This Installation Guide describes how to install the Sensor and pair it to a TrickleStar Wi-Fi Smart Thermostat. If you have any inquiries about TrickleStar products or need technical support, visit our website for tutorials, videos and Frequently Asked Questions (FAQ).
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 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.
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.
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.
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.

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). When the occupancy sensor detects no movement within the Absence Detection Sensitivity time set, the Mode will automatically change to “Away (set by sensor)”...
Page 17
If the Mode is “Away” You can set the Occupancy Detection Sensitivity as shown in the illustration above (Thermostat Sensor Settings). When the occupancy sensor detects a movement within the Occupancy Detection Sensitivity time set, the Mode will automatically change to “Home (set by sensor)” and follow your preset Home Mode setting as shown below:...

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.
