- ANTI-CYCLE FUNCTION: this parameter allows you to change the ANTI-CYCLE
FUNCTION, regarding the delay time introduced for re-igniting the burner in the face of
an off due to the heating temperature being reached. The factory setting is 3 minutes and
can be set and confirmed to a value between 0 min and 20 min.

ANTI-CYCLE FUNCTION
- RESET CH TIMERS: this parameter allows you to reset the REDUCED HEATING
MAXIMUM OUTPUT TIMING, during which the speed of the fan is limited to 75% of the
maximum heating output that has been set, and the FORCED HEATING TIMING OFF.
The factory setting is FUNCTION NOT ACTIVE, select FUNCTION ACTIVE and confirm the
choice for resetting the timings.

DOMESTIC HOT WATER THERMOSTATS: this parameter allows you to set the type
of DOMESTIC HOT WATER THERMOSTATS. The factory setting is RELATED, i.e. for
domestic hot water the boiler switches off at se5°C and restarts at se4°C.
Selecting ABSOLUTE value, the boiler for domestic hot water will still switch off at 65°C
and restart at 63°C.

PREHEATING: parameter PREHEATING = 1 (function active, P symbol on steady).
This function keeps the water in the domestic hot water exchanger hot, to reduce
standby times when a request is made. During a pre-heating request, the P symbol
starts flashing. With PREHEATING = 0, the symbol P switches off aand the function is
deactivate. The function is not active when the boiler is OFF.

PREHEATING
- TOUCH & GO: if you do not want PREHEATING to be always active and you want
hot water immediately ready, it is possible to preheat the domestic hot water just a
few moments before taking it. Set the parameter to PREHEATING = 2, to activate the
TOUCH&GO function. This function allows you, by opening and closing the tap, to start
the instantaneous pre-heating that prepare the hot water only for that water take.
- DHW DELAY: this parameter allows you to set the delayed starting of the boiler
in domestic hot water mode. The factory setting of this parameter is 0 and can be
programmed within the range 0 - 60 sec.
- DO_AUX1: through this value it is possible to configure the functions associated with the
digital output used to manage the additional pump and the zone valve. The factory setting
for this parameter is 0 and can be set within the 0 - 2 range with the following meaning:
Pin 1 and 2 of X21 Jumper not present Jumpered
DO_AUX1 = 0 additional pump management zone valve management
DO_AUX1 = 1 zone valve management zone valve management
DO_AUX1 = 2 additional pump management additional pump management
- CONGIF OTBUS : this parameter is used to enable the remote control of the boiler via
an OpenTherm device:
1 = FACTORY VALUE. OTBus function enabled. The message “OPEN THERM
CONNECTED” will appear on the display, when an OTBus device connected.
b
The OpenTherm connection is not enabled in the presence of a heat pump.
0 = OTBus function disabled. If this parameter is set at 0, any possible OTBus
connection is instantaneously interrupted.
4.2.2 Configuration of the zone
It is possible to customise the management of the heating zone by accessing the ZONES

- TYPE OF ACTUATION: set the parameter in question to ITRF05/AKM (default value)
- TYPE OF HEAT REQUEST: this parameter allows you to specify the type of heat
request, it is possible to choose from among the following options:
THERMOSTAT (factory setting): the heat request is generated with an ON/OFF
thermostat
REC10CH MASTER : the heat request to the boiler is generated by the REC10CH
MASTER that assumes the function of MACHINE INTERFACE
- TYPE OF ZONE: this parameter allows you to specify the type of zone to be heated, it
is possible to choose from among the following options:
HIGH TEMPERATURE (factory setting)
LOW TEMPERATURE
- MIN SET HEAT; this parameter allows you to specify the minimum heating setpoint that
is possible (range 20°C - 80.5°C, default 20°C for high temperature systems - range
20°C - 45°C, default 20°C for low temperature systems)
- MAX SET HEAT: this parameter allows you to specify the maximum heating setpoint that
is possible (range 20°C - 80.5°C, default 80.5°C for high temperature systems - range
20°C - 45°C, default 45°C for low temperature systems)
- CHANGING NAME: this parameter allows you to attribute a specific name to the heating zone
- POR: this parameter allows you to enable the central heating programming timing for the
zone concerned if the heat request is carried out using a room thermostat.
Programming timing not enabled = 0
When the room thermostat contact closes the heat request is always met without any
time band limitation.
Programming timing enabled = 1
When the room thermostat contact closes the heat request is enabled according to the
programming timing.
Note : In this case make sure that the operating mode of the zone is set to AUTO in the
STATE menu.
4.2.3 Time band scheduling function
Set up the REC10CH for the time schedule, setting the parameter POR = 1 (see “4.2.2
Configuration of the zone”). Set the time slots by selecting from the main screen MENU

4.2.4 Setting the thermoregulation
Thermoregulation only works with the outdoor temperature sensor installed/connected and
active only for the HEATING function. The temperature measured by the outdoor temperature
sensor is displayed on the initial page in the top right, alternating with the display of the time.
When thermoregulation is enabled (outdoor temperature sensor present), the algorithm for
automatically calculating the outlet setpoint depends on the type of heat request . In any case, the
thermoregulation algorithm will not directly use the outdoor temperature, but rather a calculated
outdoor temperature that takes into account the building’s insulation: in buildings that are well
insulated, the outdoor temperature variations will have less impact than those that are poorly
insulated by comparison.
Enabling THERMOREGULATION occurs in the following way:
