Make sure that your Smartphone is connected to this network.
• power the Gateway and check that the batteries have been inserted in
the chrono-thermostat, wait a couple of minutes;
• quickly press the “Reset” button 5 times. e "Cloud" and "Ble" LEDs
will light up together;
• the Gateway turns o and on again;
• when the two LEDs "Cloud" and "Ble" ash together once per second,
the Gateway is in Smartech_cong_AP mode.
N.B.: if you have already connected the Gateway to your account, but want
to change the Wi-Fi connection to which you are connected, simply repeat
the 4 points above. en select one of the Chrono-thermostats associated
to the Gateway you want to recongure by changing the password through

2 DEVICE CONNECTED TO A GENERATOR.
Operation of a generator connected to Smartech Plus can be modulated
or On/O type depending on the paired generator model and the type of
electrical connection made (see installation instruction leaet).
If the connection between the Smartech Plus Gateway and the generator
is made via IMG Bus (only enabled models), it will be in modulated oper-
ation and the generator display will show the remote control symbol (see
installation instruction leaet).
Otherwise if the connection is made via the room thermostat (TA) contact,
operation will be the ON/OFF type.
• On/Off operation: Smartech Plus allows you to set, using the
Chrono-thermostat or the App, the desired room temperature and the
operating mode: manual or automatic, according to the set weekly pro-
gramming. e ow temperature will be kept constant until the desired
room temperature is reached.
• Modulated operation: the ow temperature will be changed by adjusting
it to the actual needs of the room being heated, in order to obtain the
desired room temperature with extreme precision and therefore with
evident saving in costs. In this mode, in addition to the settings available
in On/O mode, Smartech Plus acts a remote control and, by means
of the Chrono-thermostat or the App, you may intervene on the main
parameters, such as ow and domestic hot water temperature and view
any error codes. e control panel of the generator is disabled; however
the reset button, the shutdown button (O only) and the display showing
the operating status remain active. Furthermore operation with external
probe (see paragraph 3.5) and, when paired with boilers with storage tank
unit, the domestic hot water programming (see paragraphs 3.14 to 3.18)
are enabled.
N.B.: a few seconds can pass from when any parameter is set from the mobile
device before seeing it on the chrono-thermostat and/or on the generator.

2.2 SELECTION OF OPERATING MODE.
e buttons (Ref. 1, Fig. 13) allow you to select the following operating
modes: OFF, Summer, Winter, Cooling.
N.B.: the room antifreeze function is active in the modes: OFF, winter.
• O mode ( ). is mode guarantees the room antifreeze function.
• Summer mode ( ). In this mode the system is enabled for producing
domestic hot water excluding space central heating.
• Winter mode ( ). In winter mode the system is enabled for producing
domestic hot water and for space central heating.
e room temperature is maintained constant at the set value.
• Cooling mode ( ). In cooling mode the system is enabled for the
DHW production and to control an outdoor condensing unit (only for
models set-up) for space cooling.
N.B.: Aer selecting the operating mode, wait for the symbol to turn red
conrming that the generator has made the change.
2.3 ROOM TEMPERATURE SETTING.
To set the desired room temperature, simply rotate the knob (Ref. 9, Fig.
13) on the main screen. e screen will show, in real time, the room tem-
perature set (Ref. 7, Fig. 13).
Any room temperature from +4,5°C to +30°C can be selected, which will be
kept constant until new adjustments are made or a dierent mode is selected.
