13.2 PROCEDURE FOR SETTING THE PARAMETERS OF
OPERATION
To modify the parameters that determine the mode of hybrid
operation on call of the external probe Pb2 follow the
instructions below:
- Set the outside temperature above which one is wishes to use
only the Booster's renewable energy external to heat pump both
for the production of DHW and for the heating production,
acting on the parameter AR21. However, above this
temperature it will remain activates the "integration boiler" mode
on call of the technical water probe Pb1 to guarantee a
temperature lower limit of the technical water below which one
does not can go down. For example, if parameter AR21 is set to
3 ° C, parameter AR09 at 48 ° C and parameter AR12 at 2 ° C
if we were in a favorable climate with 15 ° C outside
temperature but in the face of a huge DHW withdrawal the
storage temperature decreased below 48 ° C (AR09) then the
boiler will be activated automatically then switch off at a
temperature of 50 ° C (AR09 + AR12).
- Set the outside temperature below which yes wishes to
completely disable the Booster external to heat pump
and use only the boiler for the production of DHW than for
heating production going to act on parameter AR25 (outside air
temperature below of which the Booster is deactivated) and on
parameter AR21 (outdoor air temperature below which it is
activated the boiler). In the outside temperature range that goes
from the value of parameter AR21 to AR25 we will have a
combined hybrid operation with the 2 generators with
simultaneous operation.
- Simultaneously with the activation of the operation “only
boiler "it is possible to set a sliding temperature
of the
technical water set-point so as to obtain a temperature
of
system delivery that increases in a way
proportional to
decreasing air temperature
external. To proceed with this
function set
the value of the parameter ST08 and ST03 at
the temperature of
fine climatic curve (ex 65 ° C as shown in
the graph above)
reported), further set the SD03 parameters
(negative differential that determines the initial value of the
climatic curve with respect to the final value, ex 10 ° C as
from
graph above), SD07 (temperature differential
external
dynamic set-point, ex 5 ° C as graph
above) and SD05
(outdoor air temperature set for
the determination of the end
of the temperature increase
of technical water storage (ex -
5 ° C as shown in the diagram above
reported.
To make the above settings determine the
correct
functioning of the hybrid system make sure that
the boiler
switch "IC" is in the ON position and the diverter
boiler is in
the "INTEGRATION" position as indicated in
paragraph 8.2.
Also check that the digital control unit e
External booster
control is active in heating mode
and that the external Pb2
probe has been connected correctly
as indicated in chapter
12. Last check to make is on the boiler control unit
physically positioned above the pump control unit
of heat, it too must be in HEATING mode
with a set-point
temperature greater than or equal to the parameter
13.
