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: Pull the plastic tag To power up the Sensor, pull out the plastic tag from the Sensor gently. Plastic tag When the Sensor is powered up, it enters Pairing mode automatically. The LED starts blinking and continues blinking up to eight minutes.
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. Step 2: Add Occupancy Sensor to the system 1.

Step 2: Add Occupancy Sensor to the system 1. Log in to your TrickleStar Portal account at: portal.tricklestar.com You can also use the QR code here. 2. At Dashboard screen, select Devices, then click on your Thermostat Name to enter Thermostat page. 3. Select Sensors on the left panel, then click on “+” to add a new sensor. 4. Enter the name for your sensor. 5. Press Next once your sensor LED is blinking to complete the pairing process.
If pairing is successful, the LED will blink twice. Then, the Bluetooth indicator appears on the Thermostat display. 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).
Occupancy Detection The occupancy sensor is equipped with an occupancy detection function. It uses PIR sensor to detect the infrared signal of moving human bodies. You can also enable or disable the occupancy detection function for each sensor individually through the Portal or App. When disabled, the individual sensor detection circuit will be shut off and the occupancy states will not be available.
Changing Occupancy Detection settings on the Portal 2 1 3 14
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 the illustration above (Thermostat Sensor Settings).
If the Mode is “Away” You can set the Occupancy Detection Sensitivity as shown in the illustration above (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 Schedule Mode.

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 plastic tag has been pulled out fully from the Sensor and the sensor LED is flashing continuosly. • Check if the Sensor is within the Radio Frequency (RF) range of 98 ft. • If the sensor LED does not flash, hold the Pairing Button for 2 seconds to initiate pairing to the Thermostat.
