II.3.8.5 FAN
FAN is the "ventilation" function. In this operating mode, the fan s peed
can be s et as desired ( min-med-max- AUTOFAN).
The FAN func tion is onl y acti ve within the room temperature operating
limits from 15°C to 35°C. If the FAN mode is s elected i n models without
the hot (or cold) water circulati ng val ve, the unit can heat (or cool).
II.3.8.6 AUTOFAN
The AUTOFAN function requires the fan speed to be established unless
this is done manuall y. In the c ooling and heating modes, the greater the
difference i n the room temperature from the set-point, the higher the
speed is. T he s peed remai ns fi xed at the mini mum val ue i n the DRY
mode.

II.3.8.7 HEAT
HEAT is the "heati ng" functi on. Even in this oper ating mode, the
adjustment c an be set as desired for maxi mum c omfort, by:
selecting the desired temperature val ue;
setting the fan operating s peed manually (*) or automaticall y
(AUTOFAN);
Activation of the hot water val ve is determined accordi ng to the set-
point configured by the user (see the c hart below), whereas the fan is
activated via the HOT ST ART function (at the selec ted speed or
determined by the AUTOFAN function). When the room temperature
(i.e. the adjustment probe val ue) reaches the set-point, the hot water
val ve is clos ed and the fan is deacti vated.

(*) in case of a fan with an EC-Brushl ess motor, the s peeds are defined
by the followi ng parameters:
P129 = Minimum fan speed is set manuall y (20%).
P130 = Medi um fan speed is set manuall y (60%)
P131 = Maximum fan speed is s et manuall y (100%).
Refer to paragraph II.3.12.1 "Setti ng the three s peeds".
II.3.8.8 HEAT + RESISTANCE
The HEAT + ELECTRICAL RESISTANCE func tion consists of the
HEAT mode with the electrical resistanc e being ac tivated automaticall y
(if declared to be pres ent), acc ording to the detec ted hot water
temperature; it can therefore c omplement or replac e the hot water c oil.
A resistance c an be used (with DIP 5 = ON) for enhanced heating and
establish various hysteresis regardless whether the HOT START
functi on is acti ve or not. Possibl e overheating is prevented by acti vati ng
the fan simultaneousl y with the resistance and remains acti ve for a ti me
equal to P48 (20 s) after it being s witched off. The resistance is
deac tivated as an additi onal precaution if the temperature of the c oil
exc eeds the temperature in parameter P47 (50°C).
