PARAMETER P23 – MODULATING PUMP MINIMUM SPEED
(w/modulating pump and return temperature sensor connected only
)
This parameter is used to set the minimum modulating pump speed during a
heating mode request.
To enter the parameters menu, follow the previously described procedure
(see paragraph 5.2 ‘Accessing the parameters menu’ -steps 1-4).
5. Use
and buttons (D.H.W temperature setting) to modify
the value of the parameter within the prescribed limits (displayed in
percentage):
min = 50 %
max = 70 %
6. Press mode selection button
to confirm and to render the new
parameter operative.
7. To exit from the parameters menu, press simultaneously
and
buttons.
PARAMETER P24 – MODULATING PUMP MAXIMUM SPEED
(w/modulating pump and return temperature sensor connected only)
This parameter is used to set the maximum modulating pump speed during a
heating mode request.
To enter the parameters menu, follow the previously described procedure
(see paragraph 5.2 ‘Accessing the parameters menu’ -steps 1-4).
5. Use
and buttons (D.H.W temperature setting) to modify the
value of the parameter within the prescribed limits (displayed in percentage):
min = 70 %
max = 100 %
6. Press mode selection button
to confirm and to render the new
parameter operative.
7. To exit from the parameters menu, press simultaneously
and
buttons.
PARAMETER P25 – ΔT TIMING T° FLOW/ T° RETURN (w/modulating
pump and return temperature sensor connected only)
This parameter is used to set the timing response of the modulating pump.
To enter the parameters menu, follow the previously described procedure
(see paragraph 5.2 ‘Accessing the parameters menu’ - steps 1-4).
5. Use
and buttons (D.H.W temperature setting) to modify the
value of the parameter within the prescribed limits (displayed in seconds):
min = 20
max = 100
6. Press mode selection button
to confirm and to render the new
parameter operative.
7. To exit from the parameters menu, press simultaneously
and
buttons.
