EREL1ZB12A
Smart Relay ZigBee, 12A

Quick Guide

Introduction

The product is designed for intelligent control devices that need to be controlled over voltage-free signal. The voltagefree output makes also possible to control devices which require 230V voltage.  The size of the module allows to place it in a flushmounted installation box. It can be used as a boiler control relay for heating system („normally open” output logic). It works according to programmed  schedules or scenarios (e.g. work dependent on the actions of others system elements, such as a window/door opening sensor or temperature controller). EREL1ZB12A can be controlled remotely (via smartphone and Engo Smart/Tuya app) or locally using a bistable/monostable switch.

The relay is equipped with the ENGO binding function, to connect it wirelessly witch selected thermostats (e.g. EONE) in Online or Offline modes.

WARNING:
This product must be used together with a EGATEZB ZigBee gateway (purchased separately).

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
Download the ENGO Smart app from Google Play or Apple App Store and install it on your smartphone.

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

STEP 3 – CONNECT THE RELAY TO ZigBee network
After installing the application and creating an account, follow these steps:

Make sure ZigBee gateway has been added to the Engo Smart app.	Make sure the relay is connected to the power supply. The LED should flash quickly on red. If not, hold down the button for about 8 seconds. The relay will enter pairing mode.
Enter the gateway interface.	In „Zigbee devices list” go „Add devices”.
Wait until the application finds the device and click ”Done”.	The relay has been installed and displays the main interface.

BINDING thermostat with the module/relay

Make sure that the relay and thermostat are in the same ZigBee network (they are added to the same gateway EGATEZB).

To properly bind thermostat with the relay first click quickly the button on the device 5 times. The LED diode will start flashing slowly on red, which means the device will enable binding mode.

On the EONE thermostat, hold and buttons until the „bind” message appears.

Release the keys, binding function (process of linking thermostat with control box) is active.

The „binding” process takes up to 300 seconds.

After successfull binding operation „End” message will be displayed. LED on the module will stop flashing.

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.

Remember:
Radio range can be increased by Engo ZigBee repeaters.

Factory reset

To reset the device, press and hold the function button for approx. 8 seconds until the LED flashes red. The relay will be removed from the ZigBee network and gateway, then goes into pairing mode. Now it’s possible to add the relay again (see STEP 3 –  CONNECT THE RELAY TO ZigBee network).
