SETUP OF REMOTE TEMPERATURE SENSOR

A wireless temperature sensor is provided to monitor the ambient temperature from any remote location. It needs to be paired with the heater and will transmit real-time temperature to the heater for highly accurate room temperature control.
Sensor Placement
Important : Avoid areas that can have temperature extremes, making the sensor think the room is cooler or warmer than it actually is. Don’t install the sensor near doors that could let in drafts, on exterior walls, or near windows in direct sunlight.
Product Overview ECO2S REMOTE SENSOR:
IMPORTANT: Ine remote sensor must be paired to the heater prior to use. If the display shows 15″ the sensor has not been paired successfully.
Repeat Pairing Process
PX-ECO Technical Specifications:
Protocol: Wireless 2.4G Transmit Distance: 98′ Working Voltage: DC 3V (battery); Detecting Temperature: 0° to 99°F
Pairing and Installation Guide
Since it is possible that more than one heater/sensor would be used in a home, you must first pair the remote sensor to a specific heater. Each remote sensor has a unique ID number, which will be used in the pairing process. When installing the remote sensor first time, users need to pair the remote sensor with PX heater, so the heater can learn and save the remote sensor’s ID.

Step 1: First, power off the remote sensor (remove the battery or unplug the adapter).
Step 2: On the Heater’s Display Press and button at the same time for 5 seconds. The LED display will flash “id”.
Step 3: Release the buttons, put the remote sensor within 3 feet of the heater, and power on the remote sensor again. The green LED light in the remote sensor will flash, and PX the controller display indicator lights will illuminate (LED tubes show 88) for 1 second and then turn off. This means the remote sensor and the controller have paired with each other successfully.
NOTE : If the PX display flashes “id” for 20 seconds and then turns off, it means that the heater failed to pair with the remote sensor and has exited the Pair mode. Repeat the above steps to pair the remote sensor.
Step 4: After pairing the remote sensor successfully, put the sensor in the room where you want to detect temperature. The PX heater display will now display the temperature from the remote sensor.
Installing Batteries
Open the battery cover and insert 2pcs AM batteries, and reinstall the battery cover. Low Battery Indicator
When batteries are low, “BA” will flash on the PX heater display to indicate batteries should be replaced. Note: If batteries fail, the PX is designed to revert back to the onboard temperature sensor for temperature control until the batteries are replaced in the remote sensor.
Mounting The Remote Sensor
The sensor can be placed on any flat surface or can be fixed to the wall with the mounting bracket. Mounting Bracket Install: Select the location for the sensor on the wall,. Secure the bracket with 2 appropriate anchors and screws. Insert the remote sensor into the bracket. Low Signal Indicator
When the sensor is not paired with the heater or if the signal is being blocked. the display flashes “LS”. After 10 minutes, the controller will automatically switch to work with the onboard temperature sensor, but the display will continue to flash “LS” until the signal is restored.

1. Following the Pairing process above successfully pair the sensor.
2. Move the Sensor closer to the heater or away from metal objects that might block the signal.
