1.3.2
DHW 3-star function
This function is included on boiler models with instantaneous hot
water function, with PAR 47 = 1 the function activates when MAN
or AUTO mode is set in the ON bands.
Moreover, this function:
– is activated if, during a domestic hot water (DHW) request, the
burner turns on for more than 5 seconds
– the function keeps the burner active (at minimum power) at the
end of the DHW request, depending on the temperature of the
primary heat exchanger
– the function has a maximum duration of 1 hour
– the total execution time is reloaded only if the 3-star function is
interrupted by a DHW request
– if the 3-star function is interrupted by a heat request from the
heating circuit, or by a request with higher priority, the function
will be deactivated.
m
CAUTION
When the "DHW 3-star" function is activated, it is rec-
ommended to set the "Hot water set" to a value below
45°C to prevent excessive temperatures when water
starts being drawn.
m
CAUTION
Setting of the remote control SIME HOME PLUS: to dis-
able the DHW 3-star function (enabling in ECO mode),
set the domestic hot water (DHW) function to AUTO
mode and disable the MON-SUN period for all time
bands.
