DEVICE CONNECTED TO A GENERATOR.

Operation of a generator connected to Smartech Plus can be modulated
or On/Off type depending on the paired generator model and the type of
electrical connection made (see installation instruction leaflet).
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 leaflet).
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. The flow temperature will be kept constant until the desired
room temperature is reached.
• Modulated operation: the flow 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/Off 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 flow and domestic hot water temperature and view
any error codes. The control panel of the generator is disabled; however
the reset button, the shutdown button (Off 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.
