FOREWORD.

Smartech Plus is a Smart chrono-thermostat designed to guarantee ideal room temperature conditions at any time of the day and night for each individual day of the week. If connected to the Internet via home WiFi, this device is able to remotely control the air-conditioning system in a simple and efficient way directly from one’s smartphone. Smartech Plus consists of Smartech Plus Chrono-ther-mostat (hereinafter Chrono-thermostat) and Smartech Plus Gateway (hereinafter Gateway).

It can be installed in a few minutes: the Gateway is pow-ered at 230 Volt AC by the mains and must be connected to the generator via communication bus or operation request contact.
While the Chrono-thermostat, with independent battery power supply, does not require any electrical connection and is equipped with an e-ink technology display for displaying the main information such as room tempera-ture, operation mode, etc. The Chrono-thermostat can be positioned on its table base (supplied in the package), or it can be wall-mounted. Communication between Gateway and Chrono-thermo-stat is performed via Bluetooth connection, while between Gateway and Immergas Cloud via WiFi.

The system is completed by the “Smartech” application which can be downloaded from the iOS and/or Android Store and installed on the mobile device (smartphone). On completion of installation, the chrono-thermostat is already operational thanks to the pre-set program inside. Use of the dedicated app makes it extremely easy to program the Smartech Plus system and to completely control all the set values.

N.B.: before performing any electrical connection, make sure that all the involved appliances are disconnected from the mains.
N.B.: t he Gateway must only be powered by the power cable supplied as per standard with the product. Should the power cable be damaged, do not use the device and contact an authorised Immergas After-sales Centre.
N.B.: for correct installation prepare a dedicated power line for the connection of the Gateway according to the Standards in force regarding electrical systems. If this is not possible interference due to other electric cables could cause malfunctioning of the module itself.
The electrical connections of the Gateway must be car-ried out following the diagrams illustrated in chapter 4, or the instructions supplied in the Immergas generator installation manual.
If used coupled to a generator not manufactured by Immergas, the Gateway power cable must be connected to a 230Vac / 50Hz mains in compliance with standards in force regarding electrical installation, which anyhow must include a class III overvoltage category omnipolar disconnection device.

Wall-mounting of appliances.

• N.B.: make sure that the area of installation of the data reception/transmission module (Gateway) receives the signal of the home Wi-Fi network properly and the Chrono-thermostat Bluetooth.

• N.B.: the wall-mounted support installation is the same both for fixing the Gateway and the Chrono-thermostat.
  Gateway wall-mounting (Fig. 3): install the mount (2) fixing it to the wall with expansion plugs (1) and the supplied screws (3).

• N.B.: pay attention to correctly position the spirit level (10) downwards.
  After having wired the Gateway (4) as indicated in the connection diagrams illustrated in chapter 4, position the cable gland (7) in the specific slot (8). If additional cables were used to connect the IMGBus and/or ModBUS com- munication ports, break the pre-cuts (9) to allow these cables to come out of the Gateway enclosure.
  Apply the Gateway (4) to the mount (2) already fixed to the wall and secure it by tightening the two fixing screws all the way (5).

Chrono-thermostat wall-mounting (Fig. 4):
install the mount (2) fixing it to the wall with expansion plugs (1) and the supplied screws (3).

• N.B.: pay attention to correctly position the spirit level (5) downwards.

Release the body of the Chrono-thermostat (4) from the table base, then insert the 2 LR03 (AAA) batteries supplied in the specific compartment (Fig. 5), then press-couple the Chrono-thermostat on the mount (2). To replace the batteries, release the Chrono-thermostat (4) from the wall mount (2) and repeat the above operations. At the end of the installation, remove the protective film from the display of the chrono-thermostat.

Gateway – Chrono-thermostat coupling.
After having powered the generator, the Gateway and the Chrono-thermostat, wait 30 seconds before performing any setting on the system so that communication between the Gateway, generator and Chrono-thermostat is properly established.

• N.B. : all “Smartech Plus” chrono-thermostats are already configured to work correctly with your Gateway, so they do not need any additional configuration to make them work.

In case of a malfunction, the Gateway and Thermostat can be re-coupled by proceeding as follows:

• make sure you have turned on the Gateway for at least 5 minutes;
• keep the “Reset” button on the Gateway pressed until the indication on the “BLE” LED switches from 5 quick blinks a second to one blink a second;
• with Chrono-thermostat set on the main window, press and hold the same key for 3 seconds until the “Mode” or “Program” menu appears, then rotate the Chronothermostat to display the “Settings” menu. At this point again press and hold the key to select the “Diagnostic” menu and press to confirm and to enter the menu;
• press the Chrono-thermostat again, the message “Pairing” will appear on the display. When “Disconnect” appears, the Chrono-thermostat is paired to the Gateway;
• press and hold the Chrono-thermostat to go back to the main menu;
• switch off (removing power) and switch the Gateway back o

Application download and installation on mobile devices (smartphone)
Using the mobile device on which to install the application, connect to the App store of reference: App Store (Apple) or Play Store (Android) and type in “Immergas Smartech” in the search field. The app works with IOS 12 operating system or higher (Apple) and Android 10 or higher. Select the free “Smartech” application and wait for its download and installation on the mobile device used.
Open the “Smartech” app and download the instruction manual by pressing the “Instructions and warnings”button. Follow its instructions to register and pair it with the installed Smartech Plus system.
The manual can be downloaded from the website www. immergas.com.

N.B: the name of the Wi-Fi network and password to which Smartech Plus will be connected must not contain the “&” symbol and the encryption methodology must be WPA2 PSK; otherwise, malfunctions could occur.
Type of system configuration without Wi-Fi connection.

The Smartech Plus system is paired to the type of generator connected by completing the user registration procedure on the “Smartech” app (paragraph 1.8). If there is no WiFi connection available when first starting the system (and therefore the above-mentioned procedure cannot be performed), the type of generator connected can be selected temporarily as follows:

• make the electrical connections on the Gateway as described in paragraph 1.5, then power the device;
• insert the batteries in the Chrono-thermostat;
• once the Immergas logo is displayed, keep the Chrono-thermostat pressed until the list of the type of generators appears;
• rotate the Chrono-thermostat to the desired type of generator;
• press the Chrono-thermostat to confirm.

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.

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 generator 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).
