MAIN UNIT DESCRIPTION

RECEIVER DESCRIPTION

FIRST USE WARNINGS AND INSTRUCTIONS

The system comes with main unit and receiver paired from the factory. Before use, you only need to pair the receiver unit with the nearby Wireless Router.
At first start, the thermostat/receiver unit signals by LED 1 = “ slow blinks” which means it is necessary to connect the unit to the wireless router with Internet access.
Insert 2 AAA alkaline batteries (not included) into the main unit and turn it on by pressing the ON/OFF button. The settings appear as shown in above description.
Connect the receiver unit to a 230 VAC power supply (only qualified personnel). Make sure it works properly by testing/checking the LED status and turning unit On/Off by the dedicated button.

PAIRING THERMOSTAT WITH MOBILE APP AND WIRELESS INTERNET ROUTER

Connect your smartphone to the 2.4 GHz wireless Internet router nearby. Activate GPS Location on your smartphone. For a quick setup make sure both phone, thermostat receiver and wireless router are as close as possible (1-3 m).

WARNING: Check and make sure that you have a 2.4 GHz Wireless network available and that you have connected the phone to it. The new generation routers and phones are also equipped with the 5 GHz wireless network activated and the devices connect automatically on this frequency. The thermostat cannot be connected to the 5 GHz wireless network because it only works on the 2.4 GHz wireless frequency. To configure the router and the 2.4 GHz wireless network, call a specialist.

Download the “TuyaSmart” app from Google Play or App Store, andd install and register a new account: Press the “Sign Up“ button and follow on-screen instructions.
Add device by pressing the + button in the top right corner.
Press “All Devices” and access the Small Home Appliances category.
Find “Thermostat” or “Heater” from list and select. Follow the on-screen steps, check the name of the Wifi network and enter the password of the Wifi network with internet access to which the phone is also connected. If the wireless network does not appear automatically, check if you have GPS Location enabled and if you have your phone connected to a 2.4 GHz wireless network. Restart procedure.
Long press the pairing button on the receiver to enter Wifi pairing mode until LED 1 blinks quickly. (before this, LED 1 blinks slow, sign that thermostat is not paired with wifi internet router)
Tap the “Confirm indicator flash blink” on your phone.
Wait a few moments until pairing is complete. The LED 1 on the receiver will stop blinking and turn off. At this point, connection to the Internet via Wireless router is successful, and the Thermostat icon will appear in Smartphone app.
If the LED continues to blink slowly, the connection failed, try again from step 1.

FIRST USAGE OF THERMOSTAT

With main unit screen ON, change the temperature higher or smaller the measured temperature on screen.
In a maximum 90 seconds, the main unit sends a command to the receiver unit, which confirms by turning on/off LED 1, and by a “click”, that is heard from the inside relay.
From the TuyaSmart app (make sure the device appears online after configuring internet pairing) tap on the device to access it. Using the “+” and “-” buttons, change the temperature bigger or smaller the measured temperature from the screen.
In 90 seconds maximum the app sends a command through the internet to the thermostat receiver unit, which confirms by turning on/off LED 1, and with a “click” sound inside relay. The temperature will change on the main unit screen.
If there is no change after 90 – 180 seconds (2 minutes), check again if you have changed the temperature to bigger/smaller than the current temperature displayed and check if the device is online.

PAIR MAIN UNIT WITH RECEIVER UNIT

Perform this procedure only if absolutely necessary and find that: if after 10 minutes of successful pairing with the wireless router, the device appears Offline in the application/the signal icon is missing from the screen/LED 1 on the receiver is off and the units do not communicate with each other.

Press and hold the pairing button on the receiver until LED 1 flash quickly.
With main unit screen closed (press the On/Off button), long-press the M button on the main unit until a 4-digit code and three more symbols appear on the screen. Press the “up arrow” button immediately for pairing.
LED 1 blink slowly; wait for a few moments until LED 1 stops flashing and closes. The signal icon flashes for a few moments after which it remains on the screen confirming that the pairing is completed.
Switch off and on the main unit, and test functions by changing temperature higher/lower than the actual temperature from the thermostat screen.

DELETE CLEAR ALL PAIRING

On the receiver unit press and hold both pairing and On/Off buttons for 5 seconds until LED1 and LED2 turn on. Release buttons.
Then LED 1 turns off, which means that all pairings have been cleared.

SIGNAL LOST OR WEAK

In case of loss/disconnection of the RF signal (between the receiver and the central unit) the signal icon on the screen will disappear.
When the receiver unit is disconnected from the Wireless, LED 1 will flash slowly.
Check and replace batteries if necessary.
Move units closer to each other and the WiFi router and check the status of the devices again.
If within a few minutes the operation does not return to normal, delete all pairing and perform the pairing procedures of the receiver with the main unit and after that of the receiver with a wireless router (with the mobile application) again.
