Receiver

Receiver’s switches description:
LEFT SWITCH

1. Receiver ON
2. Receiver OFF
   RIGHT SWITCH
3. MANUAL – Receiver works in manual mode (according to the left switch)
4. AUTO – Receiver works in AUTO mode (according to the thermostat’s command)

LED indications in the receiver
The status of the receiver is indicated by two LEDs. These are LEDs with the following colors:

A detailed explanation of the meaning of the LEDs can be found in the table below:

	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, Ef the thermostat is not added to the app – after running the parameter”APP”-> YES (installer parameters) – after removing thermostat from the app (device automatically entered pairing mode)
The red LED steady	The red LED diode is steady – E20i VVi-Fi has not been installed in the app and it is working in Offline mode. It means also app pairing mode timed out (pairing with app must bedone within 10 minutesafter enabling pairing mode).
The green LED is solid	The receiver is connected to a router but there is no connection to Internet (router is offline)
The green LED flashes	The receiver lost connection with a router (router is off)
The blue LED is solid	The receiver is connected to a router that has Internet access (router is online)
The blue LED flashes	The receiver was paired but lost communication with the thermostat due to out of range or low battery in the thermostat. When receiver lost communication with thermostat it starts flashing after 15 minutes.
The or LED is solid	In automatic mode, the receiver received 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 fora signal from the thermostat (then you must activate the “SYNC” parameter in the thermostat).
The °ran( LED is off	The receiver does not send a heating / cooling signal.
The pink LED is on	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 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:

1. 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 2.4GHz WFi network to which you want to assign the device.
2. 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 5 (adding devices in the app). If the red LED on the receiver is not flashing, proceed with the next steps.
3. Press and hold the – & + buttons for approx. 5 seconds until the display shows „PA”. Then release the keys.
   The pairing mode will start.
4. The Thermostat counts the time back (180s).
5. In the app, select: „Add Device”.
6. After finding the thermostat, go „Add”.
7. Select the Wi-Fi network in which the thermostat will operate and enter the password of this network.
8. Wait for the app to configure the thermostat with the selected Wi-Fi network.
9. Go „DONE”.
10. The thermostat has been installed and displays the main interface.
11. When the blue LED on the receiver will light up, it means the device has been correctly added to the application and is now connected to the Internet.

Pairing process with the receiver
PLEASE NOTE!
THERMOSTAT IS ALREADY PAIRED WITH THE RECEIVER!

If you want to re-pair 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.

Press and hold the – & + buttons for approx. 5 seconds until the display shows „SY”. Then release the keys.

The thermostat started to send a signal to find the receiver and started the countdown with the number 300 (sec). The pairing process may take up to 300 seconds.

When the orange LED stops blinking, the devices have been paired on a new frequency.

After successfull pairing operation ” End” message will be displayed.
Thermostat displays the main screen, icon ”” .

PLEASE NOTE!
If the devices remain unpaired after 10 minutes (e.g. no antenna icon on the controller, the receiver does not respond to the heating signal from the controller), the pairing process must be repeated, taking into account the distances between the devices, obstacles and interference.

Installer settings
To enter installer parameters press and hold button for 3 seconds.

Use – or + button to move between parameters. Enter the parameter by . Edit the parameter using – or +. Confirm the new parameter value with the button.
