HEATING AND HOT WATER
5.4 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 rather than
[20°C - 45 °C] for low temperature systems.

5.5 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 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 setpoint.
5.6 Adjustment of the domestic hot water
temperature
To adjust the domestic hot water temperature (bath, shower, kitchen, etc.),
set the DOMESTIC HOT WATER setpoint selecting SET on the main
screen of the REC10 and selecting the desired value within the range
[37.5°C - 60°C].
PREHEATING
5.7 "Preheating" function
It is possible to access the PREHEATING function selecting SET on the
main screen of the REC10.
Setting PREHEATING = 1 the boiler's domestic hot water function
activates. This function keeps the water in the domestic hot water
exchanger hot, to reduce standby times when a request is made. When the
preheating function is enabled, the symbol P comes on with a steady light
at the top with respect to the hot water icon. During burner ignition following
a preheating request, the symbol P starts flashing.

5.8 Boiler start-up
If there is a room thermostat or a programming timer, or the REC10
MASTER is set as an ambient regulator, it is necessary that these are on
and that they have been adjusted to a temperature higher than the ambient
temperature so that the boiler switches on.
The boiler will be in standby until the burner switches on following a heat
request.
The display shows " " to indicate the presence of a flame.
