ENGO CONTROLS E25-BATW Zig Bee 868MHz Smart Thermostat

INTRODUCTION

Internet controlled thermostat with surface-mounted design (battery-powered 2xAA). The product is based on a ZigBee/868MHz wireless communication technology. It is designed for radiator or floor heating. It works with electronic wireless heads. It can control up to 6 radiator heads in one room. Thermostat sends temperature measurements to the heads for better control accuracy – it will ensure also comfort and savings. A unique feature of this thermostat is the ability to control devices WIRELESSLY (ENGO binding function). The “ENGO binding” function makes thermostat to communicate directly with receivers, e.g. a wireless control box or relay module (devices with “BIND” function). ZigBee binding can only be performed using the Internet gateway (sold separately). If thermostat is used with an internet gateway connected to the internet, it has the ability to be controlled wirelessly via the ENGO Smart mobile app. When added to the mobile app, thermostat gets additional functions, e.g. time schedules or push notifications. Thermostat has also a key lock function, possibility of setting minimum and maximum temperature setpoint limits and the ability to operate in heating or cooling mode.

Installation 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.
STEP 1 – DOWNLOAD ENGO SMART APP

STEP 2 – REGISTER THE NEW ACCOUNT
To register a new account, please follow the steps below:

1. Click „Register” to create new account.

3. Enter the verification code received in the email. Remember that you only have 60 seconds to enter the code!
4. Then set the login password.

STEP 3 – CONNECT THE THERMOSTAT TO ZigBee

1. Make sure ZigBee Gateway has been added to the Engo Smart app. Press and hold the – and + buttons on the thermostat until the display shows „PA”. Then release the keys. The pairing mode will be started up.
2. Thermostat counts the time back (180s).
3. Enter the gateway interface.
4. In Zigbee devices list” go Add devices”.
5. Wait for the message “End” to appear on the thermostat screen.
6. Name the device
7. The thermostat has been installed and displays the main interface.
8. On the controller screen globe icon appeared stating that he has been added to the ZigBee network.

Synchronization with head
An internet gateway is not mandatory to synchronize thermostat with head. Make sure head is installed and adapted to valve insert (see head manual). If thermostat is connected to a wireless control box or relay module, synchronization with head cannot be activated.

1. After successful adaptation process, press&hold head button for 3 seconds. The LED will start flashing blue.
2. Hold simultaneously – and + buttons on thermostat until the “SY” function appears.
3. Release buttons, SYNC function will be active (synchronization with head).
4. After successful synchronization, LED diode will indicate blue light for 10 seconds.
5. Thermostat will indicate how many heads are synchronized.
6. “END” message will appear after successful synchronization.
7. The devices are synchronized and ready to work.

ATTENTION: The synchronization should be performed for each head separately. One thermostat can control up to 6 heads within one room.

Binding thermostat with the wireless control box
Make sure that the control box and thermostat are in the same ZigBee network (they are added to the same gateway) and the POWER LED lights up blue.

1. In order to correctly link thermostat with the control box, first select the zone in the control box with the SELECT button (1) (zone which you want to link with thermostat). The LED (2) will flash 3 times for the selected zone. Confirm your selection by clicking PAIR button (2). The LED (2) will flash green with the previously selected zone – binding process has started, it is active for 10 minutes and during this time you can link thermostat with the selected zone.
   To properly link thermostat with the module/relay first click quickly the button on the device 5 times.
   The LED diode will start flashing slowly on red, which means the device is in binding mode.

2. On the thermostat, hold – and + buttons until the “bind” message appears.

3. Release the keys, binding function process of linking thermostat is active.

4. The “binding” process takes up to 300 seconds.

5. After successfull binding operation End message will be displayed.

6. Both devices have been successfully linked. Thermostat displays the main screen, icon appeared on the screen indicating connection with the receiver.

ATTENTION

• If the binding process fails, it must be repeated taking into account the distances between devices, obstacles and local radio signal interferences.
• When the thermostat is binded with the zone, the zone will turn off after 50 minutes, if the communication between the devices is lost.

Remember
Radio range can be increased by Engo ZigBee repeaters.
