1.5 m) on the wall. 5 ft. (1.
Placing the Sensor on a flat surface Before you place the Sensor on a flat surface, be sure to check that: • The sensor is connected to the Thermostat. • The sensor is placed on an even surface and at a safe location. • The sensor is facing the direction which you want to detect occupancy. Attach the stand to the Sensor. Then, place the Sensor on a flat surface.
Ready for use Normal mode The Occupancy Sensor is now ready for use. In Normal mode, the connection between the sensor and the thermostat is set up. The sensor will automatically update the Connection Status, Room Temperature, Occupancy State and Sensor Battery Level in the Tricklestar Portal and Tricklestar App. You can enable or disable the sensor detection LED operation in Normal mode through the TrickleStar Portal Sensor settings (Occupancy Detection LED Enabled).
Occupancy Detection The occupancy sensor is equipped with an occupancy detection function. It uses PIR sensor to detect the infrared signal of moving bodies. You can also enable or disable the occupancy detection function for each sensor individually through the Portal. You can adjust the Absence Detection Sensitivity and Occupancy Detection Sensitivity, and enable or disable the Occupancy Detection feature of the thermostat.
Changing Occupancy Detection settings on the Portal 2 1 Fig 13-A 3 14 Fig 13-B
Occupancy detection algorithm The thermostat changes the Mode automatically based on the received occupancy states from the sensors: If the Mode is “Home” You can set the Absence Detection Sensitivity as shown in Fig 13-B (Thermostat Sensor Settings).
Fig 16-A Fig 16-B 16
If the Mode is “Away” You can set the Occupancy Detection Sensitivity as shown in Fig 13-B (Thermostat Sensor Settings).
If the Mode is “Sleep” The thermostat will not change the Mode. To cancel the Mode change Press jog dial for 3 seconds to return to the Current Schedule.

Replacing the battery There is no low battery indication on the sensor. The Portal or App will send notification to remind you to change the sensor battery when the battery voltage drops to warning level (2.6 V) or critical level (2.3 V). When the voltage drops to Battery critical level or below, normal operation of the sensor cannot be guaranteed. Remove the Battery Cover and replace the battery in the battery compartment. Put back the Battery Cover.
Troubleshooting Symptom Solution The Occupancy Sensor does not pair with the TrickleStar Wi-Fi Smart Thermostat • Check that the battery insulator “REMOVE BEFORE USE” has been peeled off completely from the sensor battery and the sensor LED is flashing continuously. • Check if the Sensor is within the connection range of 98 ft. • If the sensor LED does not flash, hold the Pairing Button for 2 seconds to initiate pairing to the Thermostat.
