6.4 ADJUSTING THE HEATING WATER
TEMPERATURE WITHOUT AN
OUTDOOR TEMPERATURE SENSOR
CONNECTED
When there is no outdoor temperature sensor, the boiler
operates at a fixed-point, the HEATING setpoint in this case
can be set selecting SET on the main screen of the REC10
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 (default is high temperature).

6.5 ADJUSTING THE HEATING WATER
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 the
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 setpoint by selecting SET on the
main screen of the REC10 and selecting within the range
(-5 - +5) the desired comfort level (see “6.2.5 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 setpoint.
6.6 ADJUSTING THE DOMESTIC HOT
WATER TEMPERATURE
CASE A:
only heating with no external water tank connected
- adjustment not applicable.
CASE B:

6.8 BOILER START-UP
In order to initiate a heating request, it is essential that any time
or temperature control is set to an ON period and at a higher
than current ambient temperature respectively. The boiler will
be in standby until the burner switches on following a heat
request. The display shows “ ” to indicate the presence of
