Table summarising the combination of the AMBON and MODUL functions
AMBON MODUL
FUNCTION OF THE B/-
1 1 Regulation of ambient temperature (modulating delivery temperature)
0 1
With external probe : KREG curves regulation
Without external probe : Regulation of calculated delivery temperature.
(it is advisable to set MODUL = 0)
0 0 Regulation of delivery temperature setpoint.
1 0 Regulation of ambient temperature (fixed delivery temperature)
• “HW PR” Enabling the DHW programmer (0-1-2). Factory setting 1.
• 0: 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 - COOL - HEATING ONLY -
OFF.
To activate the function press the button repeatedly until the display shows the symbol to the right of the hour. The purpose
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 blinks on the display during the
request for operation in this mode. To connect the relay board, see the SERVICE instructions.
20.2 ADDITIONAL INFORMATION
For more detailed technical information, please consult the “SERVICE INSTRUCTIONS”.
• “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 b/- per modificare tale valore.
N.B.
: See the table summarising the possible combinations of AMBON and MODUL.
• “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.
Press the b/- to modify this value.
N.B.
: See the table summarising the possible combinations of AMBON and MODUL.
