Vent cycle
b
Each time that the boiler is powered, an automatic vent cycle is carried out lasting
6 min. When the vent cycle is in progress, all heat requests are inhibited except for
domestic hot water ones when the boiler is not set to OFF, and a scrolling message
at the foot of the page appears on the main page of the REC10CH.

4.4 Adjusting the heating water temperature without an outdoor
temperature sensor connected

4.5 Adjusting the heating water temperature with an outdoor
temperature sensor connected
The outlet temperature value is automatically chosen by the system, which rapidly adjusts
the room temperature according to the variations in the external temperature.To modify the
temperature value, increasing or decreasing it with respect to that automatically calculated
by the electronic board, it is possible to act on the HEATING setpoint by selecting SET in
the REC10CH main screen and choosing the desired comfort level within the range (-5 ÷
+5) (see “4.2.5 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.
4.6 Adjusting the domestic hot water temperature
CASE A: only heating with no external water tank connected - adjustment not applicable.
CASE B: only heating with an external water tank managed by a thermostat - adjustment
not applicable.
CASE C: only heating with an external water tank managed by a probe.
To set the domestic hot water temperature (bath, shower, kitchen, etc.): SET DHW to
choose the desired value between the range [37,5°C ÷ 60°C].

After adding the water tank, DHW is displayed on the “Programme” page. This
function allows the domestic hot water programming timing to be carried out
.
4.8 Boiler start-up
If there is a room thermostat or a programming timer, or the REC10CH 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.

The boiler will be in function until the selected temperature is reached, afterwards it will
be in “standby” again keeping the outlet temperature displayed. If faults arise in ignition or
operations, the boiler performs a “SAFETY STOP”: the triangle signalling faults will flash on
the REC10CH. To identify the fault codes and to reset the appliance, see the section “4.14
Lights and faults”.

If the release attempts do not restart the boiler, contact your local Technical
Assistance Centre.
4.10 Screed heater function
For a low temperature system the boiler has a “screed heater” function that can be activated
in the following way:
