4.13 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 one or all the following functions,
for more information about setting the parameter see the relative paragraph "4.3 Boiler configu-
ration" .
- Domestic domestic hot water delay function: this function introduces a programmed de-
lay in the starting of the boiler in domestic hot water mode. The delay time is given by the
parameter P5.10.
- 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 setpoint + 5°C and switching back on at setpoint + 4°C). Activating this
function the boiler will switch on ad off based on thermostats independent of the domestic hot
water setpoint (off at setpoint + 65°C and switching back on at 63°C).
4.14 Screed heating function
For a low temperature system the boiler has a "screed heating" function that can be activated
in the following way:
ƒ set the boiler to OFF by pressing button 1
ƒ access the technical parameters menu, as indicated in the paragraph "3.23 Access to the
parameters" .
ƒ select the P4 menu and then P4.09 with the keys
(Note: SCREED HEATING is not available if the boiler is a status other than OFF).
ƒ 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 per-
sonnel, only if strictly necessary. The manufacturer declines all responsibility if the parameters
are incorrectly set.

ƒ Check the full stop of the boiler by turning off the system's main switch.
ƒ After a couple of minutes of continuous operation, which can 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 residues evaporate and
it will be possible to carry out the check of the combustion.
