5.8.10 SPECIAL DOMESTIC HOT WATER FUNCTIONS
The boiler has special functions more a more efficient
management of the domestic hot water when there a high
domestic hot water temperature input. By programming
the P5.11 parameter it is possible to activate the following
function, for more information about setting the parameter see
the relative paragraph “5.5 Boiler configuration”.
- Absolute thermostats domestic hot water function: normally
the boiler in domestic hot water mode switches on and off
based on thermostats related to the value of the domestic
hot water setpoint (off at se 5°C and switching back
on at se 4°C). Activating this function the boiler will
switch on ad off based on thermostats independent of the
domestic hot water setpoint (off at se 65°C and
switching back on at 63°C).
5.8.11 SCREED HEATING FUNCTION
For a low temperature system the boiler has a “screed heating”
function that can be activated in the following way:
set the boiler to OFF by pressing button 1
access the technical parameters menu, as indicated in the
paragraph “
5.1 Access to the parameters”
select the P4 menu and then P4.09 with the keys

status other than OFF).
To activate the function set the parameter to 1, to deactivate
it set the parameter to 0.
The “SCREED HEATING” 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 interface
it is possible to display the I0.01 value regarding the number
of hours that have passed since the activation 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 it has finished by
setting the boiler to a status other than OFF or by selecting
P4.09 = 0 from the menu P4.
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.
