7.2 Functioning with an external sensor (Optional)
If the LAGO FB OT+ remote control is fitted with an outdoor temperature sensor, it can calculate the
heating temperature of heating installation Nº 1 according with the outside weather conditions at
each particular time, with optimum adjustment of the heating installation conditions for improved
heating comfort in the home and energy savings.
The maximum temperature and an operating curve for heating circuit Nº 1, the heating times and
the room temperatures desired can all be selected on the remote control (see instructions enclosed
with the LAGO FB OT+ remote control). The LAGO FB OT+ remote control calculates the required
boiler temperature at each particular time, depending on the temperature inside the home and the
outside weather conditions, in accordance with the operating curve selected (parameter 01 on the
“User Menu"
of the LAGO FB OT+), switching the heating on and off in accordance with the heating
times and the room temperatures programmed.
Depending on the type of heating circuit, the following adjustments should be made:
Conventional heating installation (direct circuit)
In setting 01 of the LAGO FB OT+
“User Menu"
, select a curve of at least 1. The maximum boiler
temperature can also be selected on the LAGO FB OT+ remote control.
Installing low temperature heating (mixed circuit)
In setting 01 of the LAGO FB OT+
“User Menu”
, select a curve of less than 0.8. We also
recommend selecting a maximum flow temperature NO HIGHER THAN 85ºC, to protect the
underfloor heating installation from overheating. To do this, select the maximum flow
temperature of heating circuit 1 in setting 07 of the LAGO FB OT+
“Service Menu”
.

NOTE: The "AF outdoor temperature sensor" indicated in the instructions manual of remote
controller is not compatible with the boiler, so it is compulsory the use of "EVT outdoor
sensor" (provided within the boiler) to measure the outdoor temperature.
7.3 DHW function
When the remote control is connected to an Avanttia boiler, the desired DHW temperature and the
desired hours for DHW use can be selected on the LAGO FB OT+ remote control. The LAGO FB OT+
remote control regulates the DHW tank temperature at each particular time, and enables or
disables the DHW function according to the times scheduled.
