GENERAL REMARKS
Parameter for confi guring solar collector pump operation; you can choose between the following three options:
0 = OFF (factory setting) ==> the solar collector pump is always off
P6.13
1 = ON ==> the solar collector pump is always on
2 = AUTO ==> the solar collector pump switches on and off according to the rules of solar management
Used to activate the storage of an alarm history. Default 0; the value automatically changes to 1 after 2 hours of operation
P7.01
This parameter allows periodic control of the boiler according to an operating period set in parameter P7.07.
There are three setting values:
0 = function disabled
1 = function enabled according to the following rule:
if P7.07 < 4 the display shows the CFS signal
if P7.07 = 0 the display shows the SFS (STOP FOR SERVICE) signal which indicates the permanent inhibition of all requests for heating and domestic hot water.
P7.06
Not resettable
2 = function enabled:
when P7.07 = 0 the display shows the CFS signal without any stop of operation
In this condition, the INFO menu (line I044), displays the number of days that have passed since the CFS signal appeared (P7.07 = 0)
b
The CFS signal occurs at 10 min intervals for the duration of 1 min, 1 month before the end of the period set in parameter P7.07.
Fixed operating period for the service call (parameter P7.06)
P7.07
Automatic function that is activated at the fi rst power supply or after 60 days of non-use (electrically powered boiler). In this mode the boiler, for 60 minu-tes, limits
the heating power to a minimum and the maximum DHW temperature to 55°C. Activating the chimney sweep temporarily disables this function. During execution, the
water pressure icon flashes (0,5sec on – 0.5sec off).
P7.08
0 = FACTORY VALUE, high efficiency mode disabled
1 = high efficiency mode enabled
This parameter is used to enable remote management of the boiler (in case of REC10H). There are three setting values:
0 = FACTORY VALUE. The interface on the machine is operational, remote control via ModBus is enabled
P8.01
1 = the interface on the machine is operational, remote control via ModBus is disabled
2 = the interface on the machine is not operational, the remote control is enabled via REC10H. Only the MENU key remains active to modify parameter P8.01.
This parameter is used to enable the remote control of the boiler via an OpenTherm device:
0 = OT+ function disabled (remote boiler control via an OT+ device is not possible). If this parameter is set at 0, the OT+ connection (if present) will be immediately
P8.03
interrupted
1 = FACTORY VALUE. OT+ function enabled (an OT+ device can be connected for remote boiler control). When an OT+ device is connected to the boiler, the message
"Ot" appears on the display.
Cascade confi guration - When the parameter is programmed at 0 the boiler operates in a single boiler confi guration, it is not provided in a cascade system. Setting the
parameter to 1,2,3,4 for each module defi nes the unique address to identify the boiler in the cascade system. By programming parameter P9.01=1 and using a single
P9.01
boiler, the boiler can be used individually by exploiting the cascade architecture devices (REC12 + MSC), in this case, however, the boiler will have the limitations
indicated for cascade confi gurations (P9.01 = 1 or 2 or 3 or 4).
Additional boiler fl ow range - Used only when the boiler is in a cascade system to limit the calculation of the temperature control of each individual boiler. Default
P9.02
value 80 - Modify only in special applications where it is necessary to have the fl ow temperature up to 90°C, in these cases set to 90°C
1.15 Configuring a system with REC10
The Condexa HPR boiler, in single application, can be in-
serted in a system where a REC10 or REC10H and BE mana-
gement boards are present (BE15 for solar thermal manage-
ment, BE16 for management of direct or mixed zones, BE17
for of the DHW/system diverter relative to the heat pump
and/or photovoltaic. Use the CE4 connector located under
the boiler shelf to connect the remote control.
Set the parameter P8.01 (BUS 485 CONFIG. ) = 2.

If a REC10 or REC10H is present, for system parameterisation,
refer to the programming manual of the REC itself.

1.15.1 Particular programming of parameter P9.01
The boiler provides for the possibility of special technical
programming.
By programming parameter P9.01=1 and using a single boi-
ler, the boiler can be used individually by exploiting the de-
vices of the cascade architecture (REC12 + MSC), in this case,
however, the boiler will have the limitations indicated for
the cascade configurations (P9 .01 = 1 or 2 or 3 or 4).
