TS1921 Occupancy Sensor
Installation Guide

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.

Sensor Overview

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 peeling off the battery insulator.
Insert the battery back into the sensor’s battery compartment. Reassemble the sensor back cover.

When the Sensor is powered up, it enters Pairing mode automatically. The LED starts blinking and continues blinking for 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. Log in to your TrickleStar Portal account at: portal.tricklestar.com You can also use the QR code here.
   http://portal.tricklestar.com

2. On the Dashboard screen, select Devices, then click on your Thermostat Name to enter the Thermostat page.

3. Select Sensors on the left panel, then click on “+” to add a new sensor.

4. Enter the name of your sensor.

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. Once your sensor is successfully added, the Connection Status, Temperature, and Occupancy State will be “Not Used”. Wait for 1-2 minutes then Sensor Data will be auto-updated or you may click on the “Refresh Sensor Data” button to update the sensor readings.

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.
Note: If the sensor is previously registered, it will be added to the thermostat network automatically in Pairing mode. If disconnected, the sensor will change to Pairing mode automatically and try to reconnect with the thermostat. Users can also press the pairing button to restart the sensor in Pairing mode.

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.

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 in 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). This option also disables the sensor detection LED by default, where the sensor LED will not blink when it detects a movement. If the LED is enabled it will blink once when there is movement detected within the 30-second interval.

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. If disabled, regardless of any sensor output and individual sensor settings, the thermostat will ignore the occupancy status received and will not
automatically change the Mode. However, it will not shut off the sensor detection circuit and you can still check the occupancy states for each sensor through the Portal or App.
The occupancy detection feature is enabled if:
a) The Occupancy Detection Enabled is set to Yes at the Portal.
b) The Sensor Enabled of each individual sensor is set to Yes at the Portal.
c) The Sensor Status in the Portal is Connected.
d) The active Mode is Home or Away (not Sleep).
e) The Thermostat is on Schedule mode, not on Temporary/Permanent/Vacation Hold or when user has changed the Mode manually.

Changing Occupancy Detection settings on the Portal

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).
When the occupancy sensor detects no movement within the Absence Detection Sensitivity time set, the Mode will automatically change to “Away (set by the sensor)” and follow your preset Away Mode setting as shown below:

If the Mode is “Away”
You can set the Occupancy Detection Sensitivity as shown in Fig 13-B (Thermostat Sensor Settings). When the occupancy sensor detects a movement within the Occupancy Detection Sensitivity time set, the Mode will automatically change to “Home 1 (set by the sensor)” and follow your preset Home 1 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 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. The Sensor will automatically power up and reconnect to the TrickleStar Wi-Fi Smart Thermostat.

Troubleshooting

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.
When you have added the Occupancy Sensor but the Connection Status, Temperature, and Occupancy The state is “Not Used”| Wait for 1-2 minutes then Sensor Data will be auto-updated or you may click on the “Refresh Sensor Data” button to update the sensor readings.
