ANTI-CYCLE FUNCTION (TIMER OFF CH):
once the
setpoint has been reached the burner will cycle on and off
until an external control, e.g. time clock cancels the heating
request. This function imposes a set time between the
burner OFF/ON cycles in order to optimise efficiency. The
factory setting is 3 minutes and can be set and confirmed
to a value between 0 min and 20 min.

RESET CH TIMER:
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 AIR
PURGING CYCLE. The factory setting for this parameter
is FUNCTION NOT ACTIVE, select FUNCTION ACTIVE,
confirming the selection for resetting the timings.

DOMESTIC HOT WATER THERMOSTAT:
this parameter
allows you to set the type of DOMESTIC HOT WATER
THERMOSTAT. The factory setting is RELATED, i.e. for
domestic hot water the boiler switches off at se5°C
and restarts at se4°C. Select the ABSOLUTE
values, where 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.

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 preheating 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 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:

CONFIG 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.
6.2.2 CONFIGURATION OF THE ZONE
It is possible to customise the management of the heating
zone by accessing the ZONES MANAGER menu.

-
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 is generated by the
REC10CH MASTER; in this case the REC10CH assumes
the function of an HIU (Human 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 (embedded clock function):
this parameter
enables or disables the embedded clock.
Embedded clock disabled (default) = 0
Central heating is controlled (ON & OFF) by the room
thermostat connection (TA).
Embedded clock enabled = 1
Central heating ON/OFF times are controlled according to
the (default) heating programme, whilst room temperature
is controlled via the room thermostat (TA). Ensure that the
operating mode (‘STATE’ menu) is set to AUTO.
