• The maximum total current of the devices connected directly to the control module must not exceed 16 A, and the load power must not exceed 3500 W.
• Our thermostats can be used to control warm water floors and other indoor heating systems.
• If a thermostat is installed to control water heating systems, then a normally closed thermostatic head is connected to terminals 3 and 4 (load) according to the User Manual / Technical Certificate of the device.
• In case of non-standard application of the thermostat, its output relay is used as an ON/OFF control.
  Namely: when the temperature drops below the set value, the relay on the thermostat switches and generates a 220V AC voltage control signal at terminals 3 and 4. When the temperature rises above the setting, the voltage at terminals 3 and 4 disappears.
• The remote sensor of the thermostat can be installed both in the room to measure the air temperature, and directly on the return flow pipe of the heat carrier. The remote and built-in sensors can be used in parallel or separately, choosing the required one.

- a thermostatic head of normally closed type

From December 1, 2019, some thermostats may hang-up after connecting to the cloud. In this case, an incorrect indication may be displayed on the screen (for example, a symbol on a symbol). In this case, it is necessary to de-energize the device (turn OFF the circuit breaker on the switchboard) for 3-5 minutes and turn it ON again (turning ON the circuit breaker in advance.
After such a "restart" the device will operate normally.

• If the device has been added to the application, but after connecting and waiting, the information "Module not found in the network" is displayed, first of all, you need to make sure that the device is connected to the Wi-Fi network (the corresponding indication is provided in the User Manual), and that the distributing device (router / access point) has an Internet connection (sites can be opened).

If the above conditions are met, we proceed to check the device:

1. You will need a device on which the connection via the SST Cloud App will be established (for example, smartphone 1) and a device with Internet access, which will act as an access point (for example, another smartphone 2).
2. You can find instructions on how to run a smartphone in the access point mode in its User Manual or on YouTube. The requirements for the distributed network are as described above.
3. Before you proceed, it is recommended to check whether there is an Internet connection on the smartphone 1 connected to the smartphone 2 (which acts as a router).
4. Reset the thermostat according to the instructions (presented below, in the "Networking. Troubleshooting" section).
5. Connect the device according to the instructions for the standard procedure (in the home ownership settings, indicate the parameters of the network that is distributed by smartphone 2).

• If the device is working properly, then after a while it will be available for remote control, the message "Module is not found in the network" will not be displayed.
• In this case, refer to the section "Networking. Troubleshooting".
• The most common reason is the closed ports 6350, 1883, 8883. On some operators' equipment (Router or Access Point) and / or when configuring this equipment by the provider (operator), the port settings may be changed.
• If the ports are already open, then you need to perform their forced forwarding.
  
• In the event that the device still does not connect to the Internet, does not update, and after waiting, the application displays the message " Module is not found in the network ", it is recommended to additionally make sure that the network parameters are set correctly, all the above steps for setting up and connecting performed properly.

This can happen when the Internet speed is low - the list of devices is not loaded immediately. You can check the speed at www.speedtest.net Check the health of your WiFi router. If the internet speed remains too slow, contact your provider.

• Before applying the new network / router parameters, you should change the settings of your WiFi network in the home ownership settings or add a new WiFi network in the device settings and switch the devices to the new WiFi network (at the time of switching, the devices must be connected to the existing / old network / router, otherwise you need to reconnect to the cloud in AP mode).

In the SST Cloud App, you must perform the following steps:
1. Connect on the device (smartphone / tablet, etc.) to a new router / changed WiFi network
2. Open the SST Cloud App and select the home ownership in which the router / WiFi network has changed. If there is only one home ownership, then it opens immediately, by default.
3. Press the "Settings" icon in the upper right corner
4. Select the "WiFi network setup" item
5.1. In the upper right corner, opposite the name of the already installed WiFi network, click the "Settings" icon and edit the changed parameters
5.2. Select the "Add WiFi network and enter new WiFi network data" item

• Important! The network name and password must not contain spaces, punctuation marks and Cyrillic characters. (These data are set when configuring the router).

Q: I can't establish WiFi network connection with the device
A: Check if the entered password is correct to connect to the WiFi network of the device. It is also possible that another nearby smartphone or tablet has automatically connected to the device. If after checking the problem is not resolved, try restarting your device. You can also contact the support service.
Q: The device does not find the network when operating in the AP mode
A: Make sure the device is in the AP mode. If it is so, switch the thermostat to the SA mode and then back to the AP. Or restart your device. If the problem persists, please contact the support service.
Q: The device does not connect to the WiFi network after receiving the WiFi settings
A: Make sure that the network name and password have been entered correctly (you can check this in the home ownership settings "WiFi network settings"). If the WiFi settings were incorrect, you need to delete the network and add the device again. Check if devices have access to the Internet (see Checking open outgoing ports). You can also reset the device settings (see "How do I reset all module settings to their default values?"). You can also contact the support service.
Q: The device does not appear on the network after being added
A: Make sure the device is turned ON and check your internet connection. It may take a few minutes for the settings to be applied after adding the device. If the device remains to be inactive, try removing it and adding it again. You can also contact the support service.
Q: There are problems with the device WiFi networking
A: Make sure your WiFi router is turned ON, working properly, and the device is within its coverage. Check if the WiFi settings are correct (you can check this in the home ownership settings "WiFi network settings"). Try restarting your device. You can also reset device settings (see "How do I reset all module settings to their default values?"). If the problem persists, please contact the support service.
