Adjusting the heating output temperature
without an outdoor temperature sensor
When there is no outdoor temperature sensor, the boiler operates at
a fixed-point, the HEATING set point in this case can be set selecting
SET on the main screen and selecting the desired value within the range
[40°C - 80.5°C] for high temperature systems or [20°C - 45 °C] for low
temperature systems.
5.5
Adjusting heating output temperature with an
outdoor temperature sensor connected
When an outdoor temperature sensor is installed, the outlet temperature
is automatically selected by the system, which quickly adjusts the ambient
temperature according to variations in the outdoor temperature. If you
want to change the temperature, raising it or lowering it with respect to that
automatically calculated by the electronic board, it is possible to change the
HEATING set point by selecting SET on the main screen and selecting
within the range (-5 - +5) the desired comfort level (see section "5.2.4
Setting the thermoregulation").
Note: when there is an outdoor temperature sensor connected it is still
possible to have the boiler operate at a fixed point setting the values of MIN
SP HEAT and MAX SP HEAT at the desired HEATING set point.
