LED indications in the receiver
The status of the receiver is indicated by two LEDs. These are LEDs with the following colors:
- red (upper one),
- green (upper one),
- blue (upper one),
- pink (upper one),
- orange (lower one).
A detailed explanation of the meaning of the LEDs
| DESCRIPTION | |
| The red LED flashes | The red LED diode flashes – Receiver and thermostat are prepared for installation in the app.
LED always flashes red: – immediately after connecting the receiver to the power supply, if the thermostat is not added to the app – after running the parameter“APP”->YES (installer parameters) – after removing the thermostat from the app (device automatically entered pairing mode) |
| The red LED steady | The red LED is steady – has not been installed in the app and it is working in Offline mode. It means also the app pairing mode timed out (pairing with the app must be done
within 10 minutes after enabling pairing mode). |
| The green LED is solid | The receiver is connected to a router but there is no connection to the Internet (the router is offline) |
| The green LED flashes | The receiver lost connection with a router (the router is off) |
| The blue LED is solid | The receiver is connected to a router that has Internet access (the router is online) |
|
The blue LED flashes |
The receiver was paired but lost communication with the thermostat due to range or low battery in the thermostat. When the receiver loses communication
with the thermostat, it starts flashing after 15 minutes. |
|
The orange LED is a solid |
In automatic mode, the receiver receives a heating/cooling signal from the thermostat or
the receiver was started in manual mode (left switch ON, right switch MANUAL) |
| The orange LED flashes | The receiver is in the pairing mode and is looking for a signal from the thermostat (then you must activate the“SYNC” parameter in the thermostat). |
| The orange LED is off |
The receiver does not send a heating/cooling signal. |
| The pink LED is on | The update process started. To increase the chance of success of the update – immediately after the pink diode appears, click any thermostat’s button to turn on backlight |

Installation of the thermostat in the app
- Make sure your router is within range of your smartphone.
- Make sure you are connected to the Internet. This will reduce the pairing time of the device. Use only Wi-Fi 2,4GHz network.
STEP 1 – DOWNLOAD ENGO SMART APP
- Download the ENGO Smart app from Google Play or Apple App Store and install it on your smartphone.
STEP 2 – REGISTER THE NEW ACCOUNT
- To register a new account, please follow the steps below:
STEP 3 – CONNECT THE THERMOSTAT TO WI-FI
- After installing the app and creating an account:
- On your mobile device, make sure the ENGO Smart has access to permissions (Location, Bluetooth, Nearby devices). Then turn on Bluetooth and Location. Connect to the 2.4GHz Wi-Fi network to which you want to assign the device.
- Connect the receiver to the power supply. When first powered up, the red LED will start flashing, which means that devices are ready to be added to the application. Go to step 7 (adding devices in the app). If the red LED on the receiver is not flashing, proceed with the next steps.
Pairing process with the receiver
PLEASE NOTE! THE THERMOSTAT IS ALREADY PAIRED WITH THE RECEIVER
If you want to repair the receiver and thermostat with each other and then add it to the application, make sure that the receiver is disconnected from the power supply, and the switches on it are in the ON and AUTO positions. Then connect the receiver to the power supply and wait a few seconds. Next, move the left switch to the OFF position and back to the ON position with a quick motion. The orange LED will start blinking, which will confirm that the receiver has entered the pairing mode.
- The thermostat started to send a signal to find the receiver (the symbol of the blinking antenna) and started the countdown with the number 10 (min). The pairing process may take up to 10 minutes.
- When the orange LED stops blinking, the devices have been paired on a new frequency.
- The thermostat will display the message „good”, which means that the devices are successfully paired with each other. The thermostat will return to the next APP parameter in the service menu (adding to the application).
- You can skip this step and return to the main menu by clicking the (OK) button a few times.
WARNING! If the orange LED on the receiver has not stopped blinking after 10 minutes, repeat the pairing process taking into account the distance between devices, obstacles, and interference.
