TELETHINGS THERMOSTAT LORAWAN USER MANUAL

BASIC INFORMATION / PRODUCT DESCRIPTION

Wireless thermostats and Receiving switch modules are devices intended for heating system management. Receiving switch module is directly connected with the heating system, and based on the information given from the server, the module performs heating system regulation by activating or deactivating the relay.

Advantages and main characteristics of the device are:

A wireless thermostat is a small energy consumer
A wireless thermostat can change the location (room) of the reading temperature
The wireless thermostat shows the current temperature and set the temperature on display
Wireless thermostat shows an indicator of communication with the server
Devices can communicate on long distances
Simple device installation
Simple device handling

Button „UP“, increases the set temperature by 1°C
Button „DOWN“, and decreases the set temperature by 1°C

The device can be turned ON / OFF by pressing and holding the „Power“ button for 1 second. If the device was turned OFF, on the display it will be shown as in the picture (Figure 3. – left), and while holding the button for a 1-second display will turn ON. While turning it on, the display will look like the picture (Figure 3. – right)

Pressing and holding the button „UP“ or „DOWN“, the device enters in the menu for setting the temperature. Respectively, pressing the button „UP“ set temperature increases by 1°C and decreases by 1°C if the button „DOWN“ is pressed. In the picture (Figure 4.) graphical representation of setting the temperature is shown.
The radio icon is an indicator of successful communication between applications on the server and the device. The battery icon is an indicator of the device’s low battery. When the battery icon appears, batteries must be changed as soon as possible.
The transfer icon is an indicator of communication between the application on the server and the device. While the transfer is in progress buttons are unable to use. Press and hold the button to faster device response.

LORA JOIN THE PROCEDURE FOR THE THERMOSTAT

To be able to communicate with the server and receive messages from the server, LoRaWAN devices must complete the JOIN procedure with the server. The JOIN procedure initiates automatically while the device is being turned on. Upon sending JOIN request to the server, the display will look like the picture (Figure 6. – left). If the device fails to JOIN with the server, ER letters will appear on display, meaning there was an error while executing the JOIN procedure (Figure 6. – middle). If the device successfully finished the JOIN procedure, OK letters will appear on display (Figure 6. – right).
After the device has successfully finished the JOIN procedure, it can send and receive messages from the server.

LORA JOIN PROCEDURE FOR RECEIVING SWITCH MODULE

After the device is turned on, a red LED will turn on. After ten seconds, the JOIN procedure with the server will initiate. If the JOIN procedure has been successful, both red and green LEDs will blink three times and then the red LED will stay turned ON while the green one will turn off. Red LED is an indicator of a successful JOIN procedure and if it’s on, it means that the procedure has finished successfully. If the red LED continues blinking, it means that JOIN procedure has failed. Green LED is an indicator of relay state and if it’s on, it means that the relay is turned on.
After the device has successfully finished the JOIN procedure, it can send and receive messages from the server.

RECOMMENDATION FOR USE

Due to the relevance and validity of measurement and regulation, wireless thermostats should not be installed near heat sources, such as radiators, furnaces, refrigerators, and other objects which can emit heat in their immediate vicinity. Also, for the same reason, Home Sensor should not be installed near windows or entrance doors. It’s not recommended to install devices (Home Sensor and Control Box) on unstable surfaces or surfaces
which are exposed to vibrations, due to a possible fall of the device and physical damage. Keep devices as far as possible from the impact of high humidity and liquid sources due to possible damage to the device’s electronic components. Keep the device out of reach of children.

SPECIFICATION

WIRELESS THERMOSTAT

Description	Device for measuring, setting, and reporting the temperatures
Measuring the temperature	0°C – 60°C, with a 1°C step
Setting the temperature	5°C – 35°C, with 1°C step using the device, or a 0,5

°C step using the application
Set temperature regulation| +/-0,5°C
Server communication| Mandatory sending current temperature to the server after a desired period of time (min. 3 minutes, max. 240 minutes) which user can set on server (if the user sets 0 for period of communication, it disables mandatory sending option), or while room temperature was changed by 0,5°C or after the new temperature has been set. Pressing the buttons UP or DOWN, the set temperature is selected and sent.

DEVICE INSTALLATION

Installation of the device receiving switch module should be done by a service engineer or a licensed person.
Control Box installation directions:

Turn off the power supply on the heating system (due to protection against possible electric shock)
Twist the antenna (868MHz) on Control Box; on the connector designed for the antenna (Figure 6.)
Connect heating system and receiving switch module with voltage-free (dry) contact/Connect heating system on electronically controlled switch (Relay) as shown in the picture (Figure 5.)
Connect power supply on receiving switch module on AC power supply. The scheme of power supply is shown in the pictures (Figure 5. and Figure 7.), if possible use the power source for receiving the switch module from the heating system.
Turn the heating system’s power supply on.

Wireless thermostat preparation guide:

Disassemble Home Sensor (Figure 8.)
Insert the batteries in the Home Sensor device (Figure 9.)
Assemble Home Sensor in original condition

Changing batteries depending on the special installation, it is recommended to use alkaline AAA batteries. If the batteries over time become empty, an indicator of empty batteries will be shown on the display and the batteries should be replaced following these steps:

Remove the housing of the thermostat by gently withdrawing it from the base.
Take old batteries out and replace them with new ones. 3. Be sure to set symbols (+) and (-) correctly.

NOTE: Replacement of batteries is recommended once a year or if the thermostat will be unsupervised for a long time.
