USER MENU
User Menu configuration parameters
the unit of measure depends from the parameters /5P, /b6
and /b7 (the parameters /5P, /b6 and /b7 belong to the User
Menu; see the chapter User Menu on the page 32), if the
condensing probe is a PTC probe the unit of measure depends
from the parameter / t (the parameter / t belongs to the User
Menu; see the chapter User Menu on the page 32).
F 0
proportional band
It is significant exclusively if the parameter /bE has value 1 or 2 and if
the parameter F A has value 0, it establishes the proportional band
width.
For further informations about the parameter F 0 meaning see the
paragraph Condensing quantity regulation on the page 12.
F 1
condenser fans activation setpoint
It has the same significance of the parameter F 1 of the Operator
Menu; see the chapter Operator Menu on the page 29.
F 6
minimum condenser fans activation setpoint pro-
grammable
It is significant exclusively if the parameter /bE has value 1 or 2 and if
the parameter F A has value 0, it establishes the minimum condenser
fans activation setpoint programmable; the instrument automatically
verifies if the value established with the parameter F 6 is below the
maximum condenser fans activation setpoint programmable estab-
lished with the parameter F 7.
F 7
maximum condenser fans activation setpoint pro-
grammable
It is significant exclusively if the parameter /bE has value 1 or 2 and if
the parameter F A has value 0, it establishes the maximum condenser
fans activation setpoint programmable; the instrument automatically
verifies if the value established with the parameter F 7 is above the
minimum condenser fans activation setpoint programmable established
with the parameter F 6.
F A
condenser fans functioning
It establishes the condenser fans functioning that the instrument must
manage, as indicated:
0
=
the condenser fans functioning is function of the quan-
tity read by the condensing probe (the instrument
automatically divides the proportional band established
with the parameter F 0 in equal fractions according
with the number of relay outputs associated to the
condenser fans, it activates the condenser fans with
sequence every time the quantity read by the con-
densing probe rises above the setpoint established
with the parameter F 1 of a fraction of proportional
band and it deactivates them with sequence when
the quantity read by the condensing probe falls below
the value to which the activation happened of a frac-
tion of proportional band)
1
=
the condenser fans functioning is function of the power
steps loading/unloading (a power step loading/un-
loading gives the automatic activation/deactivation of
a condenser fans).
For further informations about the parameter F A meaning see the
paragraph Condensing quantity regulation on the page 12.
F d
method used to compute which condenser fans
activate/deactivate
It establishes the method used by the instrument to compute which
condenser fans activate/deactivate, as indicated:
0
=
the instrument activates the condenser fans with fixed
sequence and it deactivates them with the reversal
method (for instance if the users associated to the
outputs K5, K6, K7 and K8 are condenser fans, the
instrument activates them beginning from that associ-
ated to the output K5 and it deactivates them with the
reversal method)
1
=
the instrument activates the condenser fans balancing
the total working hours and it deactivates them with
the reversal method (for instance the instrument acti-
vates the condenser fans with sequence beginning
from that with the lower number of total working
hours and it deactivates them with the reversal
method).
F H
number of total working hours of the condenser
fans enough to signal the request of service
It establishes the number of total working hours of a condenser fans
enough to signal the request of service (see the paragraph Alarms on
the page 46).
