"AMBON" Enable/disable the Ambient Probe of the climate controller (factory setting 1). The value 1 indicates that the
•
ambient probe is enabled while 0 indicates that it is disabled (factory setting 1). In these conditions the temperature
control in the rooms is a function of the chosen boiler delivery temperature ("CH SL"). If the climate controller is installed
in the boiler, the function must be excluded.
Press the buttons +/-
N.B.
: See the table summarising the possible combinations of AMBON and MODUL.
"T ADJ " Reading correction of the remote control Room Sensor (factory setting 0.0°C). It allows correction of the Room
•
Sensor reading by a value ranging from -3.0°C to 3.0°C, with a resolution of 0.1°C. The value may be set using the but-
tons +/-
. The function is enabled only if the unit of measurement is °C
"MODUL" Enable/disable modulation of the delivery temperature as a function of the ambient temperature (with
•
Ambient Probe enabled) and of the outside temperature (if external probe is present). Factory setting 1. The value 1
indicates that modulation of the delivery temperature is enabled while 0 indicates that it is disabled.

• 1: Always enabled
• 2: Enabled with weekly DHW programme ("HW PR" see section 3.7)
"NOFR" Enable/disable boiler frost protection function (factory setting 1). The value 1 indicates that the ambient
•
frost protection function is enabled while 0 indicates that it is disabled.
ATTENZIONE: always leave this function enabled (1).
•
"COOL" Enable/disable ambient temperature control in summer (factory setting = 0). Setting this parameter at 1 enables the
function and adds a new boiler operating status as in section 3.2: SUMMER - WINTER - SUMMER+COOL - HEATING ONLY -
OFF.
To activate the function press the button
of this function is to enable the use of the climate controller to control, in summer, the ignition of one of more external conditio-
ning devices (for example air conditioners). In this way the boiler relay board activates the external conditioning system when the
ambient temperature exceeds the temperature value set on the climate controller. The symbol
request for operation in this mode. To connect the relay board, see the SERVICE instructions.
For more detailed technical information, please consult the "SERVICE INSTRUCTIONS".
