displays the domestic hot water temperature unless there is a heating request in progress,
in which case the boiler’s outlet temperature is displayed.

4.4 Adjusting the heating water temperature without an outdoor
temperature sensor connected
The HEATING setpoint can be set by selecting SET in the REC10CH main screen and choosing
[40°C ÷ 80.5°C] for high temperature systems and [20°C ÷ 45°C] for low temperature systems.

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 section “4.2.4 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.
4.6 Adjusting the domestic hot water temperature
To set the domestic hot water temperature (bath, shower, kitchen, etc.): SET HOT
WATER to choose the desired value between the range [37,5°C ÷ 60°C].

4.7 “Preheating” function
Access to SET PREHEATING menu to activate this function.
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 pre-heating 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 pre-heating request, the symbol P starts flashing. However, setting the parameter
PREHEATING = 2 activates the Touch&Go function, the boiler carries out, only if necessary,
just one pre-heating cycle after each take of domestic hot water. To deactivate the pre-
heating function, set the parameter to PREHEATING = 0, the symbol “P” switches off. The
function is not active when the boiler is OFF.

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”.

In the event of a lockout, it is possible to try and reset normal operations by pressing “ENTER”
on the REC10CH when the fault message is displayed to reset the alarm in progress.

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:
- set the boiler to OFF
- select SCREED HEATING (Note: SCREED HEATING is not available if the boiler is not OFF)
FUNCTION ACTIVE or FUNCTION NOT ACTIVE and confirm to enable /disable
the function.

SCREED HEATING
The screed heater function, when active, is signalled on the main screen by the scrolling
message at the bottom of the SCREED HEATING FUNCTION IN PROGRESS - OUTLET
TEMPERATURE page. The “screed heater” function lasts 168 hours (7 days) during
which, in the zones configured as low temperature, a heating request is simulated with an
initial zone outlet of 20°C, then increased in line with the table on the side. Accessing the
INFO menu from the main page of the REC10CH it is possible to display the TIME FUNC
SCREED HEATING value regarding the number of hours since the start of the function.
Once activated, the function takes priority, if the machine is shut down by disconnecting
the power supply, when it is restarted the function picks up from where it was interrupted.
The function can be interrupted before its end by putting the machine in a condition other
than OFF or else by selecting DEACTIVATE FUNCTION from the relative menu. Note : The
temperature and increase values can be set to different values only by qualified personnel,
only if strictly necessary. The manufacturer declines all responsibility if the parameters are
incorrectly set.

4.11 Checks during and after the first commissioning
After starting up, check that the boiler carries out the start-up procedures and subsequent
shut-down properly. Check the domestic hot water operation by opening a hot water tap
in SUMMER mode or WINTER mode. Check the full stop of the boiler by turning off the
system’s main switch. After a couple of minutes of continuous operation to be obtained
by turning the system’s main switch to “on”, setting the boiler mode selector to Summer
and by keeping open the domestic hot water device, the binders and manufacturing waste
evaporate and it will be possible to carry out:
- checking the combustion.
