Immergas SMARTECH PLUS Instructions And Warnings page 3

N.B: the selection described above is temporary and will be lost when the batteries of the Chrono-thermostat are removed. In this case, the default setting value ('IMG BUS' generator) is restored.
2. SAFETY MODE
SMARTECH PLUS
The Smartech Plus system activates the 'Safety mode' if Bluetooth communication fails between Gateway and Chrono-thermostat.
Basically this could occur if the two devices are further away than the maximum allowed distance for the specific installation (in this case the message ' Disconnected' appears on the Chrono-thermostat display), or if the
Chrono-thermostat batteries are dead.
In 'Safety mode' the Gateway controls activation of the generator in heating with a water temperature of 20°C, so as to protect the heating system and the involved environments against freezing.
N.B.: this function is only activated with the system OFF or in 'Winter' mode, and is not active if the gener-ator is controlled by the Gateway only via the operation request contact (in this case, if communication with
the Chrono-thermostat fails, the Gateway removes the operation request and any system antifreeze protections are fully controlled by the generator).

Indicates that the Gateway is powered properly. This LED must always be on steady and green.
It signals the Bluetooth connection of the Gateway with the Smartech Plus chrono-thermostat:
• 1 blink every 4 seconds: it means that communication between the Gateway and the Chrono-thermostat is established correctly;
• 5 blinks per second: it means that the Gateway is trying to connect to the chrono-thermostat, if this warning is frequent, try to bring the Gateway
closer to the chrono-thermostat or vice versa. .
It is a service Led managed separately from the Gateway, its operation is independent from any Gateway status.
Signals the connection to the home Wi-Fi network and the Cloud of the chrono-ther-mostat:
• Off: it means that the Gateway is not con-nected to any Wi-Fi network or no Account has been connected to this Gateway, the chrono-thermostat works regularly
even without a Wi-Fi connection, through the BLE connection;
• 1 blink per second: it means that the Gate-way is connecting to the Wi-Fi network or associated Account, if this warning persists check that the Wi-Fi network is active
and verify that you have entered the correct password in the Gateway;
• Steady on: it means that the Gateway is connected to the Wi-Fi network and Cloud and is working properly..
