• "K reG" Central Heating setting constant (0,5...9,0 - factory setting 3 - Refer to section 25 - Graph 3).
Press +/- buttons to set the value. An high value setting involves a high flow temperature. To set a correct value
of the Central Heating constant K REG, involves the room temperature to match the CH setpoint with ex­ternal tem-
perature changes over.
• "BuilD" A parameter that takes into account the degree of building insulation (1..10 - factory setting 5). When the
outside temperature varies, the room temperature changes at different rates, depending on the building thermal sto-
rage capacity. An high value setting involves a heavy building structures (the room temperature will respond slower
to outside temperature variations; buildings with thick walls or with ex­ternal insulation). A low value setting involves
a light building structures (the room temperature will respond quicker to outside temperature variations; buildings
with a light envelope).
Press +/-
buttons to set the value.
"yselF" CH flow temperature auto setting function Enabled/Disabled (1/0). Factory setting 1. With function enable,

the constant "K reG" is modified to match the room temperature comfort. This function operates with the ex­ternal
sensor connected.
Press +/-
buttons to set the value.
• "aMBon" Room temperature influence Enabled/Disabled (1/0). Factory setting 1. In this case, the rooms tempera-
ture regulation it depends on the flow temperature set ("CH SL").
Press +/- buttons to set the value.
note: refer to the summary table of possible aMBon and MoDul combinations.
• "MoDul" Enable/disable Modulation of flow temperature depending on the room temperature and ex­ternal tempe-
rature value (with ex­ternal sensor connected). (with Room Sensor enabled). A value equal to 1 indicates enabling of
delivery setpoint modulation; a value equal to 0 indicates disabling.
The above value can be modified with the buttons +/-

• "hW pr" Enabling the DHW programmer (only for boilers connected to an ex­ternal hot water tank). Factory setting 1.
• 0: Disabled
• 1: Always enabled
• 2: Enabled with DHW weekly program ("HW PR" refer to section 3.7)
"noFr*" Frost protection Enabled/Disabled (1/0). Factory setting 1.

WarninG: this value must be always enable (1).
• "cool" Summer temperature control Enable/Disable (factory set = 0). By setting this parameter = 1 the function is
enabled and a new boiler operation mode "SUMMER+COOL" is available. This function is added to the ones descri-
bed on section 3.2 of the "instructions for the user" manual: suMMer - Winter - suMMer+cool - heatinG
only - oFF.
To enable the function, presss the
aim of this function is to enable the remote control to adjust the room temperature in summertime by controlling one
or more ex­ternal cooling devices such as a condition machine. In this way, the boiler relay card enables the ex­ternal
condition system when the room temperature is higher than the remote control temperature set value.
When the function operates, the display shows the
